# Aleva

> Aleva collects Swedish public data (registries, statistics, the .se and .nu domains, transport, energy,
> courts, prices and more), records the licence of every source, and publishes the data as a JSON API and
> as tools over the Model Context Protocol. Every answer says where the data comes from, when it was
> fetched and how it may be used.

## Agent surface

- [MCP server](https://api.aleva.se/mcp): streamable HTTP, stateless, read-only, no account needed; an API key in Authorization: Bearer raises the limits
- [MCP server card](https://api.aleva.se/mcp/server-card)
- [REST API](https://api.aleva.se): GET requests, JSON responses with _meta (source, licence, fetch time)
- [OpenAPI description](https://api.aleva.se/openapi.json)
- [Registry of every endpoint](https://api.aleva.se/v1/_registry): paths, parameters, licences, freshness
- [API documentation](https://aleva.se/en/docs)
- [MCP documentation](https://aleva.se/en/docs/mcp)
- [API catalog](https://aleva.se/.well-known/api-catalog): RFC 9727 linkset

## Using the data

- Show the attribution that comes with the data (`_meta.license.attribution`, or the X-Attribution header).
- Anonymous use is free within low limits per IP address; the limits are in the registry. 429 means wait for Retry-After.
- Results are paged: follow next_cursor.
- Everything is read-only. Nothing on Aleva takes payment or changes data.
