## Verdicts

**Publer API + MCP.** Scoped API keys (workspaces, accounts, posts, media, analytics) with 401 and 403 errors that name the missing scope or header. API and MCP only on Business and Enterprise, and the free plan has no API.

**SocialCannon.** Scoped credentials and published rate limits. X quotas remain on paid plans with unlimited posts.

## Before you call either

### Publer API + MCP

1. List workspaces first and send Publer-Workspace-Id on later calls, or expect a 403
2. Poll /job_status/{job_id} after posts/schedule and read payload.failures, since status reads complete even when posts failed
3. Use the Bearer-API scheme, not Bearer
4. Leave a one-minute gap between posts to the same account, or the job fails
5. Read X-RateLimit-Reset after a 429 and wait until then, as there's no Retry-After

### SocialCannon

1. Use the sandbox before publishing to a real account.
2. Check X quota separately from the general post allowance.
3. Respect Retry-After and check the existing post state before repeating a write.
