Send a prompt through Realayer and watch it return a model response with a verifiable receipt.

Every successful call returns a response and a receipt with proof status. Payment is requested before the paid AI call runs.

What just happened

Realayer turned one API call into an independently verifiable receipt.

Your prompt was sent to the AI provider and the response came back normally.

Realayer created a fingerprint of the request and the response.

Those fingerprints were cryptographically sealed so the receipt can be verified later.

The proof data and artifacts were stored together as evidence.

For developers

Plug into the gateway.

Use the same chat completions shape you already know. Realayer forwards the call and adds proof metadata around it.
