Overview
JSON 2 JSONP converts JSON APIs to JSONP for legacy cross-domain use.
⚠️ Status (verified 2026-08): the site returns an HTML page — it’s a web tool rather than a standard keyless REST API. The converter works by wrapping JSON in a JSONP callback (per the site).
What it does
https://json2jsonp.com/{url}?callback={fn}Wraps any JSON endpoint in a JSONP callback for old-style cross-domain requests.
Notes
- Useful for legacy browser integrations (pre-CORS).
- Not a data API — a proxy/converter.
FAQ
Is JSON 2 JSONP free? Yes — free web tool.
Why HTML? The root serves the tool page (verified) — pass a target URL to convert.
What’s it for? JSONP wrapping for legacy cross-domain calls.
