Frequently asked questions

What makes an Image Processing API "agent-friendly"?

For AI coding agents, the highest-impact signals are: an official SDK on npm or PyPI, environment variable authentication (no browser OAuth flow), JSON responses that parse cleanly, machine-readable pricing, and reasonable rate limits for scripted use. APIs missing more than two of these are painful for agents to use reliably.

How do you score Image Processing APIs?

Each API is rated on 8 signals worth 1-2 points each (11 raw, normalised to 10). The full rubric: official SDK (+2), env var auth (+2), headless compatible (+2), CLI tool (+1), JSON response (+1), curl/CLI docs examples (+1), reasonable rate limits (+1), machine-readable pricing (+1). The top-scoring API in this category right now is Cloudinary Image at null/10.
