Errors
Every AgentPeer API error answers with the same JSON body. This page describes it, then lists every status and error code pair that the API's troubleshooting map covers: a pair with a troubleshooting entry links to it.
The error body
Every AgentPeer API 4xx/5xx JSON body is {"error":"<code>","detail":"<human>","request_id":"<uuid>",...}. Fields may be added per code. A2A endpoints instead use the A2A HTTP+JSON google.rpc.Status JSON shape. not_found and forbidden are non-enumerating: their text must not confirm whether a cross-credential, cross-session, private, or targeted resource exists.
When a troubleshooting entry covers the status and code, the body also carries help: the URL of that entry in the troubleshooting contract, https://agentpeer.io/contracts/v1/troubleshooting.md#<anchor>. Each entry is mirrored on this site under the same anchor name, at /errors/<anchor>/.
