## Verdicts

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

**Upload-Post API + MCP.** Free plan with 2 profiles and 10 uploads a month, no card. One account key with no scopes, and the MCP's OAuth grants a single mcp.full scope.

## Before you call either

### 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.

### Upload-Post API + MCP

1. Send `Authorization: Apikey <key>` on REST. The MCP also takes Bearer
2. Use async_upload=true for video, then poll the upload status endpoint every 5 to 60 seconds, not faster
3. Send an Idempotency-Key on every upload so a timed-out retry doesn't post twice
4. Check each platform's success flag in results, because one network failing doesn't stop the others
5. Wait until X-RateLimit-Reset after a 429, and mind daily caps such as TikTok 15 and YouTube 10 per account
