Provable AI Gateway

Verifiable AI Data

An AI gateway plug-in for verifiable data. Send a prompt. Get response with a content authenticity receipt.

Try a Prompt Find a Receipt

Every call is cryptographically sealed, stored, and independently verifiable.

What just happened

Realayer turned an API call into independently verifiable receipts.

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.

The receipts and artifacts were logged as independently verifiable evidence.

Live Demo

Try it now.

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

For developers

Plug into your AI gateway.

This demo uses chat completions or image generation models. At the gateway, it hashes the request and the response before sending them to cryptowerk.com /register to generate the proof sidecar proof.

The proof sidecar is stored with the request and response data, and the receipt headers maybe returned to the client. You can use those headers to verify the receipt independently at any time in the future.
