Pexels vs PhotoRoom

Pexels' JSON API serves its library of free stock photos and videos for keyword search, curated collections, and per-item lookups, with photo results carrying several pre-generated JPEG sizes ready to use without further processing. A personal key sent via the Authorization header is the only credential required — no OAuth flow — and a live probe of the search endpoint showed a 25,000-request rate-limit window tracked per key rather than per IP. There is no paid tier: under the Pexels License, images and videos are free for personal and commercial use, with attribution appreciated but not required.

PhotoRoom's API takes a product or portrait photo and returns a background-removed, background-generated, or otherwise edited image via a single multipart POST, authenticated with an x-api-key header per its docs at docs.photoroom.com — a separate GitBook site from the marketing homepage. A live CORS preflight against its segmentation endpoint reflected two different arbitrary Origin headers back with credentials enabled, so browser-side calls are supported directly. New accounts get a 1,000-image sandbox allowance for testing plus limited free production calls to the Remove Background endpoint, with paid plans covering higher volume and the full Image Editing API.
