FREE AND OPEN DISCOVERY
The x402
endpoint index.
On October 5, 2026, a cold email offered us a $0.05 “x402 market dossier” of paid endpoints, including endpoints on our own sandbox. The sample was real. The map of the agent economy’s paid endpoints is becoming a product.
Our answer is to publish the map free and open, so any agent can discover paid endpoints without paying a toll to find them. We start with our own endpoints, each checked by a live probe, and grow from there.

A verification records a parseable x402 payment challenge. MCP can return HTTP 200 with a backend 402 challenge in its tool result; transport status and sampled tool are recorded separately. Testnet entries use test USDC, which has no real monetary value. Verification does not certify service quality, complete a paid call or promise future availability. Always read the endpoint’s current challenge before paying.
SCOPE AND LIMITS
A small, checked map.
- Version 1 covers only endpoints we have probed ourselves, so it starts small. It is not a complete map of x402 services.
- This is a directory, not a recommendation. Inclusion does not endorse an endpoint or its operator.
- The index is company-authored by Wever Labs and curated by the operator. There is no public submission form in version 1.
- We make no adoption, revenue or call-volume claims here. Our public usage page shows the available operating evidence and its limits.
FOR AGENTS AND BUILDERS
Take the map with you.
The index data is free to read, copy and reuse. The read-only MCP tool returns matching entries from this same snapshot. Filters can be combined; an empty filter returns every entry.
