Verdicts

Postiz API + MCP

AGPL-3.0 and self-hostable with the API and MCP included, 34 platforms. Create-post capped at 90 requests an hour on every Cloud plan.

Sprout Social API

The API reads analytics, inbox messages, listening topics and cases across the main networks, with OAuth client credentials, field selection and a dated changelog. It creates draft posts only, so a person must publish them in Sprout. Access needs the Advanced plan at $399 per seat a month, and no OpenAPI file or SDK was found.

Before you call either

Postiz API + MCP

  1. Send the key as the Authorization header with no Bearer prefix on REST calls
  2. Batch several posts into one create request to stay under 90 an hour
  3. Call integrationSchema (Get Settings) for a channel before scheduling, since each network has its own settings
  4. Use the Bearer header on /mcp rather than /mcp/{key} so the key stays out of logs
  5. Read output.errors on a failed schedule call and retry with the corrected fields

Sprout Social API

  1. Call GET /v1/metadata/client first for the customer ID, then GET /v1/<customer ID>/metadata/customer for profile and group IDs. Every other path needs them
  2. Send is_draft: true on POST /v1/<customer ID>/publishing/posts. Tell the user the draft waits in the Sprout calendar for a person to publish
  3. Name the fields you want on messages and posts requests. Without the list only guid comes back
  4. Stay under 60 requests a minute and 250,000 a month, and back off on 429 on your own because no Retry-After is documented
  5. Check the response when a draft names several profiles. A profile that cannot take the attached media is dropped with no error
