How it works
Swerver is a reverse proxy with x402 built in.
Swerver sits in front of your origin, speaks x402 to buyers, and forwards paid requests to your existing API.
Keep your API where it is
Point swerver at your upstream URL, add private headers if needed, and set a per-request price.

Agents discover the price
Swerver returns a standards-based payment challenge that x402 clients satisfy automatically.
402 Payment Required
