El Catastro español, en JSON limpio.
Summary
PredioHQ offers a JSON-friendly wrapper around Spain's cadastre API, replacing SOAP/XML with a REST/MCP-based interface and a versioned JSON output. The product provides multiple ways to resolve property data (by reference, coordinates, or address), an OpenAPI spec, a machine-readable llms.txt, and a free tier for testing, emphasizing ease of integration for proptech and IA agents. It also notes licensing and that the data comes from the public Catastro source, with caveats about accuracy and official status.
