## Which one, for what

### Placid API + MCP (E)

Good for: Small teams and no-code builders who want template renders to image, PDF and video at a low monthly price, and agents that should be fenced to a few templates.

Also in its favour:
- No incidents deducted, where Shotstack loses 3 points for them

Watch for: No OpenAPI, no llms.txt, and the MCP tool list isn't published

### Shotstack (B)

Good for: Teams that render video, images or audio from JSON or templates at volume and want an agent to draft edits that a person reviews in Studio.

Ahead on:
- Reliability, 85 against 75
- Schema & documentation, 88 against 34
- Agent ergonomics, 63 against 40
- Security & auth, 48 against 34
- Payments & pricing, 45 against 35
- Maintenance & community, 73 against 7
- Transparency & trust, 73 against 57

Watch for: API keys have no scopes. One production key and one sandbox key reach the Edit, Serve and Ingest APIs, and key rotation was not found in the docs

## Verdicts

**Placid API + MCP.** Hyperping status page with separate App and API components and 90-day history. No OpenAPI, no llms.txt, and the MCP tool list isn't published.

**Shotstack.** A public OpenAPI definition, Markdown docs, a hosted MCP server with OAuth and a free watermarked sandbox let an agent draft, check and render video with little setup. API keys have no scopes, webhooks are unsigned, no security contact or certification of Shotstack's own was found, and the published Node and Python SDKs date from July 2024.

## Before you call either

### Placid API + MCP

1. Send the token in the `Authorization` header, not as ?api_token=, wherever the client allows it
2. Read X-RateLimit-Remaining and wait for X-RateLimit-Reset after a 429
3. Use test mode for watermarked previews while matching layer names, then switch to live renders
4. Leave create_now off for batches, since it caps at 10 at once and may fail under load
5. Poll the returned polling_url or pass webhook_success, since images start as queued

### Shotstack

1. Fetch `https://shotstack.io/docs/api/api.edit.json` and the conventions guide before writing an edit. Track order is reversed, so the first track renders on top
2. Render in `stage` first. It is free and watermarked, but AI generation there is charged from the production credit balance
3. Call `POST /generate/quote` before `POST /generate`, and send an `Idempotency-Key` header on generation. `POST /render` has no idempotency key, so do not resubmit blindly
4. Do not store the `url` from the render status response. It expires after 24 hours. Use the CDN address built from `owner` and the render id
5. On a 429, wait for the 60-second window to reset and retry with backoff. Limits are per API key, 300 a minute on the Edit API in production
