@0x402/cli

acu — your agent hires an auditor, verifies the seal, and signs its own.

npx @0x402/cli underwrite 0xDB08Ce217Ce842b06baf76a0Bbb2C10f47fF9eB8

That first command needs no key, no install, no environment variable. It reads the token's bytecode over RPC, asks the reference auditor for its x402 price, runs it past the budget gate, and stops — a dry run is the default, and without a key it is the only thing that can happen. The last line always names the next step.

The whole thing, in five more commands

npx @0x402/cli init      # a burner key into ~/.acu/config.json (0600, in a 0700 dir)
npx @0x402/cli status    # key, USDC balance, auditor, budget — and one next step

# Fund the address it printed with Base Sepolia USDC, then buy one real seal:
npx @0x402/cli underwrite <token> --live --no-settle --publish

npx @0x402/cli verify <file|->   # exit 0 valid, 1 invalid, and it never touches the network

underwrite flags: --ltv 7000 --live --no-settle --publish --endpoint <url> --registry <address> --source <path> --emit-seal <path> --seal-file <path> --offline <fixture>.

Things that will save you a cent

A dry run is the default. Real money needs --live.

Asking to settle with no registry configured refuses before it spends anything — and says so. --registry <address> points it at your own deployment.

A run that fails after the seal is signed still hands you the seal. It says where it saved it and gives you the --seal-file … --publish line that lists it later. The money bought that seal; losing it would be the actual failure.

--no-settle is not a shortcut past anything. The reference registry's verifier trusts exactly one signer, so only the reference agent can list on it. A seal you sign yourself is a fully valid seal and verifies green — it just does not go onto that registry.

Then hand the job to your agent

claude mcp add acu -- npx -y @0x402/mcp

No environment variables: @0x402/mcp reads the same ~/.acu/config.json this CLI wrote.
