  • x402_search_services Your first call when you do not know which x402 service exists for a job: it narrows the directory of listed services to candidates. Filter by free-text query, category, network, live status, and whether the last observed 402 envelope is signable by a standard x402 client; sort by newest, uptime, ch
  • x402_get_service Call this once you hold a slug and are deciding whether to commit to that service: the full record behind a directory row. Live status, uptime over 24h/7d/30d/90d, average response time, networks and settlement asset, every priced endpoint, and the assessment block. include_series=true adds 90 daily
  • x402_find_best_service Call this when you have a need in words and want one service to call rather than a list to read: it is the free ranking step between searching and paying. Pass the need as q, plus any category, network, price cap or verification requirement, and get up to 20 ranked recommendations with the basis eac
  • x402_check_health Call this before you send a payment, or right after a call unexpectedly failed: is this service up right now.

Returns on-chain-verified settlement volume and transaction counts per facilitator for today (UTC), 7d, 30d and all-time, plus a verification flag ('on-chain' once volu
  • x402_assess_services Call this when the free signals have run out: you hold 2 to 8 finalists from x402_search_services or x402_find_best_service, their stored fields do not separate them for YOUR stated need, and choosing wrong costs more than a quarter. It buys one fresh AI assessment reasoned against your question, no
  • x402_change_events Call this before you trust anything you cached about a service, and right after a payment failed for no obvious reason: the monitor's log of what moved under you. Returns payTo, price and 402-schema changes observed on listed services, most recent first, in exactly three event types (payto_changed,
