Allows apps to authenticate users and obtain access tokens scoped to read or read+write permissions on behalf of the user. **Scopes:** - `read` — Read-only access to the user''s public and private data. - `write` — Read and write access, allowing mutations on behalf of the user. **PKCE Required:** All authorization code requests must include `code_challenge` and `code_challenge_method=S256` parameters.

The password must be your Ethereum private key in hex format (with or without 0x prefix). Example: ``` Authorization: Basic dXNlcm5hbWU6MHgxMjM0NTY3ODkwYWJjZGVmLi4u ``` **How it works:** 1. The API decodes the Basic Auth credentials 2. Extracts the private key from the password field 3. Derives the Ethereum address from the private key 4. Uses this address for authorization checks **Authorization** The derived wallet address must be either: - The wallet of the user being acted upon (direct ownership) - A wallet with an approved, non-revoked grant for the user (manager mode) ' BearerAuth: type: http scheme: bearer bearerFormat: JWT description: 'The API bearer token or OAuth JWT token for the user.
