Developer Tools

Standalone utilities for debugging HTTP, generating test data, and spinning up mocks quickly.

HTTP echo

Mirrors your request method, headers, query, and body — useful for debugging clients and proxies.

curl -X POST https://www.mockapibuilder.io/api/echo?foo=bar \
  -H "Content-Type: application/json" \
  -d '{"hello":"world"}'

Test data generator

UI at /tools/generate — export JSON, CSV, or SQL from a schema.

curl -X POST https://www.mockapibuilder.io/api/tools/generate \
  -H "Content-Type: application/json" \
  -d '{"fields":{"id":"number","name":"string"},"count":5,"format":"json"}'

Paste-to-mock

Paste JSON or XML at /tools/quick-mock to create a project and endpoint instantly. Requires login.

curl -X POST https://www.mockapibuilder.io/api/projects/quick-mock \
  -H "Authorization: Bearer YOUR_JWT" \
  -H "Content-Type: application/json" \
  -d '{"name":"My API","body":{"users":[{"id":1}]}}'

2FA TOTP generator

Generate time-based one-time codes at /tools/2fa.

curl -X POST https://www.mockapibuilder.io/api/tools/totp \
  -H "Content-Type: application/json" \
  -d '{"secret":"JBSWY3DPEHPK3PXP"}'

Local tunnel

Expose a mock running on your machine through a public URL — open the Import menu on a project page and choose Local Tunnel.

It gives you a public URL, the CLI command to run locally to open the tunnel, an auth token, and an expiry time — handy for sharing a work-in-progress mock or testing a webhook callback against your machine.
