How do I turn an API into a command-line tool?

Generate the client from a machine-readable spec — OpenAPI, a GraphQL schema, a typed SDK — rather than from prose documentation. A spec-driven generator stays correct when the API changes; a scraped one silently rots.

What to look for

  • 01Does it read a spec or the docs page? Spec-driven output is regenerable; documentation-derived output has to be rewritten by hand each time.
  • 02Does it handle auth, pagination, and errors, or only the happy path? Those three are most of the work in a real client.
  • 03Is the output something you can read and edit, or an opaque runtime you now depend on?

Common questions

Why build a CLI for an API an agent could just call?
A CLI gives the agent a narrow, testable surface with real exit codes and validated arguments, instead of hand-assembled HTTP requests it can get subtly wrong on every call.
What if the API has no OpenAPI spec?
Have an agent write the spec first from the documentation and example responses, review it once, then generate from that. The spec becomes the artifact you maintain.
