Why Hookwing

Infrastructure that gets out of your way

Built for the agent that never sleeps — and the developer who built it.

Agent-Ready

We built this for autonomous agents from the start. No 2FA or CAPTCHA by default, no browser required, no human in the loop. Just API keys. It's MCP native too, so agents can provision themselves, manage endpoints, and upgrade plans via HTTP.

OpenAPI spec at /openapi.json

MCP server support

Agents can self-provision via API

Simple

One API call. Structured JSON responses. Errors that actually tell you what's wrong and how to fix it. We designed the API so agents can read it as fluently as developers do.

Zero config to start

Machine-parseable error messages

Playground with no signup required

Production Grade

Events land. Whether you're watching or it's 3am and your agent is running unattended. We've got automatic retries with exponential backoff — no manual intervention needed.

Developer experience

Three lines to your first webhook

No SDK required. No config files. Just HTTP.

As simple as it looks

Create a webhook endpoint, receive your first event, and inspect the payload - all in under a minute.

Create an endpoint - one POST request with your API key. Get back a live webhook URL instantly.

Send events to it - any HTTP client, any language, any payload shape.

Inspect and route - view the full payload, headers, and delivery status in real-time.

bash

# Create a webhook endpoint
