## Which one, for what

### Postiz API + MCP (C)

Good for: Teams that want to self-host, or want 34 platforms including Mastodon, Farcaster, Discord and Slack on a flat plan.

Ahead on:
- Schema & documentation, 88 against 51
- Agent ergonomics, 65 against 59
- Payments & pricing, 30 against 20
- Maintenance & community, 85 against 38
- Transparency & trust, 81 against 70

Also in its favour:
- Open source

Watch for: Create-post capped at 90 requests an hour on every Cloud plan

### Sprout Social API (C)

Good for: Reporting agents that pull profile, post, inbox, listening and case data for a company that already pays for Sprout Social, and for drafting posts a person will approve.

Ahead on:
- Reliability, 71 against 53
- Security & auth, 61 against 49

Also in its favour:
- No incidents deducted, where Postiz API + MCP loses 3 points for them

Watch for: Posts can be created only as drafts (`is_draft: true`), so the API cannot publish or schedule a post without a person in Sprout

## 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
