  description: '## Overview


    The Audius API provides REST access to the world''s largest open music catalog, built on the [Open Audio Protocol](https://openaudio.org). Use it to query and stream tracks, users, playlists, and more—perfect for building music players, discovery apps, and audio-native products.


    ## Key Capabilities


    - **Users** — Profiles, followers, following, search

    - **Tracks** — Search, trending, stream, favorites, reposts

    - **Playlists** — Create, update, browse, curate

    - **Resolve** — Look up content by Audius canonical URLs (e.g. `audius.co/artist/...`)

    - **Explore** — Trending content, charts, discovery

    - **Comments, Tips, Rewards** — Social features and engagement


    ## Authentication


    - **Read-only** — Most endpoints work without credentials. Use an API key for higher rate limits.

    - **Writes** — Upload, favorite, repost, and other mutations require an API key and secret. Get keys at [api.audius.co/plans](https://api.audius.co/plans) or [audius.co/settings](https://audius.co/settings).

    OAuth2:

      description: 'OAuth 2.0 Authorization Code flow with PKCE for third-party applications.


        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.

        '
      flows:
        authorizationCode:
          authorizationUrl: /v1/oauth/authorize
          tokenUrl: /v1/oauth/token
          scopes:
            read: Read-only access to user data
            write: Read and write access on behalf of the user
    BasicAuth:
      type: http
      scheme: basic
      description: 'HTTP Basic Authentication with Ethereum private key for write operations.


        **Authentication**


        Use HTTP Basic Authentication where the password field contains your Ethereum private key:

        ```

        Authorization: Basic <base64(username:privatekey)>

        ```


        The username can be any value. 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)
