  • fact_bank_tendency_preflightadded

    FREE preflight for fact_bank_tendency. Counts only: eligibility, history depth, distinct-value count, freshness, servable/reason_class, and the $0.02 RULED toll quote. No fact values are returned. — no payment required: call directly without payment (no x402 challenge; this tool is free). HTTP equivalent: POST https://exchangerebel.com/toll/facts/tendency/preflight.

  • fact_bank_tendencyadded

    Fact bank TENDENCY, $0.02 per call (x402), price RULED. Computed direction over one (entity, status_field) history with at least 3 facts; the verbatim steps and any rank map are shipped so the computation is checkable. Nominal, period-parameterised and structured fields are refused as not_computable. Call fact_bank_tendency_preflight first to check eligibility for free. — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalent: POST https://exchangerebel.com/toll/facts/tendency.

  • fact_bank_status_preflightadded

    FREE preflight for fact_bank_status. Counts only: existence, coverage counts, per-field history depth, freshness, servable/reason_class, and the $0.01 RULED toll quote. No fact values are returned. — no payment required: call directly without payment (no x402 challenge; this tool is free). HTTP equivalent: POST https://exchangerebel.com/toll/facts/status/preflight.

  • fact_bank_statusadded

    Fact bank STATUS lookup, $0.01 per call (x402), price RULED. Latest-per-status_field current state for one entity, served verbatim with per-fact provenance. Call fact_bank_status_preflight first to check coverage for free. — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalent: POST https://exchangerebel.com/toll/facts/status.

  • fact_bank_healthadded

    FREE fact bank health. Counts only: snapshot_loaded, fact/entity totals, stream labels, store freshness and store_stale flag. — no payment required: call directly without payment (no x402 challenge; this tool is free). HTTP equivalent: GET https://exchangerebel.com/toll/facts/health.

  • fact_bank_catalogadded

    FREE fact bank catalog. Counts and labels only: stream labels, entity and fact counts, field names, op list and RULED prices, store freshness. No fact values. — no payment required: call directly without payment (no x402 challenge; this tool is free). HTTP equivalent: GET https://exchangerebel.com/toll/facts/catalog.

  • transcribe_audioadded

    Transcribe audio with Groq Whisper (whisper-large-v3). $0.005 per minute of audio, per-second prorated — NOT a flat per-call price: billed seconds = ceil(parsed duration to whole seconds); charge = ceil(seconds x 5000 / 60) USDC units (SOL rail: ceil(seconds x 34000 / 60) lamports), quoted exactly by the free preflight (POST /toll/transcribe/preflight) before payment. Accepts WAV/PCM, MP3, Ogg Opus/Vorbis, FLAC, MP4/M4A audio-only (max 25 MB, max 600 s); WebM refused at v1. The MCP adapter converts the tool arguments into the multipart HTTP shape (file part + optional language/model fields). You only pay for delivered answers — any failure after settlement queues an automatic refund. — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalent: POST https://exchangerebel.com/toll/transcribe.

  • sec_alerts_register_watchadded

    Register a watch for SEC EDGAR filing alerts: a set of CIKs and/or tickers plus an optional form-type set. Paid via x402: $0.005 — RULED (5000 USDC units / 33500 SOL lamports). The $0.005 registration price is RULED (Mauricio, 2026-10-20) — the evaluation ladder figure, ruled as proposed. Always call the free preflight first (same body): POST /toll/secalerts/watch/preflight performs all validation, resolves tickers to CIKs, and returns the exact price ($0.005 — RULED) before any payment; an unresolvable ticker is a free unknown_ticker refusal, never a guess. Registration returns a watch_id (a bearer credential — possession IS read access to that watch's alerts view; there is no separate secret, no rotation, and no recovery for a lost watch_id) and its initial cursor: the watch reports only filings first seen after it was created. first_seen_at is ExchangeRebel's own detection timestamp — the moment this service first recorded the filing in its append-only store. The SEC publishes no availability timestamp, so no seller's first-seen time can be anything other than their own observation. For a filer's first-ever touch, the store is seeded from the filer's returned history and first_seen_at is the seed time (records carry seeded:true). You only pay for delivered answers — a registration that fails after settlement writes exactly one refund intent and creates no watch. Price: $0.005 per call (per watch registration). — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalent: POST https://exchangerebel.com/toll/secalerts/watch.

  • sec_alerts_poll_alertsadded

    Poll the alerts view of a registered watch: the filings matching the watch's own rules that this service first saw since the cursor — new filings, /A amendments grouped to their base form, and deletion flags from weekly index reconciliation only. Paid via x402: $0.01 — RULED (10000 USDC units / 68000 SOL lamports) per delivered view — one poll delivers ALL matching events since the cursor, up to 200 per poll; it is NOT charged per event. Always call the free preflight first (same watch_id + cursor): GET /toll/secalerts/alerts/preflight returns the pending-event count only (no event content) — pending_count 0 is the complete free answer, so you never pay for an empty view. A settled poll that still delivers zero writes exactly one refund intent (net charge zero, cursor unmoved). If you lose a response, re-poll the same cursor within 7 days: the delivery record is re-served verbatim and free (redelivered: true). first_seen_at is ExchangeRebel's own detection timestamp — the moment this service first recorded the filing in its append-only store. The SEC publishes no availability timestamp, so no seller's first-seen time can be anything other than their own observation. For a filer's first-ever touch, the store is seeded from the filer's returned history and first_seen_at is the seed time (records carry seeded:true). Deletion flags are issued only for removals confirmed by the weekly full-index reconciliation: a deletion_flag event is produced only from a record whose provenance marks it weekly-index-reconciliation-sourced. Removals noticed when a single filer's submissions record is re-read are never issued as deletion alerts by this service. Until the weekly reconciliation is wired to the live store, deletion flags do not fire in production. Honest crossover: polls cost $0.01 (ruled price) per delivered alerts view. A caller whose watches deliver about 500 events a month is spending about $5.00 a month here — the price of Datamule's $5/month subscription — and continuous, high-volume watchers are better served by that subscription. This service is built for episodic, task-driven agent queries: register a watch, poll it when the task needs the answer, and pay only for delivered views. Price: $0.01 per call (per delivered alerts view). — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalent: GET https://exchangerebel.com/toll/secalerts/alerts.

  • screenshot_renderadded

    Screenshot of one public web page, self-rendered by our own headless Chromium: body {url, tier?: viewport|full-page, width?, height?} -> PNG inline (base64 in JSON) + render metadata. Viewport tier $0.03, full-page tier $0.02 (tier selected in the body; the 402 challenge carries the selected tier's price). Full SSRF fence, refusals free before payment. Free pre-check at POST /toll/screenshot/preflight (shape + full fence incl. resolve-then-pin, no render). $0.03 per call — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalent: POST https://exchangerebel.com/toll/screenshot.

a2a_sendSend one 1:1 direct message through the A2A ciphertext relay: {from, to|to_handle, ciphertext (base64, <= 16384 bytes decoded), idempotency_key, client_ts, signature (Ed25519 over the a2a-msg/v1 payload)} -> delivered receipt. Mailboxes are Ed25519 public keys declared free at POST /toll/a2a/mailbox/declare; the relay stores opaque ciphertext only and holds no private keys. The payer of record must equal the sender mailbox. Undeliverable sends are refused FREE before payment. Free pre-check at POST /toll/a2a/send/preflight. Retention 30 days. 1:1 DM only. $0.005 per call — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalent: POST https://exchangerebel.com/toll/a2a/send.
access_crawlAccessibility findings for every same-origin page in a site's sitemap (max 50 pages) in one combined stored report, priced from the sitemap before payment (x402): $0.05 per page for the first 25 pages, $0.02 per page beyond (price RULED). Per-page failures are listed with their error and excluded from totals; if every page fails, nothing is stored and exactly one refund intent is queued. Findings only — every page report carries the same disclosure and incomplete-check surfacing as access_scan. Call access_crawl_preflight first for the exact price preview for free. Price per call is the tiered sitemap total (RULED). — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalent: POST https://exchangerebel.com/toll/access/crawl.
access_crawl_preflightFREE preflight for access_crawl. Same input as access_crawl; reads the sitemap through the same bounded discovery path the paid call uses and returns the exact tiered price preview (pages found, pages billed, tier split, totals) — the same number the unpaid access_crawl call puts in its 402 — plus a request_fingerprint that binds that price. No page is rendered and nothing is charged. — no payment required: call directly without payment (no x402 challenge; this tool is free). HTTP equivalent: POST https://exchangerebel.com/toll/access/crawl/preflight.
access_scanAccessibility findings for one page from automated checks in a real headless browser, $0.05 per call (x402; price RULED). Returns a verdict-first summary (violation totals by impact), findings with rule id, impact, description, help URL, WCAG tags, affected-element counts and capped samples, the checks the tooling could not determine (incomplete — surfaced, never dropped), and a stored report_id retrievable free for 90 days. Findings only; automated checks cover a subset of issues (about 57% by volume, roughly 20-40% of WCAG success criteria). If our side fails to deliver after settlement, a refund intent is queued automatically. Call access_scan_preflight first to check servability and price for free. — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalent: POST https://exchangerebel.com/toll/access/scan.
access_scan_preflightFREE preflight for access_scan. Same URL input; returns servability, the fence verdict, and the $0.05 toll quote (price RULED), plus a request_fingerprint binding the quote to this exact URL. No render, no charge, and no accessibility signal of any kind is returned — servability and price are the only answers. — no payment required: call directly without payment (no x402 challenge; this tool is free). HTTP equivalent: POST https://exchangerebel.com/toll/access/scan/preflight.
address_bundleAddress-validation bundle at $0.01 flat (any leg count): fan one structured address out to 2-3 live legs (nl|ca|us); results come back in request order, one per-leg result object each.

Free pre-check: POST /toll/address/bundle/validate/preflight. $0.01 per call — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]).

HTTP equivalent: POST https://exchangerebel.com/toll/address/legs/nl/validate.
address_leg_usUnited States address-validation leg (U.S. Census Bureau Census Geocoder) at $0.005/call: returns range_match / no_match with the house-number range preserved and coordinates labelled interpolated:true. A range match is not an existence verdict. address.state is required. Free pre-check: POST /toll/address/legs/us/validate/preflight. $0.005 per call — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]).

ema_changesField-level change events computed between held EMA snapshot generations: per medicine when an identity is given ({ema_product_number}, or a resolved {name} / {inn}), feed-wide (all held product numbers, capped at 100 events per call, truncation flagged) when only {since} is given.

HTTP equivalent: POST https://exchangerebel.com/toll/rpc/. Generic Solana JSON-RPC passthrough (cached, failover proxy): pass the RPC method and its params array.

Viewport tier $0.03, full-page tier $0.02 (tier selected in the body; the 402 challenge carries the selected tier's price). Full SSRF fence, refusals free before payment.

HTTP equivalent: POST https://exchangerebel.com/toll/screenshot.
sec_alerts_poll_alertsPoll the alerts view of a registered watch: the filings matching the watch's own rules that this service first saw since the cursor — new filings, /A amendments grouped to their base form, and deletion flags from weekly index reconciliation only. Paid via x402: $0.01 — RULED (10000 USDC units / 68000 SOL lamports) per delivered view — one poll delivers ALL matching events since the cursor, up to 200 per poll; it is NOT charged per event. Always call the free preflight first (same watch_id + cursor): GET /toll/secalerts/alerts/preflight returns the pending-event count only (no event content) — pending_count 0 is the complete free answer, so you never pay for an empty view. A settled poll that still delivers zero writes exactly one refund intent (net charge zero, cursor unmoved). If you lose a response, re-poll the same cursor within 7 days: the delivery record is re-served verbatim and free (redelivered: true). first_seen_at is ExchangeRebel's own detection timestamp — the moment this service first recorded the filing in its append-only store. The SEC publishes no availability timestamp, so no seller's first-seen time can be anything other than their own observation. For a filer's first-ever touch, the store is seeded from the filer's returned history and first_seen_at is the seed time (records carry seeded:true). Deletion flags are issued only for removals confirmed by the weekly full-index reconciliation: a deletion_flag event is produced only from a record whose provenance marks it weekly-index-reconciliation-sourced. Removals noticed when a single filer's submissions record is re-read are never issued as deletion alerts by this service. Until the weekly reconciliation is wired to the live store, deletion flags do not fire in production. Honest crossover: polls cost $0.01 (ruled price) per delivered alerts view. A caller whose watches deliver about 500 events a month is spending about $5.00 a month here — the price of Datamule's $5/month subscription — and continuous, high-volume watchers are better served by that subscription. This service is built for episodic, task-driven agent queries: register a watch, poll it when the task needs the answer, and pay only for delivered views. Price: $0.01 per call (per delivered alerts view). — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalent: GET https://exchangerebel.com/toll/secalerts/alerts.
sec_alerts_register_watchRegister a watch for SEC EDGAR filing alerts: a set of CIKs and/or tickers plus an optional form-type set. Paid via x402: $0.005 — RULED (5000 USDC units / 33500 SOL lamports). The $0.005 registration price is RULED (Mauricio, 2026-10-20) — the evaluation ladder figure, ruled as proposed. Always call the free preflight first (same body): POST /toll/secalerts/watch/preflight performs all validation, resolves tickers to CIKs, and returns the exact price ($0.005 — RULED) before any payment; an unresolvable ticker is a free unknown_ticker refusal, never a guess. Registration returns a watch_id (a bearer credential — possession IS read access to that watch's alerts view; there is no separate secret, no rotation, and no recovery for a lost watch_id) and its initial cursor: the watch reports only filings first seen after it was created. first_seen_at is ExchangeRebel's own detection timestamp — the moment this service first recorded the filing in its append-only store. The SEC publishes no availability timestamp, so no seller's first-seen time can be anything other than their own observation. For a filer's first-ever touch, the store is seeded from the filer's returned history and first_seen_at is the seed time (records carry seeded:true). You only pay for delivered answers — a registration that fails after settlement writes exactly one refund intent and creates no watch. Price: $0.005 per call (per watch registration). — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]).
