An AML check your agent can pay for, by itself

Most APIs assume a human signed up, accepted terms, and put a credit card on file. Agents don't do that. So we expose the same risk-scoring engine over MCP — discoverable, callable, and billable per request via x402 micropayments. No keys, no signup, $0.40 / call.

x402 — pay per call, no account

x402 is HTTP 402 Payment Required, finally implemented. Server returns a price, agent settles in USDC, request resumes. We never know who you are; you don't have to log in.

▸ USDC on Base · settles in <1s
▸ No API keys, no rate limits beyond what you pay for
▸ Idempotent — same payment proof = same response
▸ Receipts on-chain, queryable by anyone

// flow.txt client ⇄ server

# agent_prompts.txt — copy/paste

What you'd actually ask an agent

// compliance officer

"Before you draft the SAR, check 0x8589…DA16 with daoaml and paste the verdict link in the report."

// OTC trader

"For every counterparty in this CSV, run daoaml check. Flag anything HIGH or CRITICAL and don't initiate the trade."

// solidity dev

"Before signing this transaction, call daoaml on the recipient address. If score > 60, abort and tell me why."

Hand it to your agent

Three calls a day are on us. Past that, $0.40 per check, paid from the agent's own wallet. No middleman.
