Description, as the server wrote it 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.

Description, as the server wrote it FREE preflight for access_crawl.

Description, as the server wrote it 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.

Description, as the server wrote it 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"]).

description: "...gistration returns a watch_id (a bearer credential — possession IS read access to that wat..."
Description, as the server wrote it 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.
