General protocol translator

Machines pay
machines.

WireSwitch translates between payment protocols so an agent can pay a merchant that doesn't speak the same language. Sign locally. Hop once. We settle the rail you name.

Issue a test key npm i wireswitch

AP2 and x402 in. Stripe and x402 out. One hosted hop.

Agent signs locally

Ed25519 on the device. Spend caps before anything is sent.

Name the pair

ingressProtocol and egressProtocol on one POST to /v1/translate.

We settle the merchant rail

Stripe PaymentIntent or Coinbase x402. Same hop, same signed envelope.
