ONE ATOMIC JOB

Retrieve less. Verify more.

The relay does the low-cost web work once, then returns only what another agent needs to continue.

  1. 01

    Validate

    Enforce robots policy; reject private networks, unsafe redirects, oversized files, and unsupported content.

  2. 02

    Extract

    Remove interface noise and rank source passages against the caller’s task.

  3. 03

    Prove

    Return source metadata, exact citations, content hashes, and injection warnings.

  4. 04

    Reuse

    Cache only eligible public content so repeated work increases margin.

THE PRODUCT IS THE RECEIPT

Enough evidence to trust—or reject—the result.

Every success exposes what was fetched, how it was transformed, what was omitted, estimated unit economics, and whether the page contained suspicious instructions. Settlement proof arrives in the x402 response header.
