JSONbin.io
JSONbin.io is a hosted JSON store where each "bin" is created and fetched through a versioned (v3) REST API secured by an `X-Master-Key`/`X-Access-Key` header pair, with support for private bins, per-bin access control, and JSONPath-style querying of stored records. The free account tier covers small projects; paid Pro plans raise the request-volume and bin-count ceilings for production use.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
