# Verify credential

`GET /v1/auth/verify`

Checks whether the bearer credential on this request is valid, without reading any data. Accepts an API key or an OAuth access token. Intended for clients that must validate a credential before use (for example an MCP server verifying an incoming token) so they do not have to call a data endpoint to do it.

## Response `200`

Credential is valid

- object
  - `valid` boolean
  - `userId` string
  - `name` string, nullable — Display name of the credential's owner.
  - `email` string, nullable — Email of the credential's owner.
  - `authType` 'api_key' | 'oauth' | 'session'
  - `scope` string, nullable — Granted OAuth scopes, space-separated. Null for API keys.

## Other responses
