## Which one, for what

### Canva REST APIs + MCP (B)

Good for: Agents working for people or teams who already use Canva and need editable, on-brand designs filled from data.

Ahead on:
- Schema & documentation, 95 against 88
- Security & auth, 63 against 48
- Maintenance & community, 85 against 73
- Transparency & trust, 83 against 73

Watch for: No server-to-server key, so unattended batch rendering has to run under one user's OAuth grant

### 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 64
- Payments & pricing, 45 against 30

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

**Canva REST APIs + MCP.** OpenAPI 3.0 with 59 described operations, per-user rate limits and a 78-value error code enum. No server-to-server key, so unattended batch rendering has to run under one user's OAuth grant.

**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

### Canva REST APIs + MCP

1. Call the user capabilities endpoint before autofill, brand templates or resize, which need Pro or above
2. Poll export, upload and autofill jobs with exponential backoff and download results within 24 hours
3. Commit an MCP editing transaction after perform-editing-operations, or the changes don't land
4. Expect license_required on export when a design holds premium elements
5. Read `page_number`, not the deprecated `index`, from Get design pages

### 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
