x402_assess_services**Paid** ($0.25 USDC on Base, x402). Fresh on-demand AI comparison of a shortlist of listed services for a stated need. Pass-through: it never holds keys, never signs, and never settles. Call without `payment_signature_b64` to get the x402 challenge verbatim, sign it client-side, then retry with the signature to get the report. Optionally add a `probe` target `{ slug, endpoint_path? }` to also test one listed service live: the price becomes $0.25 plus that endpoint price X (non-refundable), and the report gains a `probe_report` block with a verdict and truncated extracts, never the verbatim third-party body.
Parameters not published.
x402_change_eventsFree, read-only feed of what the monitor observed changing on listed services, most recent first, in exactly three event types (`payto_changed`, `price_changed`, `schema_changed`). Filter by `service` (the listing slug: the parameter is named `service`, not `slug`), by `type`, and by `days` (1 to 365, default 90); page with `page` / `per_page` (up to 100 per page). Each event carries the observation timestamp, a diff summary, and the before/after 402 snapshots. Prices inside an event are atomic token amounts, never dollars, and every payout address is returned masked by the API: the feed reports THAT the payTo changed, never the address.
Parameters not published.
x402_check_healthLive status, directory-wide or per service (uptime snapshots, consecutive failures).
Parameters not published.
x402_facilitator_volumesPer-facilitator on-chain-verified settlement volume (today UTC/7d/30d/all) in USD, tx counts, and an on-chain vs listed flag. The `*_24h` fields cover today (UTC) so far, not a trailing 24-hour window.
Parameters not published.
x402_find_best_serviceRanked recommendation for a need, computed server-side (GET /api/v1/best). Ranks mostly by reliability, x402 compliance and price (status, verified, uptime, response time, USD price), with a small (~10%) weight on per-service on-chain traction that can never dominate those three. The answer carries `ranking_version`, **3** today (see below), and a `units` map holding every scoring caveat in full.
Parameters not published.
x402_get_serviceFull detail for one service by slug: endpoints, per-endpoint USD pricing, uptime windows, networks, settlement asset.
Parameters not published.
x402_search_servicesSearch and filter the directory by query, category, network, status, and `signable` (whether the last observed 402 envelope carries the EIP-712 domain parameters a standard x402 client needs in order to sign); sort by newest/uptime/cheapest/endpoints.
Parameters not published.
