  • map_open_recordadded

    Open the complete record behind one map marker, or behind a saved reference. Returns: { record, recordRef, billing: { billed, unit, reason }, notice }. `record` is the same Record object search_offenders returns. `recordRef` ('mr_...') is a lasting reference: keep it to open the same record later, after the marker id has expired. Billing: one record open per person per map response, at the account's record-open rate (published price $0.035 per open; an account's agreed rate may differ) — so open a marker only when the user wants that person's record, not every marker in a view or along a route. - The same marker id again is free (`reason: 'marker_already_opened'`). - A new map_viewport, map_area, map_route or map_group answer carries new ids; opening the same person from it is a new charge. - Opening by `recordRef` is one record open, then free for 24 hours. A record just opened from a marker is also free by its reference for 24 hours. `billing.billed` says whether THIS open was charged. Marker ids work for 24 hours (410 `marker_expired` after that). A 410 `record_no_longer_listed` means the registry no longer lists the person; it is not billed. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).

  • map_groupadded

    List the people behind a many-people pin or an approximate-area pin. Returns: { total, page, perPage, totalPages, kind: 'address' | 'area', named, members: [ { id, addressType, label, housingStatus, hasPhoto } ] }. Members carry `label` only when the group id came from a view at zoom 15 or closer (`named: true`). Each member `id` opens with map_open_record. Billing: one map request per page. A group id works for 24 hours and only for the account it was issued to; after that, call map_viewport again. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).

  • map_routeadded

    Exact counts of registered addresses along one walking or bus route. Counts a corridor either side of the line, a radius around each stop, or both, and returns exact numbers per leg and per stop with nameless pins and their distances. Never an estimate and never partial: the answer is complete or the call fails without a charge. Returns: { shape: 'route', profile, measure, detail, datasetVersion, complete, lengthMiles, corridorMiles, stopRadiusFeet, parcelAllowanceFeet, units, total, corridorTotal, stopsTotal, breakdown {street, housed, homeless, incarcerated}, legs: [ {leg, fromStop, toStop, lengthMiles, count} ], stops: [ {stopId, alongMiles, count, nearestFeet, markerIds} ], markers: [ {id, lat, lng, precision, addressType, distanceMiles, leg, alongMiles, nearestStop, stopDistanceFeet} ], groups[], approximate {count, areas[]}, unplaced {count, states}, externalId, notice, routeNotice }. - `total` = distinct people with a street address in the corridor or a stop's reach; leg counts sum to `corridorTotal`. - Pins carry NO NAMES. A `groups` entry (several people at one address) and an `approximate.areas` entry (people placed only at the middle of a ZIP, city or county; never in `total`) open with map_group. - To see who one marker is, call map_open_record with its `id` — a separate charge at the account's record-open rate (published price $0.035 per open; an account's agreed rate may differ). Open only the records the user asks for, not every marker on the route. - More than 300 pins at detail=full is a 422 `route_too_many_people` that carries the exact counts and is not charged: use detail='count' or split the route. A count shows REGISTERED ADDRESSES, NOT WHERE ANYONE IS, and is not a rating of the route. Never describe a route as safe or unsafe; relay `notice` and `routeNotice`. It supports the user's process; it is not a legal determination. Billing: route units, each one map request ($2 per 1,000): one per started mile of measured corridor plus one per 10 stops when stop radii are measured (minimum 1); `units` in the answer says how many. detail='count' costs the same. E.g. a 17.4-mile bus route with 35 stops = 18 + 4 = 22 units. Test mode is free. The Map API must be turned on for the account. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).

  • map_areaadded

    Get what to draw inside a drawn shape: a polygon, or a line with a buffer. The same answer as map_viewport for the shape's bounding box, limited to what is inside the shape, at the same detail levels (clusters, pins, or named pins at zoom 15+). The response adds `shape: 'polygon' | 'route'`. Returns: { shape, mode, zoom, bbox, datasetVersion, total, breakdown {street, housed, homeless, incarcerated}, clusters[], markers[], areas[], unplaced {count, states}, notice }. - A marker with `id: null` and a `groupId` stands for several people at one address: call map_group with that `groupId`. - `areas` are people placed only at the middle of a ZIP, city or county. Never describe them as being at an exact spot. - To see who one marker is, call map_open_record with its `id`. A pin shows a REGISTERED ADDRESS, not a person's current location — say so when you describe a result (`notice` carries the sentence). Billing: one map request per call ($2 per 1,000), whatever the shape holds. Marker and group ids work for 24 hours. The Map API must be turned on for the account (403 `map_not_enabled` otherwise); `sandbox=true` works without it. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).

  • map_viewportadded

    Get what to draw for one map view: clusters, pins, or named pins. Send the view as `bbox`, or as `lat` + `lng` + `radius_miles`. The detail returned depends on the zoom the view is answered at (the response states it in `zoom`): - zoom 3-12 -> mode 'clusters': a count per grid cell. Each cluster has `count`, `bbox`, `breakdown` and `expansionZoom` (fit the map to `bbox` at that zoom and the cluster comes apart). - zoom 13-14 -> mode 'pins': one pin per address, position only, no name. - zoom 15+ -> mode 'markers': pins with `label` (first initial and last name), `housingStatus`, `hasPhoto`, `registryState`. A close view holding more than 300 pins is answered as clusters instead. Returns: { mode, zoom, bbox, datasetVersion, total, breakdown {street, housed, homeless, incarcerated}, clusters[], markers[], areas[], unplaced {count, states}, notice }. In radius mode also `center`, `radiusMiles` and `withinRadius` (exact), and each marker has `distanceMiles`. - A marker with `id: null` and a `groupId` stands for several people at one address: call map_group with that `groupId`. - `areas` are people placed only at the middle of a ZIP, city or county; each has a `groupId` too. Never describe them as being at an exact spot. - `unplaced` counts people in the states this view touches who have no mappable address. Mention it rather than implying the map shows everyone. - To see who one marker is, call map_open_record with its `id`. A pin shows a REGISTERED ADDRESS, not a person's current location — say so when you describe a result (`notice` carries the sentence). Billing: one map request per call ($2 per 1,000), whatever the view holds. Marker and group ids work for 24 hours. The Map API must be turned on for the account (the API answers 403 `map_not_enabled` otherwise); `sandbox=true` works without it. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).

Tools (10)

batch_searchRun many person/location lookups in one call (row-in / row-out). Each row goes through the SAME engine as search_offenders, so a row's records are identical to what a single search would return. A row that fails is reported with status='error' in place and never aborts the batch. Max 1000 rows. Returns: { count, results: [ { index, status, counts{records,sourcesQueried, sourcesIncomplete}, warnings: [str], records: [Record], error? } ] } in input order. ★ A row with `counts.sourcesIncomplete > 0` could not be searched to the end — its `records` are a LOWER BOUND, not a clean 'no match'. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).
get_criminal_coverageList the criminal-record jurisdictions searched, with kind and status. Use it to discover which states and counties are reachable and which are answering today, before relying on an empty result. Depth is uneven by design: counties publish independently, so a state with many county jurisdictions is not "better covered" than one that publishes a single statewide source — it is differently structured. Returns the jurisdiction roster; each entry carries its code, the state it belongs to, the kind of records it holds (jail / prison / court / warrant / registry) and whether it is currently answering.
get_registry_coverageList every registry we cover plus its scope, legal status, and health. Public coverage catalog (no API key required). Use it to discover the `jurisdictions` codes accepted by search_offenders / batch_search and to check per-registry freshness/health before relying on a result. Returns: { count, registries: [ SourceInfo ] } where each SourceInfo is: - id: registry code (e.g. 'IL', 'TX', 'PR') - name: human-readable registry name - covers: [state codes] a registry covers ('*' = national / all) - scope: 'state' | 'national' - status: 'live' | 'building' - legal: { commercialUse: 'allowed'|'restricted'|'prohibited'|'unknown' } - health: { lastSuccessAt, typicalLatencyMs, ageSeconds, freshFor } `health` is OPERATIONAL COVERAGE METADATA about our ingest schedule, published for transparency. It is NOT a quality warning about a search result: a search serves every registry's best available data regardless of `freshFor`, so a registry listing only 'weekly' still contributes its records to a freshness='daily' search. Do NOT tell a user their search results are stale, unreliable or out of date on the basis of these fields — they are not. The only completeness signal that belongs in an answer is `counts.sourcesIncomplete` / `warnings[]` from the search response itself.
map_areaGet what to draw inside a drawn shape: a polygon, or a line with a buffer. The same answer as map_viewport for the shape's bounding box, limited to what is inside the shape, at the same detail levels (clusters, pins, or named pins at zoom 15+). The response adds `shape: 'polygon' | 'route'`. Returns: { shape, mode, zoom, bbox, datasetVersion, total, breakdown {street, housed, homeless, incarcerated}, clusters[], markers[], areas[], unplaced {count, states}, notice }. - A marker with `id: null` and a `groupId` stands for several people at one address: call map_group with that `groupId`. - `areas` are people placed only at the middle of a ZIP, city or county. Never describe them as being at an exact spot. - To see who one marker is, call map_open_record with its `id`. A pin shows a REGISTERED ADDRESS, not a person's current location — say so when you describe a result (`notice` carries the sentence). Billing: one map request per call ($2 per 1,000), whatever the shape holds. Marker and group ids work for 24 hours. The Map API must be turned on for the account (403 `map_not_enabled` otherwise); `sandbox=true` works without it. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).
map_groupList the people behind a many-people pin or an approximate-area pin. Returns: { total, page, perPage, totalPages, kind: 'address' | 'area', named, members: [ { id, addressType, label, housingStatus, hasPhoto } ] }. Members carry `label` only when the group id came from a view at zoom 15 or closer (`named: true`). Each member `id` opens with map_open_record. Billing: one map request per page. A group id works for 24 hours and only for the account it was issued to; after that, call map_viewport again. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).
map_open_recordOpen the complete record behind one map marker, or behind a saved reference. Returns: { record, recordRef, billing: { billed, unit, reason }, notice }. `record` is the same Record object search_offenders returns. `recordRef` ('mr_...') is a lasting reference: keep it to open the same record later, after the marker id has expired. Billing: one record open per person per map response, at the account's record-open rate (published price $0.035 per open; an account's agreed rate may differ) — so open a marker only when the user wants that person's record, not every marker in a view or along a route. - The same marker id again is free (`reason: 'marker_already_opened'`). - A new map_viewport, map_area, map_route or map_group answer carries new ids; opening the same person from it is a new charge. - Opening by `recordRef` is one record open, then free for 24 hours. A record just opened from a marker is also free by its reference for 24 hours. `billing.billed` says whether THIS open was charged. Marker ids work for 24 hours (410 `marker_expired` after that). A 410 `record_no_longer_listed` means the registry no longer lists the person; it is not billed. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).
map_routeExact counts of registered addresses along one walking or bus route. Counts a corridor either side of the line, a radius around each stop, or both, and returns exact numbers per leg and per stop with nameless pins and their distances. Never an estimate and never partial: the answer is complete or the call fails without a charge. Returns: { shape: 'route', profile, measure, detail, datasetVersion, complete, lengthMiles, corridorMiles, stopRadiusFeet, parcelAllowanceFeet, units, total, corridorTotal, stopsTotal, breakdown {street, housed, homeless, incarcerated}, legs: [ {leg, fromStop, toStop, lengthMiles, count} ], stops: [ {stopId, alongMiles, count, nearestFeet, markerIds} ], markers: [ {id, lat, lng, precision, addressType, distanceMiles, leg, alongMiles, nearestStop, stopDistanceFeet} ], groups[], approximate {count, areas[]}, unplaced {count, states}, externalId, notice, routeNotice }. - `total` = distinct people with a street address in the corridor or a stop's reach; leg counts sum to `corridorTotal`. - Pins carry NO NAMES. A `groups` entry (several people at one address) and an `approximate.areas` entry (people placed only at the middle of a ZIP, city or county; never in `total`) open with map_group. - To see who one marker is, call map_open_record with its `id` — a separate charge at the account's record-open rate (published price $0.035 per open; an account's agreed rate may differ). Open only the records the user asks for, not every marker on the route. - More than 300 pins at detail=full is a 422 `route_too_many_people` that carries the exact counts and is not charged: use detail='count' or split the route. A count shows REGISTERED ADDRESSES, NOT WHERE ANYONE IS, and is not a rating of the route. Never describe a route as safe or unsafe; relay `notice` and `routeNotice`. It supports the user's process; it is not a legal determination. Billing: route units, each one map request ($2 per 1,000): one per started mile of measured corridor plus one per 10 stops when stop radii are measured (minimum 1); `units` in the answer says how many. detail='count' costs the same. E.g. a 17.4-mile bus route with 35 stops = 18 + 4 = 22 units. Test mode is free. The Map API must be turned on for the account. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).
map_viewportGet what to draw for one map view: clusters, pins, or named pins. Send the view as `bbox`, or as `lat` + `lng` + `radius_miles`. The detail returned depends on the zoom the view is answered at (the response states it in `zoom`): - zoom 3-12 -> mode 'clusters': a count per grid cell. Each cluster has `count`, `bbox`, `breakdown` and `expansionZoom` (fit the map to `bbox` at that zoom and the cluster comes apart). - zoom 13-14 -> mode 'pins': one pin per address, position only, no name. - zoom 15+ -> mode 'markers': pins with `label` (first initial and last name), `housingStatus`, `hasPhoto`, `registryState`. A close view holding more than 300 pins is answered as clusters instead. Returns: { mode, zoom, bbox, datasetVersion, total, breakdown {street, housed, homeless, incarcerated}, clusters[], markers[], areas[], unplaced {count, states}, notice }. In radius mode also `center`, `radiusMiles` and `withinRadius` (exact), and each marker has `distanceMiles`. - A marker with `id: null` and a `groupId` stands for several people at one address: call map_group with that `groupId`. - `areas` are people placed only at the middle of a ZIP, city or county; each has a `groupId` too. Never describe them as being at an exact spot. - `unplaced` counts people in the states this view touches who have no mappable address. Mention it rather than implying the map shows everyone. - To see who one marker is, call map_open_record with its `id`. A pin shows a REGISTERED ADDRESS, not a person's current location — say so when you describe a result (`notice` carries the sentence). Billing: one map request per call ($2 per 1,000), whatever the view holds. Marker and group ids work for 24 hours. The Map API must be turned on for the account (the API answers 403 `map_not_enabled` otherwise); `sandbox=true` works without it. Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).
search_criminalSearch US criminal records — county jail bookings, state prison custody, court cases and warrants. Covers county jail rosters, statewide prison systems, court sources, warrant systems and statewide registries across the states, DC and the territories, plus the federal layer — which is a separate system holding offences no state search will surface. A surname is REQUIRED. Supply firstName and a DOB or birth year wherever you have them: a bare common surname returns thousands of people, and the scoring cannot tell you which one is yours. Each record carries `recordType`, and YOU MUST READ IT BEFORE CHARACTERISING ANYONE: - a jail booking is an ARREST-stage record — charges at booking are frequently reduced, dismissed, or never filed. It is NOT a conviction. - prison custody implies a sentence, and therefore a conviction. - a court record carries the DISPOSITION — the authoritative statement of how a case actually ended. - a warrant means the person is SOUGHT. Nothing has been tested. Never describe someone as convicted on the strength of a booking record. Records also carry: name, aliases, dob/birthYear/dobPrecision, sex, race, state, county, custody status and facility, sentence and parole detail, `cases`, `sources` (per-source citation), and `matchConfidence`/`matchBasis` explaining why it matched. `counts.records` is the total found and `counts.recordsReturned` the number in this page. Not a consumer report: results must not be used for FCRA-covered decisions (employment, tenancy, credit) without appropriate process.
search_offendersSearch US sex-offender registries for one person and/or location. Fans out across all 58 registries (or the ones named in `jurisdictions`), de-duplicates people across registries, scores each match, and returns the normalized records. Supply whatever identifiers you have — all args are optional but at least a name, location, or free-text `q` should be given. Returns a SearchResponse object (docs/openapi.yaml / FIELD-DICTIONARY.md): - status: 'complete' | 'partial' (partial = a source errored, or a source could not be searched to completion) - counts: { records, sourcesQueried, sourcesIncomplete } - warnings: [str] — ALWAYS present, `[]` when the search ran clean - sourceStatus: [ { source, status, matched, fromCache, note, incomplete, incompleteReason } ] per-registry outcome ★ READ `counts.sourcesIncomplete` BEFORE REPORTING A RESULT. Above 0, `records` is a LOWER BOUND: those registries could not be searched to the end, and an empty or short result is NOT evidence that a person is unregistered. Say so. `warnings[0]` states it in plain language; relay it rather than summarising it away. - records: [ Record ], each with: recordId, matchConfidence, matchBasis[], name {first, middle, last, suffix, full}, aliases[], nicknames[], dob, dobPrecision, age, sex, race, ethnicity, height, weight, eyeColor, hairColor, marks, addresses[{type,line1,city,county,state,zipcode,lat,lng}], offense {crime,statute,riskLevel,tier,convictionDate,...}, flags{absconder,predator}, source {jurisdiction,registryName,recordUrl,scrapedAt,sourceUpdatedAt}, sources[], dobVerification, unverified (offenses[], stateData, images[] are populated only when extensive=true) Auth: uses the caller's X-API-Key (request header or OFFENDERSEARCH_API_KEY env).
