• 2026-10-15check_broker_authorityadded

  Does this broker hold active broker authority, and what does FMCSA's record say around it? Give exactly one of mc_number (the broker's MC docket, written MC123456, MC-123456 or 123456) or usdot_number. Paid, flat price; billed whenever the carrier resolves, including when it holds no broker authority (that is the answer). An unknown docket or USDOT number is a free not_found; giving neither or both, or a docket FMCSA lists under several carriers without naming a holder, is a free error. Returns holds_active_broker_authority and the broker dockets (docket number, status, how current that status is, active types, first grant and last event dates); the bond (BMC-84/85) on-file flag with its continuity (coverage unbroken since, current gap, closed lapses in 24 and 60 months, longest gap, data-through date); the authority event history (grants, reinstatements, revocations, suspensions, in total and over 24 and 60 months); revocation, suspension and reinstatement flags; and the identity linkage screen. A record, not a recommendation or a rating. How far to trust "holds active broker authority": it is as complete as the two FMCSA sources behind it. FMCSA froze its legacy licensing archive on 2026-05-14, so a docket known only from it (status_source legacy_li) describes that date, and a docket whose status changed afterwards and is not yet on FMCSA's live MOTUS roster is not seen. There is no independent count of real brokers to check against. Confirm the broker's current authority and bond with FMCSA before relying on it.

  before

  One dated, hashed record of what public FMCSA data shows about a carrier, built for a broker's carrier-vetting file. Paid, flat price. It gathers, in one response: the carrier's current profile (authority, insurance flags, FMCSA safety rating and its date, out-of-service orders, fleet and classifications, MCS-150 filing date, first authority grant, revocation, suspension and reinstatement history), the SMS inspection and violation summary with out-of-service rates, the trailing-24-month crash summary, the last year's changes, and the identity-linkage triage screen. review_factors lists each factor a documented review commonly considers and whether this record carries it. It is a record, not a score. It never says a carrier is safe or unsafe, "Unrated" is reported as exactly that, and it is not legal advice or a statement that choosing a carrier was reasonable. This project's own safety_tier_derived is deliberately left out. Integrity: record_hash is the SHA-256 of the record's canonical JSON (see hash_method) without record_hash and verify_url. Keep the record; later, GET verify_url (free) confirms that we issued exactly that hash, when, and for which carrier, so an edited copy is detectable. If the hash cannot be registered the call returns registry_unavailable and is not billed. An unknown USDOT number is a free not_found.

  before

  Free. Finds the USDOT number(s) for an operating-authority docket number (MC, MX or FF), so a broker holding the MC number from a rate confirmation can reach the other tools, which take a USDOT number. mc_number may be written "MC123456", "MC-123456", "mc 123456" or just "123456" (a bare number is taken as MC). Almost every docket number belongs to one carrier; a few have been carried by more than one USDOT number, so usdot_numbers is a list (at most 10). Returns only the identifiers, no names or addresses. An unknown docket number is a not_found error; an unreadable one is invalid_arguments. Never billed.

  Free. Finds the USDOT number for an operating-authority docket number (MC, MX or FF), so a broker holding the MC number from a rate confirmation can reach the other tools, which take a USDOT number. mc_number may be written "MC123456", "MC-123456", "mc 123456" or just "123456" (a bare number is taken as MC); zero-padding is ignored, because FMCSA's own files disagree on it. authority_holder_usdot_number is the carrier FMCSA's authority records tie the docket to, and there is never more than one. usdot_numbers lists every carrier that lists the docket (FMCSA's census lists about 26,000 dockets under a second carrier too, so a docket can legitimately appear under two), the holder first. docket_status and status_source say how current that is: "motus" is live, "legacy_li" is FMCSA's archive as of 2026-05-14, "census" is the census file's code. Returns only identifiers and a status, no names or addresses. An unknown docket is a not_found error; an unreadable one is invalid_arguments. Never billed.

• 2026-10-15get_inspection_crash_summaryadded

  A carrier's roadside inspection, violation and crash summary on its own. Paid, flat price; billed whenever the USDOT number resolves, even if the carrier had no inspections (that is the finding). An unknown number is a free not_found. inspections (SMS data, a 24-month window that ends weeks before today: read window_end): inspection counts by driver and vehicle, out-of-service counts and rates (FMCSA's own method; no national average is carried, so cite FMCSA's), violation counts in total and by BASIC, last inspection date. When there were no inspections the measures are null, never zero, and data_quality_flags says why: inspection_summary_no_inspections (in SMS, none in the window) or inspection_summary_unavailable (in neither SMS file, so SMS says nothing either way). A carrier inspected only after window_end reads as having none. crashes (federally recordable crashes, trailing 730 days ending at the build date): counts by fatal, injury, tow-away and hazmat release, plus fatalities and injuries and the last crash date. A floor, not a total: about 19% of crash records carry no USDOT number and cannot be attributed to any carrier. Counts, not a rating: this does not say a carrier is safe or unsafe, and it carries no contact information.

• 2026-10-15check_roster_changesadded

  Which carriers on your roster changed on or after a date, and what changed: authority, insurance, out-of-service and the other tracked fields, each with its old and new value. Paid, metered: a base price plus a per-roster-entry price, both shown in get_catalog. roster_usdot_numbers is your own list of USDOT numbers (non-empty, at most settings.roster_screen_max_size distinct entries, currently 100: over the limit is a free invalid_arguments, never a truncation). since is an ISO date, YYYY-MM-DD. A roster entry that matches no carrier is listed in roster_not_found but still counts toward the price. "Nothing changed" is a complete answer and bills like any other; a roster where no entry resolves is a free not_found. How fresh this is: changes appear only when the underlying data is refreshed (roughly weekly lately, with no committed schedule), so a change made at FMCSA today may not be here yet. provenance.record_as_of says how current the data is. Only real changes are returned (the warehouse's one-time "field started being tracked" rows are not). At most settings.roster_changes_max_rows changes come back, newest first; truncated says whether more existed. Carries no contact information, and no change to legal_name, dba_name, phone or email, same as get_safety_history.

  Historical snapshots and changelog entries for a carrier. Paid — you pay only when a call returns records; an exact-key miss is free. changelog may legitimately be empty for a carrier without two distinct-date snapshots yet — a diff needs both. authority_types, oos_orders_active, insurance_bipd_on_file, insurance_cargo_on_file, insurance_bond_on_file, has_been_revoked, and last_revocation_date are null (not false/empty) on a history row recorded before 2026-09-02 — carrier_history wasn't tracking those fields yet, so null there means "not tracked on this date," not a negative answer. Likewise has_been_suspended/last_suspension_date are null before 2026-09-06, and has_authority_reinstated/last_reinstatement_date/ has_insurance_identity_mismatch are null before 2026-09-12, and insurance_cancel_pending/days_to_cancel_effective/ soonest_cancel_effective_date are null before 2026-10-04. changelog holds real changes only (change_kind "value_changed"): the row the warehouse writes when a field first starts being tracked is never returned. About 97% of authority_status changes are dated 2026-09-02, when FMCSA's licensing data switched systems; treat that date's authority_status changes with some caution. Carries no contact information (legal_name, dba_name, addresses, phone, email — removed 2026-09-19, see schemas.CarrierProfile); changelog excludes field_name in {legal_name, dba_name, phone, email} for the same reason — a changed value is still the value.

  Filtered carrier search. Paid — you pay only when a call returns records; a zero-row result is free, same as an exact-key miss. Defaults to Active carriers only — pass include_inactive=true to also see Inactive/Pending. Capped at 100 rows per response regardless of the requested limit; never a full-table dump. Carries no contact information (legal_name, dba_name, addresses, phone, email — removed 2026-09-19, see schemas.CarrierProfile) — a filterable, multi-result endpoint returning personal contact details for whoever matched a filter was the sharpest version of that risk in this product; use lookup_carrier's claimed_name/claimed_street/etc. if you need to confirm a specific carrier's claimed identity.

  Filtered carrier search. Paid — you pay only when a call returns records; a zero-row result is free, same as an exact-key miss. safety_tier filters on safety_tier_derived: 1 = inspected with zero BASIC alerts, up to 6 = all five BASICs alerted. Carriers with no tier (never inspected, or not in SMS) never match a tier filter. Defaults to Active carriers only — pass include_inactive=true to also see Inactive/Pending. Capped at 100 rows per response regardless of the requested limit; never a full-table dump.
