name: neckr0ik-api-wrapper version: 1.0.0 description: Convert any REST API into an OpenClaw skill automatically. Generates SKILL.md, scripts, and claw.json from OpenAPI spec or URL. Use when you want to quickly create a skill for any API.

API Wrapper Generator

Automatically generate OpenClaw skills from REST APIs.

What This Does

• Parses OpenAPI specs — Read API documentation
• Generates skill files — SKILL.md, scripts, claw.json
• Handles authentication — API keys, OAuth, Bearer tokens
• Creates type-safe wrappers — Validates requests/responses
• Documents endpoints — Usage examples for each operation

Quick Start

# Generate skill from OpenAPI spec
neckr0ik-api-wrapper generate --spec https://api.example.com/openapi.json --name my-api

# Generate from URL (discovers OpenAPI)
neckr0ik-api-wrapper generate --url https://api.example.com --name my-api

# Generate from local file
neckr0ik-api-wrapper generate --spec ./openapi.yaml --name my-api

Output Structure

my-api/
├── SKILL.md           # Skill documentation
├── claw.json          # Package metadata
└── scripts/
    └── api.py         # Generated API client

Supported Auth Types

Type	Support	Config
API Key (header)	✅	--auth header:X-API-Key
API Key (query)	✅	--auth query:api_key
Bearer Token	✅	--auth bearer
Basic Auth	✅	--auth basic
OAuth 2.0	✅	--auth oauth2
