Verdicts

OneUp API + MCP

API and MCP on every plan from $25 a month ($15 billed yearly). API key in the query string on REST and in the MCP URL, with no scopes.

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.

Before you call either

OneUp API + MCP

  1. Call listcategory, then listcategoryaccount, then schedule. Pass social_network_id as ALL to post to every account in a category
  2. Keep the ?apiKey= URLs out of logs and shared configs, and regenerate the key on the API Access page if one leaks
  3. Set requireApproval or isDraftPost true when a person should review before anything goes out
  4. Page through lists with start, 50 posts at a time
  5. Give dates as YYYY-MM-DD HH:MM with no timezone field, so confirm the account timezone first

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
