The machine-payable web

Published x402 endpoints mirrored from the Bazaar: 25,702 of them across 2,508 hosts, with declared prices and failed observations from rotating health samples.

Mirrored from Coinbase CDP x402 Bazaar on 2026-10-19, liveness probed 2026-10-19. Raw: stats.json · catalog.json · health.json.

What a call costs

25,644 endpoints publish a price in an asset whose decimals are known. The other 58 are listed without one — guessing six decimals would print a number wrong by orders of magnitude, so they are excluded from price filters rather than sorted as free.

Find an endpoint

Filter by the requirements of your client. Catalog details are publisher declarations, not a compatibility guarantee.

Price filters exclude unknown prices. A catalog quote is not a live payment offer; confirm the asset, chain and amount before paying.

Before you connect

Health checks cover a rotating sample. Failed observations carry their own date; no recorded failure does not mean a successful check. Even an HTTP response does not prove that authentication, payment or a tool operation will succeed.

1. Check the result’s HTTP method and chain against your x402 client.
2. Obtain the provider’s request schema and current payment terms. The endpoint URL alone is not a complete request example.
3. Review the asset, recipient and amount before authorizing payment. This directory has not verified the paid result.

The 25 largest operators

Concentration is the thing the headline count hides: 25,702 endpoints across 2,508 hosts means the typical operator publishes a handful, and a few publish thousands.

Provenance and removal

This is a mirror of a public registry, republished so it can be queried and so its liveness is knowable. It states no facts of its own about these endpoints beyond whether they answered a request. If you operate one of them and want it gone, open an issue on the repo — no justification needed, and it is removed on the next build.
