No status page, security contact or idempotency key was found, and the privacy policy contradicts the vendor's no-training statement.\n\n**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.\n\n## Before you call either\n\n### PostNitro\n\n1. Call `postnitro_set_defaults` once with a template, brand and AI preset, or every generate call must carry those IDs\n2. Pass the `designId` from `postnitro_get_output` to scheduling, never the `embedPostId`, or the call fails with `Design not found`\n3. For a LinkedIn PDF post, set `linkedinPostSettings.postType` to `document` with a 5 to 90 character `postTitle`\n4. Ask for the `DESIGN` output or save as `DRAFT` when a person must approve before anything publishes\n5. Keep to 5 create calls a minute per key and wait for `Retry-After` on a 429\n\n### Shotstack\n\n1. 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\n2. Render in `stage` first. It is free and watermarked, but AI generation there is charged from the production credit balance\n3. 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\n4. 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\n5. 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\n\n## Questions\n\n### Which is better for AI agents, PostNitro or Shotstack?\n\nShotstack scores 65.3 (B) on agent readiness against PostNitro's 44.5 (E), and leads in every scored category.\n\n### Do PostNitro and Shotstack need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call PostNitro and Shotstack without installing anything?\n\nYes.
