## Before you call it

1. Send the key in the `x-api-key` header to `https://api.bundle.social/api/v1`. A missing key returns 401 and a bad key 403
2. Pass `teamId` on most calls. Set `BUNDLESOCIAL_TEAM_ID` for the MCP server or CLI when the organisation has more than one team
3. Set a `referenceKey` on each post and look it up with the reference-key endpoint before retrying a create, because there is no idempotency key
4. Check `GET /api/v1/organization/usage/daily-limits` before bulk scheduling. Failed and deleted posts still count against the monthly quota
5. A person must complete each network's OAuth consent in a browser. Keep prepaid credit for X, where a post costs $0.015 or $0.20 with a link
