APITemplate.io vs Pexels

APITemplate.io lets teams design reusable HTML or drag-and-drop templates in a browser editor, then render them into images or PDFs on demand through a REST call, Zapier, Make, or n8n. Requests send JSON overrides for named text, image, and color elements (with Jinja2 available for PDF templating) and get back a hosted download URL for the generated PNG or PDF. A free plan covers 50 image/PDF renders and 3 templates a month, with paid PDF and image plans scaling to tens of thousands of documents.

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.
