Get the SDKs’ Composer repository
Composer 2’s repository root, at /api/v1/sdk/composer: lists fetchski/attract-cms-api-client and fetchski/attract-cms-laravel, and where their versions are.
Access: any API key of this site that is switched on and not past its expiry date, whatever its scopes and signing mode (npm and Composer can’t sign), sent as Authorization: Bearer fsk_… (what npm, pnpm, Bun and Composer’s bearer auth send); ApiKey fsk_… works too. The key’s network allowlist still applies (403). Anything else, the management key and a signed-in session included, gets 401.
Rate limit: each request spends one of the key’s own reads-per-minute (default 600); over it, 429 with Retry-After.
