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
