openapi2cli（openapi2cli 命令行）

OpenAPI to CLI

Generate command-line tools from OpenAPI/Swagger specs. Perfect for AI agents that need to interact with APIs without writing curl commands.

Quick Start

# generate a CLI from any OpenAPI spec
uvx openapi2cli generate https://api.example.com/openapi.json --output my-api

# use the generated CLI
python my-api.py users list
python my-api.py users get --id 123
python my-api.py posts create --title "Hello" --body "World"

Features

• Auto-generates CLI from OpenAPI 3.x specs
• Supports auth: API keys, Bearer tokens, Basic auth
• Rich help: --help on any command shows params
• JSON output: Structured responses for parsing
• Dry-run mode: See the request without sending

Usage

# from URL
uvx openapi2cli generate https://api.example.com/openapi.json -o my-cli

# from local file  
uvx openapi2cli generate ./spec.yaml -o my-cli

# with base URL override
uvx openapi2cli generate ./spec.json -o my-cli --base-url https://api.prod.com

Generated CLI

# set auth via env
export MY_CLI_API_KEY="sk-..."

# or via flag
python my-cli.py --api-key "sk-..." users list

# see available commands
python my-cli.py --help

# see command options
python my-cli.py users create --help

Example: GitHub API

uvx openapi2cli generate https://raw.githubusercontent.com/github/rest-api-description/main/descriptions/api.github.com/api.github.com.json -o github-cli

python github-cli.py repos list --owner octocat

Why?

AI agents work better with CLIs than raw HTTP:

• Discoverable commands via --help
• Tab completion friendly
• No need to construct JSON payloads
• Easy to chain with pipes
