How it works

STEP 1 — Register your API

POST your existing API URL, wallet, and price

curl -X POST https://x402-scoutgate.onrender.com/register \
  -H "Content-Type: application/json" \
  -d '{
    "api_url": "https://your-api.com",
    "wallet_address": "0xYourWalletAddress",
    "price_usd": 0.01,
    "name": "My API",
    "description": "Does something useful"
  }'

STEP 2 — Get your proxy URL

Response includes a ready-to-share proxy URL

{
  "api_id": "abc123",
  "proxy_url": "https://x402-scoutgate.onrender.com/api/abc123",
  "registered_in_catalog": true
}

STEP 3 — Share it

Callers without payment get a 402. Callers with valid USDC authorization on Base get your real response.

# No payment → 402 Payment Required
GET https://x402-scoutgate.onrender.com/api/abc123/endpoint

# With X-PAYMENT header → your API response + on-chain settlement
