Wasmer VPN Proxy (HTTP/HTTPS)

This project provides an application-layer proxy on Wasmer Edge.

Important:

• This is not a full L3/L4 VPN server.
• It is an HTTP/HTTPS forward proxy API (POST /proxy).
• For security, private/local network targets are blocked.

Endpoints

• GET /health
• POST /proxy

Example request:

curl -X POST "https://<your-app>.wasmer.app/proxy" \
  -H "Content-Type: application/json" \
  -H "X-Proxy-Token: <your-token>" \
  -d '{
    "url": "https://httpbin.org/get",
    "method": "GET",
    "headers": {"User-Agent": "wasmer-proxy"}
  }'
