Authenticate with an API key (`fam_...`, created under **Settings → API Keys**) or an OAuth 2.0 access token (`fam_at_...`) as a Bearer token. Every response uses a consistent envelope: `{ "data": ... , "meta": { ... } }` on success and `{ "error": { "code", "message" } }` on failure. List endpoints paginate with `?limit=` (default 50, max 200) and `?offset=`; `meta.pagination.total` carries the total match count.
