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.

Photoroom API

A call costs $0.02 for background removal or $0.10 for any combination of edits, and a sandbox key gives 1,000 free watermarked calls a month without a card. No status page or official SDK was found, and Photoroom's privacy policy and security page disagree on whether API images train its models.

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

Photoroom API

  1. Send the key in the x-api-key header. Prefix it with sandbox_ while testing, because calls with the plain key consume paid images
  2. Save the response body as a file. A 200 returns image bytes, PNG by default, and any other status returns JSON with error.message or detail
  3. Send model selectors such as pr-ai-shadows-model-version: 2026-04-15 as HTTP headers, not form fields. They are not in the OpenAPI file
  4. Stay under 60 images a minute. On 429 back off with an exponential delay, and set a client timeout of at least 60 seconds for AI edits
  5. Use POST /v2/edit with imageFile for local files and GET /v2/edit with imageUrl for hosted ones. Each call takes one image
