Paste JSON.
Get an endpoint.
SuperBins serves your JSON from a permanent URL — with control over status codes, latency, and conditional responses. No servers, no deploys.
Free tier available. No credit card required.
GET /api/b/:id
A real endpoint, not a paste
Every bin lives at a permanent URL and answers with proper JSON. Point your app, webhook, or test suite at it and it just responds.
- —Live the moment you save
- —Clean, permanent URLs you can share
- —Public or private, per bin

Shape every response
Build rules in a visual editor: match on methods, headers, or query params, then change the status code, add latency, or swap the whole body. Test the unhappy paths without writing a server.
- —Conditions on any part of the request
- —Simulate slow networks and error codes
- —No code required — it's all point and click
