Hermai is a schema registry where developers contribute website API schemas and AI agents consume them. Point an agent at any domain in the registry and get back the full list of callable endpoints — URLs, methods, headers, parameters — ready to execute. No browser, no HTML parsing, no wasted tokens. Think of it as HuggingFace, but for website APIs.

​
How it works

Contribute with the CLI

Use the discovery toolkit (hermai detect, probe, extract, intercept) to document a site’s endpoints, then hermai registry push to add them to the catalog.

Look up from the registry

Call GET /v1/catalog/{domain} to get all known endpoints for a site. The platform serves schemas contributed by the community — instant, structured, no discovery cost.
Using an AI agent? Install the Hermai skills with npx skills add hermai-ai/hermai-skills — Claude Code, Codex, Cursor, and other agents will know how to call the registry and contribute schemas on your behalf.

Quickstart

Sign up, get an API key, and query your first schema in 2 minutes.

How Hermai works

The mental model: contributors discover, agents consume.

Schemas

What schemas are, how to contribute them, and the verified badge.

Catalog

The lookup API that agents call at runtime.

Actions

Read and write actions that schemas expose.

API keys

Authenticate requests and manage access.

​
Open source

The hermai-cli is open source under AGPL-3.0. You can run the full discovery engine locally without an account. The platform registry is the community layer on top — browse, search, and consume schemas that others have contributed.
