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.\n\n## Before you call either\n\n### Buffer API + MCP\n\n1. Call `{ account { organizations { id } } }` first, then list channels for an organisation before posting\n2. Include `... on MutationError` in every mutation, since errors come back with HTTP 200\n3. On 429, wait Retry-After plus a few seconds of jitter. The 429 itself doesn't cost quota\n4. Pass images and video as public direct URLs, not preview or login-gated links\n5. Use saveToDraft or addToQueue so nothing publishes by accident, because delete_post can't be undone\n\n### bundle.social\n\n1. 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\n2. Pass `teamId` on most calls. Set `BUNDLESOCIAL_TEAM_ID` for the MCP server or CLI when the organisation has more than one team\n3. 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\n4. Check `GET /api/v1/organization/usage/daily-limits` before bulk scheduling. Failed and deleted posts still count against the monthly quota\n5. 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\n\n## Questions\n\n### Which is better for AI agents, Buffer API + MCP or bundle.social?\n\nBuffer API + MCP scores 62 (B) on agent readiness against bundle.social's 60.1 (C), and leads in 2 of 7 scored categories. bundle.social leads on reliability, payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Buffer API + MCP and bundle.social need an API key?\n\nBuffer API + MCP takes an API key or an OAuth sign-in. bundle.social needs an API key.\n\n### Can an agent call Buffer API + MCP and bundle.social without installing anything?\n\nYes. Buffer API + MCP has a hosted endpoint at https://api.buffer.com and bundle.social at https://api.bundle.social/api/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/buffer-vs-bundle-social.json, and with the fewest tokens: https://www.anchorterminal.com/compare/buffer-vs-bundle-social.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"buffer\", \"b\": \"bundle-social\"}`.
