Pill #3 · Just shipped

Paywall any API with one line of HTML.

Drop our x402.js script tag on any page. Every API call from that page becomes pay-per-call USDC on Base 8453. Hive collects 5 bps + per-call receipt fee. The merchant keeps the rest.

Zero backend changes USDC on Base 8453 5 bps Hive clip 60× cheaper than Stripe

The one-line install

<!-- Drop this into <head> -->
<script
  src="https://thehiveryiq.com/cdn/x402.js"
  data-merchant="0xYourBaseAddress"
  data-paths="/api/*"
  data-price-usd="0.01"></script>

That's it. Every fetch() call to a path matching /api/* from this page is now 402-gated. When your backend returns a 402, x402.js triggers a pay flow, settles via Hive's verifier, and retries the original request with an access token.

How the 402 dance works

// Your backend (already done — Hive provides /v1/x402/proof/submit)
// 1. Browser calls /api/expensive-thing
// 2. Backend returns 402 with: {nonce, amount_usd, recipient, chain, asset}
// 3. x402.js prompts the user (or hands off to your CFG.onPay)
// 4. Wallet signs USDC transfer on Base 8453
// 5. x402.js POSTs proof to Hive: {nonce, payer, chain, tx_hash}
// 6. Hive returns {access_token, expires_in_seconds}
// 7. x402.js retries the original request with X-Hive-Access: <token>
// 8. Backend serves the response — you keep 99.5% of the money.

No frontend needed. Three terminal commands and you've completed a full 402 → proof → access cycle against Hive's live production endpoint.

Step 1 — Get a 402 quote

curl -s https://hivemorph.onrender.com/v1/x402/quote \
  -H 'Content-Type: application/json' \
  -d '{"resource":"premium-receipt","amount_usd":0.01}'

# returns: {"nonce":"...", "amount_usd":0.01, "recipient":"0x15184...436E", "chain":"base-8453", "asset":"USDC"}

Step 2 — Send USDC on Base 8453

# From any wallet (Coinbase Wallet, Rabby, Metamask + Base RPC):
# Send 0.01 USDC to 0x15184Bf50B3d3F52b60434f8942b7D52F2eB436E
# USDC contract on Base: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
# Save the tx_hash from your wallet.

Step 3 — Submit proof, get access token

curl -s -X POST https://hivemorph.onrender.com/v1/x402/proof/submit \
  -H 'Content-Type: application/json' \
  -d '{
    "nonce":"<from step 1>",
    "tx_hash":"<from step 2>",
    "payer":"<your wallet address>",
    "chain":"base-8453"
  }'

# returns: {"access_token":"...", "expires_in_seconds":3600, "receipt_id":"..."}

The returned access_token is your gate to the paid resource. The receipt_id is your proof-of-payment, independently verifiable at /verify/ by anyone.

Wallet handoff

Production integrators register an onPay handler that turns the quote into a real wallet signature.

window.HiveX402.onPay = async (quote) => {
  // quote: {amount_usd, merchant, chain, asset, nonce, recipient}
  const tx = await wallet.sendUSDC({
    to: quote.recipient,
    amount: quote.amount_usd,
    chain: 'base-8453'
  });
  return { tx_hash: tx.hash, payer: wallet.address, nonce: quote.nonce };
};
