API Overview

The club API implements the Dart Pub Repository Specification v2 and extends it with endpoints for authentication, administration, publishing management, scoring, and discovery. This page covers the conventions shared across all endpoints.

Base URL

All endpoints are relative to your club server URL (configured via SERVER_URL):

https://club.example.com

Authentication

club supports two authentication mechanisms:

Mechanism	Used by	How it’s sent
Session cookies	Web UI	HttpOnly cookies set by POST /api/auth/login
Personal Access Tokens (PATs)	CLI, CI, scripts	Authorization: Bearer club_pat_<...>

PATs are created via POST /api/auth/keys or through the OAuth flow used by the club CLI. Tokens carry scopes (read, write, admin) that are clamped to the user’s role at creation time.

Authorization: Bearer club_pat_a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4

Some endpoints are public and require no auth. These include health, the setup flow, public package metadata, archive downloads, search, user avatars, documentation, login/signup, invite acceptance, and the OAuth flow.

Token Scopes

Scope	Allows
read	Download packages, search, list versions
write	Publish packages, manage package options
admin	User management, package/version deletion, server administration

User Roles

owner (one per server) > admin > member > viewer. A token’s scopes cannot exceed the user’s role. (Legacy: the role previously named editor is now member; old clients sending editor are normalised on parse.)

Content Types

Most endpoints accept and return application/json. Pub Spec v2 endpoints respond with application/vnd.pub.v2+json and the dart pub client sends matching Accept headers.

Archive downloads return application/gzip. The publish upload endpoint accepts either multipart/form-data or a raw application/octet-stream tarball body.

Error Format

All errors use a consistent envelope:

{
  "error": {
    "code": "NotFound",
    "message": "Package 'nonexistent' was not found."
  }
}

See Error Codes for the full list.

Rate Limits

Certain sensitive endpoints are rate-limited per client IP:

Endpoint	Limit
POST /api/auth/login	10 / 15 min
POST /api/auth/signup	10 / 15 min
POST /api/setup/verify, POST /api/setup/complete	5 / 15 min
GET /api/invites/<token>, POST /api/invites/<token>/accept	10 / 15 min

Rate-limited responses return 429 RateLimited.

Security Headers

A security headers middleware is applied globally (including X-Content-Type-Options, X-Frame-Options, Referrer-Policy, and a content security policy).

401 Response Headers

Per the Pub Repository Specification, all 401 Unauthorized responses include a WWW-Authenticate header so the dart pub client can trigger its authentication flow:

WWW-Authenticate: Bearer realm="pub", message="Authentication required."
