• 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 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.

  Parameters:

  • from (required) — string — Sender mailbox: base58 Ed25519 public key (must be a declared mailbox and must equal the payer of record).
  • ciphertext (required) — string — Base64 ciphertext, decoded <= 16384 bytes. The relay stores opaque ciphertext only and holds no private keys.
  • idempotency_key (required) — string — 16-128 chars; a duplicate key is answered with the original receipt, free.
  • client_ts (required) — string — ISO 8601 sender-claimed timestamp.
  • signature (required) — string — Base64 Ed25519 signature over the a2a-msg/v1 payload (from, to, ciphertext hash, client_ts, idempotency_key).
  • to — string — Recipient mailbox pubkey (exactly one of to / to_handle).
  • to_handle — string — Recipient handle (exactly one of to / to_handle).

• 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 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.

  Parameters:

  • url — string — Site URL; its /sitemap.xml is used.
  • sitemap_url — string — Explicit sitemap URL (alternative to url).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• 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.

  Parameters:

  • url — string
  • sitemap_url — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• 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 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.

  Parameters:

• 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.

  Parameters:

  • url (required) — string

• fee_oracle_recipe

  Solana landing recipe: one call that fuses the fee oracle's /estimate and /optimize — send an unsigned transaction, get the simulated compute-unit limit, priority-fee tiers (economy=p50, balanced=p75, fast=p95) with the chosen tier marked, the expected total fee, the ready-to-sign rewritten transaction, and a precomputed 3-rung escalation ladder. Optional fee_cap_lamports: if the chosen tier exceeds it, the answer flags cap_exceeded and returns no rewritten transaction. Paid: $0.01 flat per call via x402. Free pre-check at POST /toll/fees/recipe/preflight (same JSON body) validates structurally and states the exact price before payment; our-side failure after settlement queues an automatic refund intent (you only pay for delivered answers).

  • urgency — string — economy=p50, balanced=p75, fast=p95 priority-fee percentile; selects the tier baked into rewritten_tx.

• sec_alerts_poll_alerts

  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.

  Parameters:

  • watch_id (required) — string — The bearer credential issued by sec_alerts_register_watch.
  • cursor — string — Optional opaque cursor from a prior poll's next_cursor (or the registration initial_cursor); omit for the watch's initial cursor. A cursor bound to a different watch is refused free (bad_cursor).

• sec_alerts_register_watch

  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.

  Parameters:

  • ciks — array — CIK strings, 1-10 digits each, at most 25 — provide ciks and/or tickers.
  • forms — array — Optional form strings, at most 20; omit for all forms. A filter matches the exact form or its base form (8-K matches 8-K and 8-K/A).
  • tickers — array — Ticker symbols, at most 25, resolved to CIKs at registration.
  • amendments_only — boolean — Optional, default false; filters filing events only, never deletion flags.
  • include_deletions — boolean — Optional, default false; deletion flags are produced only from records whose provenance marks them weekly-index-reconciliation-sourced.

• arena_quote

  Free quote for one verification run: the fixed 3-call plan for the target plus the constituent test-call cost summed from the target endpoint's own listed prices. An unknown or ineligible target is answered free, before payment. HTTP equivalent: POST /run/quote.

  Parameters:

  • service_id (required) — string — The Layer 0 service id to test (see arena_eligible).
  • endpoint_path — string — Optional: the specific paid endpoint path to test.

• arena_run

  Start one paid-and-judged verification run: the arena funds, executes the fixed 3-call suite itself, judges it, and builds the Layer 0 write-back events. An unknown or ineligible target is answered free, before payment. Paid via x402 on Solana (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]). HTTP equivalents: POST /run (standard), POST /run/full-service, POST /run/retest. Prices (RULED): standard single-endpoint run $25; full-service run $50; re-test run $10. What the standard $25 includes: one arena-executed verification run of a single endpoint — the fixed 3-call suite (1 free pre-check call judged on challenge quality + 2 settled paid calls with per-run varied inputs, executed by the arena, never by the seller), judging on settled / delivered / payload_valid / challenge_ok with latency recorded, one verdict (pass / partial / fail) with per-dimension summaries, Layer 0 write-back events (verification evidence, delivery-proof delta, and a state recommendation on pass only), leaderboard eligibility from the same evidence, and the run record retained as digests + call records (payloads never stored). The run price is the full price of the run — constituent test-call costs are the arena's cost, not an additional charge. The $50 full-service run includes the same suite executed for EVERY paid endpoint of one service, a verdict per endpoint, a service-level dimension summary, and write-back per endpoint. The $10 re-test includes an identical suite, judging and write-back for an endpoint the same seller has already run; a re-test inside the 24h reputation window is delivered in full but flagged reputation_counted: false.

  Parameters:

  • service_id (required) — string — The Layer 0 service id to test (see arena_eligible).
  • tier — string — Optional price tier: standard ($25, default), full_service ($50), retest ($10; same seller must have a prior run of the target).
  • run_id — string — Optional: caller-chosen run id; one is generated when omitted.
  • seller_ref — string — Optional: the seller's reference for this run.
  • endpoint_path — string — Optional: the specific paid endpoint path to test.

• arena_result

  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=.

  Parameters:

  • id (required) — string — The run id returned by arena_run.
