Instant Settlement

Payments settle on Robinhood Chain in seconds via EIP-3009 transferWithAuthorization. No waiting, no escrow.

No Gas Fees

Users sign an off-chain authorization. The facilitator pays gas and settles on-chain. Your users never touch ETH.

No API Keys

Forget signups, credentials, and monthly plans. Pay per request with USDG. The payment IS your authentication.

One Line to Integrate

Drop hg.gate() into any Express route. The 402 handshake is fully automated.

Micro-Priced

Charge 0.5 USDG per call — or any amount. Perfect for pay-as-you-go APIs, data feeds, and AI agents.

Integration

      import { hoodgate } from "hoodgate";
       
      // Configure your toll gate
      const hg = hoodgate({
      price: "0.5", // USDG
      network: "eip155:46630", // Robinhood Chain
      token: "USDG",
      });
       
      // Protect any endpoint
      app.post("/weather", hg.gate(), handler);
      // ← 402 Payment Required → 200 OK with data

FAQ

What is HTTP 402?

402 Payment Required is a reserved HTTP status code from the original spec, unused for decades. x402 revives it: the server replies 402 with payment terms, the client pays, and retries. hoodgate implements this on Robinhood Chain.

Do my users need ETH for gas?

No. Users sign an EIP-3009 authorization off-chain — a gasless signature. The facilitator submits the transaction and pays gas. Users only need USDG.

Is this custodial?

No. The EIP-3009 signature authorizes exactly one transfer of a fixed amount to a fixed recipient. hoodgate never holds user funds and cannot move more than authorized.

Can I self-host the facilitator?

Yes. The facilitator is open source. Run your own, point hoodgate at it, and use any EIP-3009 token you like. No dependency on our infrastructure.
