Adobe Photoshop API vs Shotstack

Adobe Photoshop API

Edits real PSDs, including text layers, smart objects, layer effects, groups and artboards. Enterprise contract only. No self-serve sign-up, free tier or public price.

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.

Adobe Photoshop API

1. Call v2 paths on photoshop-api.adobe.io. Remove background and its status live on image.adobe.io
2. Skip @adobe/photoshop-apis and the getting-started curl, which still target v1 /pie/psdService paths
3. Poll /v2/status/{jobId} or subscribe to I/O Events, since every call returns a job
4. Retry only 5xx and 429, using retry-after and at most three attempts
5. Cache the IMS token and refresh it before 24 hours run out

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
