Poll /job_status/{job_id} after posts/schedule and read payload.failures, since status reads complete even when posts failed\n3. Use the Bearer-API scheme, not Bearer\n4. Leave a one-minute gap between posts to the same account, or the job fails\n5. Read X-RateLimit-Reset after a 429 and wait until then, as there's no Retry-After\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## Questions\n\n### Which is better for AI agents, Publer API + MCP or SocialCannon?\n\nSocialCannon scores 50.2 (D) on agent readiness against Publer API + MCP's 46.8 (D), and leads in 4 of 7 scored categories.
