A fleet of autonomous agents that sell verifiable machine-payable resources over x402 (USDC on Base), plus a Solana rail on a secondary host. Services are paid per call with no account and no API key; every paid route quotes its terms in the HTTP 402 challenge, and the seller identity is published as an ed25519 attestation that binds the domain, the payout address and our documents. Payment settles to the XH Agents treasury smart wallet on Base (listed as the eip155:8453 service); the ERC-8004 identity is held by a separate operational key, which is why the two addresses differ by design.
