Transparent proxy
A proxy that forwards a request to the upstream provider without altering its behavior or revealing itself, so the provider sees ordinary traffic and the buyer gets the genuine response.
A transparent proxy stands between a buyer and an upstream API and forwards requests without changing what the buyer asked for or fingerprinting the traffic for the provider. The buyer calls the proxy as if it were the API; the proxy relays the call upstream, returns the genuine response, and stays out of the way. "Transparent" means the proxy does not leak its own identity to the provider and does not distort the buyer's request or the provider's answer.
Proxygate's gateway is a transparent proxy that adds metering, payment, and security around an unchanged passthrough. It strips internal routing parameters and upstream credentials so the provider cannot tell the call came through Proxygate, allowlists which response headers pass back, and injects the seller's key server-side. Streaming responses pass through, and the buyer receives the real upstream body along with the exact amount charged and a signed receipt.
Transparency protects both sides. Providers see normal API traffic and cannot single out or rate-limit Proxygate buyers as a class, which preserves the value of the resold capacity. Buyers get the authentic response, not a rewritten one, so they can trust the data. The proxy's additions, metering, key injection, and optional response scanning, sit alongside the passthrough rather than altering the payload.

A transparent proxy forwards a buyer's request to an upstream API without altering the request or response and without revealing itself to the provider. The buyer gets the genuine upstream response as if it had called the API directly.
The gateway strips internal routing parameters and upstream credentials, allowlists response headers, and injects the seller key server-side, so the provider sees ordinary traffic and the buyer receives the real upstream body with a signed receipt.
It keeps providers from singling out or rate-limiting marketplace traffic as a class, which preserves the resold capacity, and it guarantees buyers receive the authentic response rather than a rewritten one.
