Payment Intent Preview

Paid retry command

Copy-paste only from a buyer-controlled wallet runtime

The command uses a minimal four-field template so the route, price, max amount, and retry shape are visible immediately. Replace the sample JSON with your own service details before payment, or use the free Builder until it returns ready_to_pay.

npx awal@2.8.0 x402 pay "https://agent-research-brief-api-production.up.railway.app/api/agent-revenue-audit" \
  -X POST \
  -h '{"Content-Type":"application/json"}' \
  -d '{
  "serviceName": "Example Agent API",
  "buyerType": "x402-builder",
  "currentOffer": "A pay-per-call endpoint that helps agents decide what paid route to buy first.",
  "currentPaymentRail": "base-x402",
  "targetBuyer": "Agent and API builders trying to monetize faster.",
  "currentProblem": "Buyers hit the 402 challenge but do not always understand the exact paid retry path.",

  --max-amount 5000000 \
  --json

Fastest safe $5 path

One paid retry after buyer approval.

1. Confirm this route matches the buyer's current problem.
2. Use the shown max amount and Base x402 network.
3. Replace the sample fields if this is a real buyer request.
4. Run the paid retry only from a buyer-controlled wallet runtime.
