The Celo x402 marketplace
Pay-per-call tools for AI agents - settled in USDC on Celo in ~1 second, no signup, no API keys. The wallet is the account.
An open index of the whole Celo 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 · 2026-10-09T07:30:26.000Z
A paid canary buys tools over the Celo rail daily (facilitator: x402.celo.org) - 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.
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.
