Use cases
Your agent reads the sites that matter.
Government records, business filings, procurement, and live market data, delivered through structured, site-specific interfaces instead of page markup.
Benchmarks
Complete data. Fewer tokens.
Real workflows on government and consumer sites where generic scrapers come back empty. Benchmarked against Firecrawl and WebFetch on what each tool actually returned: records, structured fields, and the tokens to parse them.

Request a source
Need a site we don't cover yet?
We stand up new sources for customers. Tell us the site and the data you need and we will come back with a plan.
How it works
Install once. Ask anything. Get structured data.
No scrapers. No HTML parsing. No guessing. Your agent reads schemas, calls the site, and hands you clean data from the registry.
Install the skill
Run the install command in any agent. Claude Code, Cursor, Windsurf, and 40+ tools.

Ask anything
Your agent reads the schema, calls the real API, and handles auth. No scraping, no guessing.

Get structured data
Clean structured data, not HTML noise. Schemas discovered once, reused whenever you need the same site data.

Hermai is an open catalog of website APIs. Anyone can add a schema with the CLI; every contribution makes the next agent more reliable. AGPL-3.0.
Using Claude Code, Cursor, or Codex? Add the hermai skill and let your agent run the CLI for you, with schema rules enforced. The contributor references load on demand.

FAQ
Frequently asked questions
Short answers about the catalog, schemas, and how Hermai helps teams use stable website APIs.
What is Hermai?
Hermai is an open catalog of website APIs. Contributors add schemas for sites that do not offer a clean public API, so products and agents can use stable data instead of brittle scrapers.
How is this different from web scraping?
Scrapers depend on page HTML, so they break when a site changes its layout. Hermai schemas describe the API surface behind a site and return structured JSON.
Is Hermai free to use?
Yes. The schema catalog, CLI, and HTTP API are open source under AGPL-3.0. You can browse schemas and try the playground without signing up.
What sites does Hermai support?
The catalog covers commerce, media, travel, finance, government, developer tools, and more. Check the live catalog to see what is covered today.
Can I use Hermai for government and public-record data?
Yes. Government and public records are a flagship vertical: federal registers, procurement, and state and local open-data portals as structured APIs. Each catalog entry shows its published availability and verification signals. See the Government solutions page for current coverage.
How do I add a new schema?
Install the CLI, inspect a site's API surface, then publish the schema to the registry. The hermai skill can guide your agent through the process.
Who maintains the schemas?
Schemas are contributed and maintained by the community. Catalog entries publish availability and verification metadata where it has been established, and that coverage is still expanding.
