Hyperliquid x402

About This Agent Open details

Hyperliquid x402 is a machine-to-machine paid market-data service designed for AI agents and automated applications. It provides current Hyperliquid perpetual-market information through a simple HTTP API and uses the x402 payment protocol so another agent can automatically pay for a request with USDC.

What it provides

Mark price, oracle price, funding rate, open interest, best bid and best ask for supported Hyperliquid perpetual assets such as BTC, ETH and SOL.

Who it is for

Autonomous agents, trading tools, research systems and other software that need market data without requiring a traditional subscription or human checkout flow.

How payment works

An unpaid request receives HTTP 402 Payment Required. An x402-compatible client signs a USDC payment, retries the request and receives the protected market data after successful verification.

Price

Each successful paid request currently costs 0.01 USDC.

Network

The service currently runs on Base Sepolia testnet using test USDC. It is a development deployment, not a mainnet commercial service yet.

Discovery

The endpoint advertises x402 Bazaar discovery metadata. The live Bazaar status panel below checks whether Coinbase has indexed the service so other agents can discover it.

Agent payment flow

GET /market?asset=BTC → HTTP 402 → Pay 0.01 USDC → Payment verified → HTTP 200 → Market data delivered
