  • a2a_send

    Send 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 x…

  • access_crawl

    Accessibility 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…

  • access_crawl_preflight

    FREE 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_scan

    Accessibility 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 r…

  • access_scan_preflight

    FREE 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.

  • adc_shortlist

    Ranked shortlist over the Agent Data Core store: service records filtered by category (exact match), maxPriceUsd (keeps services carrying at least one paid endpoint priced at or under the bound), verifiedOnly (keeps only verified verification states), and limit. Returns the matching full service records in deterministic id order. $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/datacore/shortlist.

  • adc_snapshot_descriptor

    FREE snapshot descriptor for the Agent Data Core store: returns only the snapshot descriptor — generated_at, service count, and byte size of the exported snapshot document. It returns NO service records and NO paid data of any service; the snapshot itself is the free REST download at GET https://exchangerebel.com/toll/datacore/snapshot. Free — no payment required, call it directly.

  • adc_verification_report

    Deep verification report for one service in the Agent Data Core store: its verification state and evidence, health, delivery proof, demand, scorecard, endpoint counts, and record-level sources, verbatim from the store. An unknown service id is answered free, before payment. $0.05 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/datacore/report.

  • address_bundle

    Address-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. A 1-leg request refuses free — use the leg tool instead. Canada is available inside this bundle only. Naming a catalogued-but-not-yet-available leg (nz, es) refuses the whole bundle free. 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"]).…

  • address_leg_nl

    Netherlands address-validation leg (BAG via PDOK Locatieserver, CC BY 4.0) at $0.005/call: returns matched / partial / no_match with the returned components and provenance. No confidence field. Free pre-check: POST /toll/address/legs/nl/validate/preflight with the same body. $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/address/legs/nl/validate.

  • address_leg_us

    United 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"]). HTTP equivalent: POST https://exchangerebel.com/toll/address/legs/us/validate.

  • anomaly_batch

    Batch anomaly detection: 1..100 series (each 8..10,000 points, <= 100,000 points total), flat $0.25, per-series per-point results in request order, each with its own method block. Free pre-check at POST /toll/anomaly/batch/preflight. $0.25 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/anomaly/batch.

  • anomaly_detect

    Anomaly detection for one numeric time series (8..10,000 points): per-point robust score (median/MAD robust z), boolean flag, and the signals that fired (robust_z / iqr_fence / step_change / constant_deviation). Global whole-series retrospective statistics; thresholds are UNCALIBRATED DEFAULTS; a statistical signal, never a determination. Free pre-check at POST /toll/anomaly/detect/preflight (validates shape/size only, never runs any statistic). $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["x…

  • arena_eligible

    Free: the arena-eligible targets from the Layer 0 store — services with a paid endpoint that carries a price — as descriptors (service id, name, category, verification state, endpoint method/path/summary). Carries no prices. Free — no payment required. HTTP equivalent: GET /eligible.

Show 169 more tools

    Free: read one run's status and result by run_id — lifecycle state, verdict, per-call records (digests only, never payloads), and the write-back events when built. An unknown run id is answered free. HTTP equivalent: GET /run?id=.
