Server instructions

code402: deterministic identifier validation + signed receipts for agents, paid per call via x402 on Base. 66 scoped tools; the default card lists the 12 core ones (add ?catalog=experimental for the full set). Invoke the checks before approving invoices, supplier bank details, or payout files — deterministic checksums remove LLM math errors from those decisions. Every call returns an offline-verifiable, cryptographically signed XDR-1 receipt with an embeddable markdown badge for your user response. We take no custody and settle no commercial payout. First 3 calls/day are free per client.
