Health of x402 sellers and facilitators: Factline’s nightly seller probes and hourly facilitator probes, proxied live per request.

Tools

• x402_facilitator_health(facilitator?) — all tracked x402 facilitators with current status (up/down/unknown), 7-day uptime, latency and supported networks, or one by id, name or URL. Refreshes hourly.
• x402_seller_health(query?, tag?, network?, limit?) — x402 sellers ranked by 30-day payers, each with a health reading (healthy/degraded/unhealthy/insufficient_data/unprobed) from nightly probes. At most 100 per call; narrow with query, tag or network to reach the rest.
• x402_seller_lookup(origin) — one seller by origin, host or URL: per-day probe history, uptime, listed payTo wallets, health reading. Use before paying a seller.

Every response carries source, cite_as, cadence, data_as_of and warnings.

Auth

Keyless. Factline offered these feeds free of charge for agent use.

Data sources

• Factline, x402 Seller Health Index — nightly probes of sellers listed in public x402 catalogues.
• Factline, x402 Facilitator Health — hourly probes of x402 facilitators.

Cite as “Source: Factline (factline.dev)”. Cadence: sellers nightly, facilitators hourly; data_as_of is the latest probe, and a warnings entry appears when it is older than the cadence implies.

Reading the results

• Absence is not health. found:false or count:0 means unknown or unmatched, never “fine”. The pack says so in the payload.
• The seller feed lists at most 100 sellers per request with no paging (about 1,000 tracked); coverage_note states the cut.
• health and status_now are this pack’s reading of Factline’s numbers (rules in health_basis / status_basis), not Factline’s own verdict. A facilitator that requires an API key is probed on /supported only (verify_tested: false).
• Seller probes check that a sample endpoint answers a valid payment challenge; no payment is made and nothing is said about the quality of what the seller sells.
