## Which one, for what

### bundle.social (C)

Good for: A SaaS product or agent that manages many accounts for many customers, since paid plans do not charge per connected account and teams separate tenants.

Ahead on:
- Schema & documentation, 86 against 46
- Agent ergonomics, 66 against 55
- Payments & pricing, 35 against 15
- Maintenance & community, 78 against 41

Also in its favour:
- Runs on your own machine
- Free to start without a card

Watch for: API keys are organisation-wide with no scopes or read-only mode found, so one key reaches every team and connected account

### Publer API + MCP (D)

Good for: Agencies already on Publer Business who want an agent to schedule in bulk and read deep analytics, including competitors.

Ahead on:
- Security & auth, 41 against 34

Watch for: API and MCP only on Business and Enterprise, and the free plan has no API

## Verdicts

**bundle.social.** The REST API has a public OpenAPI 3.0 description of 194 operations, Markdown docs and published rate limits, and the free plan needs no card. Organisation API keys carry no scopes, there is no idempotency key, and the status page shows one API outage of 4 hours 3 minutes on 31 August 2026.

**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

### bundle.social

1. Send the key in the `x-api-key` header to `https://api.bundle.social/api/v1`. A missing key returns 401 and a bad key 403
2. Pass `teamId` on most calls. Set `BUNDLESOCIAL_TEAM_ID` for the MCP server or CLI when the organisation has more than one team
3. Set a `referenceKey` on each post and look it up with the reference-key endpoint before retrying a create, because there is no idempotency key
4. Check `GET /api/v1/organization/usage/daily-limits` before bulk scheduling. Failed and deleted posts still count against the monthly quota
5. A person must complete each network's OAuth consent in a browser. Keep prepaid credit for X, where a post costs $0.015 or $0.20 with a link

### 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
