PSGC Cloud

Developers, researchers, web designers, and institutions often struggle to turn Philippine Standard Geographic Code data into clean, dependable application data. PSGC Cloud provides a free, public REST API for querying Philippine regions, provinces, cities, municipalities, sub-municipalities, and barangays in structured JSON.

The service supports versioned API documentation for v1 and v2, direct resource lookups, nested hierarchy traversal, ancestry validation, predictable fields, cached responses, and lightweight read-only endpoints. Developers can use standard HTTP clients, with examples for cURL, JavaScript fetch, Axios, and PHP Guzzle.

PSGC Cloud also includes a live Model Context Protocol server with geographic query tools for AI clients and coding environments, including Claude Desktop, Cursor, Antigravity IDE, and VS Code extensions such as Cline and Roo-Code. The API is community-provided and mirrors PSGC geographic structures; critical boundaries should be independently verified.
