# Istruzione Messina developer documentation

A free public date-based angel-number calculation. No account or API key is required.

- [Public API reference](https://istruzionemessina.it/docs/public-api)
- [MCP server](https://istruzionemessina.it/docs/mcp)
- [OpenAPI JSON](https://istruzionemessina.it/docs/openapi.json)

The API returns a digit-root number for the submitted date, not a personalized reading. The separate public-content MCP connector and its authenticated `/mcp/connect` endpoint are documented on the MCP page.
