Two rows for the Extensions table, both published on npm and live:

  • agent402-tollbooth: a pay-per-crawl gate for Node/Express sites. One middleware answers an MPP WWW-Authenticate: Payment challenge (evm/charge and tempo/charge) and x402 on the same 402, translates inbound Authorization: Payment credentials for the operator's settlement middleware (so settlement authority stays with one component), mirrors Payment-Receipt on success, and adds a proof-of-work free tier, charge modes, and a stats dashboard. The MPP codec is dependency-free and its challenge id binding is compatible with mppx's Challenge.verify.
  • agent402-client: a buyer SDK for agents: find() a paid endpoint, call() it, and pay the 402 automatically over MPP (Authorization: Payment) or x402 from the agent's own key, with response caching, idempotent retries, and spend caps. Non-custodial.

Links point at npm and the package directories in the source repo.

@MikeyPetrillo is attempting to deploy a commit to the Tempo Team on Vercel.

A member of the Team first needs to authorize it.
