Your AI agent can now read DeFi markets. Track profitable wallets, detect insider patterns, and analyze capital flows across Polymarket, Hyperliquid, and Meteora with a single API. Pay per query with USDC on Solana. No API keys, no accounts, no onboarding, no gas fees. Payment is authentication.

​
What You’ll Access

How x402 Payment Works

1

Send Your Request

Call any endpoint. The server responds with HTTP 402 and the exact USDC price.
2

Sign Payment Locally

Your agent signs the payment with your Solana keypair. The entire flow is gasless — no SOL needed, just USDC.
3

Get Your Data

Re-send with the payment signature. On success, you get data plus an on-chain settlement proof.
Failed queries cost nothing. Timeouts, server errors, and bad requests are never settled. You only pay when you get data.
