x402r CLI

You help users make escrow payments and file payment disputes on the x402r protocol. The x402r protocol adds refundable payments to HTTP 402 — buyers can request refunds through on-chain arbitration.

Setup

npx --yes @x402r/cli config --key <private-key> --arbiter-url https://www.moltarbiter.com/arbiter

Operator, network, and RPC are auto-discovered from the arbiter. The wallet needs Base Sepolia ETH (gas) and USDC (payments).

Test merchant: https://fantastic-optimism-production-602a.up.railway.app/weather

Commands

pay

npx --yes @x402r/cli pay <url>
npx --yes @x402r/cli pay <url> --output response.json

Makes an escrow payment. Saves payment info to ~/.x402r/last-payment.json for later dispute.

dispute

npx --yes @x402r/cli dispute "reason" --evidence "details"

Creates on-chain refund request + submits evidence in one step. Uses saved payment info from pay. Prints a dashboard link.

Options: -e/--evidence <text>, -f/--file <path>, -p/--payment-json <json>, -n/--nonce <n>, -a/--amount <n>

status

npx --yes @x402r/cli status

Check dispute status. Tries arbiter API first, falls back to on-chain. Options: --id <compositeKey>, -p/--payment-json, -n/--nonce

show

npx --yes @x402r/cli show

Show all evidence (payer, merchant, arbiter) for a dispute. Options: -p/--payment-json, -n/--nonce

verify

npx --yes @x402r/cli verify

Replay the arbiter's AI evaluation to verify the commitment hash is deterministic. Options: -p/--payment-json, -n/--nonce

list

npx --yes @x402r/cli list

List disputes from the arbiter. Options: -r/--receiver <addr>, --offset <n>, --count <n>

Typical Workflow

  1. npx --yes @x402r/cli pay <merchant-url> — escrow payment, saves state
  2. npx --yes @x402r/cli dispute "reason" --evidence "details" — files dispute
  3. npx --yes @x402r/cli status — check arbiter ruling
  4. npx --yes @x402r/cli show — view evidence from all parties
  5. npx --yes @x402r/cli verify — verify ruling was deterministic

Notes

  • State chains between commands: pay saves for dispute, dispute saves for status/show/verify.
  • Without saved state, pass --payment-json and --nonce explicitly.
  • verify requires the arbiter server — no on-chain fallback.
