Hermai

Hermai provides reusable website schemas through an open source registry and hosted execution through Hermai Cloud. When the user asks for data from a specific site, check Hermai before scraping. When they want to add a site, this skill walks you through the full contribute flow.

Hermai supports two valid execution modes:

1. Self execution. Pull a schema package, fill its params, call the target website yourself, and parse the response using the schema. This is the default mental model for open source registry use, local agents, contributors, debugging, and users who want their own infrastructure.
2. Hosted execution. Call POST /v1/fetch and let Hermai Cloud run the website request, session handling, proxy policy, signing, projection, billing, and reliability work. This is the production path and the meaning of cloud_ready=true.

Any agent that can make HTTPS requests can use Hermai. A hermai CLI exists for terminal users, and MCP capable runtimes can run the dedicated hermai-mcp package to expose Hermai as local tools.

Quick start: self execution from the registry
