JSON → TypeScript

Integrating a third-party API that ships no type definitions usually means hand-writing interfaces from a sample response, and this tool does that step for you, turning a pasted JSON payload into matching TypeScript interfaces including properly nested types for objects and arrays. It's a static-typing tool only: the output gives you compile-time safety and autocomplete, nothing that checks data at runtime, which is the key difference from JSON to Zod. Because it infers everything from a single sample, fields aren't automatically marked optional unless your example happens to show a null, so a second or third example response is worth sanity-checking against the generated interface before you commit it.
