Why Developers
Choose BlockPay

Built for autonomous, high-frequency finance operations on SUI. The most developer-friendly payment layer for the agentic economy.

Instant Settlement

Transactions settle in ~200ms on SUI. Built for high-frequency finance operations where every millisecond counts. Real-time finality, no batch delays.

Secure by Design

Cryptographically signed payments verified on-chain. No stored credit cards, no chargebacks. Trust-minimized architecture where facilitators can never move unauthorized funds.

Pay as Small as $0.0001

True micropayments finally possible. Charge per API call, per token, per byte. No minimums, no percentage cuts eating your margin.

SUI-Native Performance

Purpose-built on SUI for sub-second finality, minimal gas costs, and parallel transaction execution. Optimized from the ground up for the fastest Move-based blockchain.

Nearly Zero Effort Integration

Add payment gating to any HTTP endpoint with a single middleware on SUI. No accounts, no sessions, no complex auth — just plug in and start accepting autonomous payments.

Transparent & Predictable Fees

No hidden charges, no percentage cuts. Just a small, flat platform fee you can predict before every transaction. Plus nominal blockchain gas fees. What you see is what you pay.

Protocol

How BlockPay Works

Autonomous payments built into HTTP itself. No redirects, no checkout pages — optimized for high-frequency operations on SUI.

1

Request

Client sends a standard HTTP request to a BlockPay-protected resource

2

402 Response

Server responds with HTTP 402 and payment requirements: price, token, network

3

Sign & Pay

Client signs a payment payload and retries with X-PAYMENT header attached

4

Verify & Deliver

Facilitator verifies on-chain, settles instantly, and resource is delivered
