Trip Planner Proxy

A Cloudflare Worker that proxies geocoding and routing requests to OpenStreetMap services with proper headers and simplified responses.

What It Does

Provides 4 endpoints that forward requests to free mapping APIs:

• /geocode/search - Search for locations (powered by Nominatim)
• /geocode/reverse - Get address from coordinates (powered by Nominatim)
• /route - Calculate route between waypoints (powered by OSRM)
• /table - Calculate distance/duration matrix (powered by OSRM)

The proxy adds required User-Agent headers and contact emails to comply with OpenStreetMap usage policies, and normalizes responses to a consistent JSON format.
