x402.

Your client signs a USDC transfer to payTo, base64-encodes the proof, and retries with x402-Payment. The gateway verifies on-chain, then forwards your call.

Production-grade x402.

Not a demo. The gateway is live, on mainnet, settling real USDC.

Spec-compliant 402 challenges

Hit any paid Ghola merchant unpaid; you get an HTTP 402 with the standard accepts body — scheme, network, payTo, asset, amount, the works.

Solana mainnet USDC

Settlement happens in USDC on Solana, verified on-chain by the gateway before the upstream call is made.

Replay-protected

Every payment signature is consumed exactly once across the gateway. Burn it twice, get rejected.

Refund on upstream failure

If the merchant's origin times out or 5xxs, the gateway returns 504 with X-Payment-Refund. Your client voids the inbound payment automatically.

Selling? Register your API.

Set a price, point to your origin, and let any x402 client in the world discover and pay you. We handle metering, settlement, and refunds on upstream failure.
