X quotas remain on paid plans with unlimited posts.\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### SocialCannon\n\n1. Use the sandbox before publishing to a real account.\n2. Check X quota separately from the general post allowance.\n3. Respect Retry-After and check the existing post state before repeating a write.\n\n## Tutorials\n\n- [Prepare a channel draft with Buffer](https://www.anchorterminal.com/tutorials/buffer/), for Buffer API + MCP\n\n## Questions\n\n### Which is better for AI agents, Buffer API + MCP or SocialCannon?\n\nBuffer API + MCP scores 62 (B) on agent readiness against SocialCannon's 50.2 (D), and leads in 4 of 7 scored categories.
