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. No API keys, no accounts, no onboarding. Three payment protocols supported — pick the one that fits your stack.

​
See It in Action

Watch the Data Agent answer real queries across all three platforms.

​
What You’ll Access

Polymarket

38 endpoints. Trending markets, smart money consensus, insider detection, wallet profiling, alpha caller tracking, and capital flow analysis.

Hyperliquid

18 endpoints. Trader leaderboards, daily PnL, fresh whale detection, long/short pressure, and smart wallet signals.

Meteora

18 endpoints. Pool trending, LP rankings, volume heatmaps, fee analysis, DCA accumulation pressure, and position tracking.

​
How Payment Works

Every paid request follows the same settle-after-execute pattern, regardless of which protocol you use.
1

Request Data

Call any endpoint. The server responds with HTTP 402 and the exact USDC price, along with payment instructions for all supported protocols.
2

Sign Payment Locally

Your agent signs a USDC transfer transaction with your wallet. The transaction is not broadcast — it stays local as proof of payment intent.
3

Re-send With Payment

Attach the signed transaction and re-send the same request. The server validates the transaction, runs your query, and only then broadcasts the payment on-chain.
4

Get Your Data

On success, you receive your data plus an on-chain settlement receipt. If the query fails, times out, or returns empty results, the transaction is discarded and you are never charged.
Failed queries cost nothing. Timeouts, server errors, and empty results are never settled. You only pay when you get data.

​
Three Payment Protocols

All three deliver the same data at the same price. The 402 response includes payment challenges for every available protocol — your client picks whichever it supports.

​
Pricing

Multipliers apply for longer timeframes and higher result limits.

​
What This API Covers (and What It Doesn’t)

This is read-only analytics. You get smart money intelligence, wallet scoring, and market signals across three platforms. No trade execution.
