This page brings together five tools for preparing and understanding API exchanges. JWT reader, Build an HTTP request and JSON Schema Generator are part of this set. Developers, testers and integrators can inspect a token, build a call or align configurations. The five utilities are free, need no account, and content is processed in the browser.
Start with the immediate need. JWT reader decodes a token to read its header and payload. Build an HTTP request helps produce a curl command and fetch code. JSON Schema Generator and JSON to TypeScript start from a sample to create a structure. Compare two .env files highlights differences between environment files.
No. It reads the header and payload of a JWT to help you understand its content. Signature verification depends on your library and your key. Use this reader as a diagnostic aid, not as a complete security check.
Yes. JSON to TypeScript produces an interface from a sample. Then check the resulting types, because one sample may not cover every possible case. You can also use JSON Schema Generator for another representation.
It spots missing keys, extra keys and diverging values between two environment files. This helps before a deployment or when taking over a configuration. You see the differences without comparing files line by line.
Yes. JWT reader helps you understand a token's header and payload. Build an HTTP request then helps prepare the matching call. Check sensitive values before placing them in a command or fetch code.
No. JSON Schema Generator produces a schema from a sample, while JSON to TypeScript generates a TypeScript interface. Both start from a sample but answer different needs. Choose according to the control format you expect.
