api2cli

A Claude Code skill that turns any API into a working CLI, then wraps that CLI in a skill. Point it at API docs, a live URL, or a peek-api capture and get a dual-mode Commander.js CLI plus a ready-to-use Claude Code skill -- so any future Claude session can pick it up and use it without reading the code.

Requires Claude Code -- this is a skill, not a standalone tool. Claude handles the discovery, generation, and wiring.

What It Does

1. Discovers endpoints from API docs pages, live probing, or peek-api network captures
2. Builds an endpoint catalog with auth, pagination, and rate limit info
3. Generates a CLI with one subcommand per endpoint, a full-featured API client, and dual-mode output (human-readable in terminal, JSON envelope when piped)
4. Generates a skill -- a SKILL.md that teaches Claude how to use the CLI, with commands, examples, and common workflows

Example: Resend API

Here's what it looks like when you point api2cli at the Resend email API.

You say:

Build me a CLI for the Resend API. Here are the docs: https://resend.com/docs/api-reference

Claude discovers 15 endpoints across 5 resources:

Found 15 endpoints across 5 resources:
  emails (3 endpoints): send, get, batch
  domains (4 endpoints): list, get, create, delete
  api-keys (3 endpoints): list, create, delete
  audiences (3 endpoints): list, get, create
  contacts (2 endpoints): list, create
