Mock JSON API Builder

Generate a realistic JSON API response: a paginated list of fake records with metadata (total, page, next, prev cursors) and HTTP-style headers (ETag, Cache-Control, X-Request-ID). Useful for seeding test fixtures, populating a mock server, or designing API responses.

How to use the Mock JSON API Builder

Pick number of records, page size, response style, and record shape. Generate produces a realistic JSON document plus a sample header set you'd return alongside it. Use the JSON to seed a test database or feed a mock server (json-server, msw, mockoon).
