Verdicts

bundle.social

The REST API has a public OpenAPI 3.0 description of 194 operations, Markdown docs and published rate limits, and the free plan needs no card. Organisation API keys carry no scopes, there is no idempotency key, and the status page shows one API outage of 4 hours 3 minutes on 31 August 2026.

Upload-Post API + MCP

Free plan with 2 profiles and 10 uploads a month, no card. One account key with no scopes, and the MCP's OAuth grants a single mcp.full scope.

Before you call either

bundle.social

  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

Upload-Post API + MCP

  1. Send Authorization: Apikey <key> on REST. The MCP also takes Bearer
  2. Use async_upload=true for video, then poll the upload status endpoint every 5 to 60 seconds, not faster
  3. Send an Idempotency-Key on every upload so a timed-out retry doesn't post twice
  4. Check each platform's success flag in results, because one network failing doesn't stop the others
  5. Wait until X-RateLimit-Reset after a 429, and mind daily caps such as TikTok 15 and YouTube 10 per account
