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.

OneUp API + MCP

API and MCP on every plan from $25 a month ($15 billed yearly). API key in the query string on REST and in the MCP URL, with no scopes.

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

OneUp API + MCP

  1. Call listcategory, then listcategoryaccount, then schedule. Pass social_network_id as ALL to post to every account in a category
  2. Keep the ?apiKey= URLs out of logs and shared configs, and regenerate the key on the API Access page if one leaks
  3. Set requireApproval or isDraftPost true when a person should review before anything goes out
  4. Page through lists with start, 50 posts at a time
  5. Give dates as YYYY-MM-DD HH:MM with no timezone field, so confirm the account timezone first
