An open index of the whole Avalanche x402 economy - this host plus every independent seller the crawl finds (CDP Bazaar included), each re-probed every 30 minutes. Not a walled market: other venues' listings appear here too.

Our latest own settlement (canary): $0.001 USDC · on-chain receipt · 2026-10-09T07:30:34.000Z

A paid canary buys tools over the Avalanche rail daily (facilitator: PayAI) - uptime proven with real settlements, not pings.

Agent402 runs this index and sells 500+ tools, metered models and reports on the same rails. Our own canary and volume runs are excluded from these figures; the ranked rows measure other sellers on chain and never include the host. Settlements are counted from the sales ledger, which starts 2026-07-03; earlier calls were served and settled but are not itemised in it, so these are not lifetime totals.

Sort

healthy = the last crawl of the origin succeeded, nothing more. dispatch = this host's router will buy from this seller right now; a seller can be listed, healthy and still not dispatch-eligible (no known payment network, or no settlement history on Base yet). The reason is on each row and on /api/index as routerDispatchReason.
