This facilitator is not taking new merchants right now.

Terms

Terms appear once the facilitator is running.

New merchants are listed as unverified. Verification is a manual check by the site owner, not an audit; changing your name, link or description removes it until checked again, and a merchant can be suspended for abuse. This facilitator has had an internal security review only, not an independent audit.

    settle: { Authorization: `Bearer ${KEY}` },
    supported: {},
  }),
})

official x402 packages
