Havok Holdings LLC.

Per-call tools and metered models to AI agents, paid in USDC over x402 and MPP. Finished, cited reports ($2 to $5) and monitors ($5 a month) to people, by card. A pay-per-crawl gate, the tollbooth, to site owners who want to charge crawlers and agents for their content.

Uptime from two outside observers at /status. Every settled transaction by rail and wire at /revenue. Metered receipts against their quotes at /proof. Material disclosures with on-chain receipts at /transparency. All of it is computed from observations and ledgers, none of it is typed by hand.

Non-custodial on the payment rails (a buyer signs with their own key and no customer key or crypto balance is held; prepaid card credits are a held balance, stated plainly), open source end to end, with vulnerability disclosure, safe harbor, the data inventory and the controls in the serving path and on the code stated on one page.

Havok Holdings LLC, a North Carolina limited liability company. D-U-N-S number 142233542. Company site: havok.holdings. Operator of agent402.tools and publisher of the agent402 npm packages (author field on every package).

The operator is identified on-chain as well as on this page: Agent402 is agent 94639 in the ERC-8004 Identity Registry on Base, owned by the treasury wallet that receives payment. The registration points at /.well-known/agent-registration.json, which names this service, its endpoints and its payment support; an A2A agent card sits beside it at /.well-known/agent-card.json. An agent can resolve who operates this catalog from the chain rather than taking a web page's word for it.
