## Verdicts

**Blotato.** One paid account gives an agent a REST API with a public OpenAPI document and an MCP server with 36 tools, with request limits and error codes documented in detail. No status page, changelog, security contact or free API access was found, and each account has a single key with full access.

**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.

## Before you call either

### Blotato

1. Call `blotato_list_accounts` or `GET /v2/users/me/accounts` first, and fetch `pageId` or `boardId` before posting to a Facebook Page, LinkedIn company Page or Pinterest
2. Keep the `postSubmissionId` and poll the status until `published`, `scheduled` or `failed`. It is a receipt, not proof of publication
3. After a timeout on a create call, list existing posts before sending again, because there is no idempotency key
4. Do not generate an API key on a trial account unless the owner accepts the Starter charge
5. Keep REST bodies and MCP arguments apart. REST nests `post.content` and `post.target`, and the MCP tool takes flat arguments

### 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
