Start with routes or import an OpenAPI document to build your mock.

Proxy & record a real API Pro

Point the mock at your real API: unmatched calls pass through and real answers are saved as routes. Beeceptor charges $10 a month for its paid plans; this is part of Kivel Pro.

Request conditions & response templates

Match request fieldResponse mode

Templates accept {{path.id}}, {{query.name}}, {{body.name}} and sample data such as {{fake.name}}, {{fake.email}}, {{fake.uuid}}, {{fake.price}} or {{fake.datetime}} inside JSON strings or plain text. Missing values become empty strings. No code runs. Test credentials are stored in the configuration; use fake tokens only.

Response body

Up to 20 routes, 80 KiB total configuration, and 120 requests per minute. Paths support parameters such as /users/:id. Matching routes are checked in order.

About Response builder

Build a temporary HTTP response with a chosen method, path, status, content type, and body. Check that your client reads successful responses and displays errors correctly.

When to use it

Check how a client handles an explicit response body, content type, and HTTP status.

Response builder example

Route: POST /validate
Status: 422
Content-Type: application/json
Body: {"error":"Missing email"}

How to use it

Set an API name and configure your routes.
Create the endpoint and copy its base URL.
Append a route path and send requests from your application.

Limits & privacy

Mock APIs start with a one-hour lifetime; renewal stays within plan limits. Configure up to 20 routes within 80 KiB, delays up to 2 seconds, and 120 requests per minute. Anonymous management requires the private management token; account-owned APIs use workspace access.

Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
