# hyperD - pre-trade DeFi intelligence for AI agents Pay-per-call x402 APIs an agent can **discover, pay for, and call in a single HTTP round-trip** - USDC on Base, ~2s settlement, **no accounts, no API keys, no subscription**. A wallet with a few dollars of USDC is all it takes. **24 paid tools across 7 EVM chains, $0.005–$1.50 per call.** **Data & risk ($0.005–$0.10):** multi-chain balances · DeFi yield · token metadata + GoPlus security · wallet risk + Chainalysis sanctions · protocol TVL · gas oracle · DEX route aggregation · wallet persona · contract audit · DAO proposal summaries · Farcaster sentiment · cross-protocol liquidation risk · wallet anomaly detection · realized/unrealized P&L (FIFO/LIFO/HCFO) · budget guardian · mixer-exposure screening. **Premium synthesis tier ($0.30–$1.50)** — composed one-call verdicts authored by Claude Haiku 4.5, each fanning out multiple sub-calls into a single answer: - `risk.full_audit` ($0.35) — composed wallet risk verdict (balance + sanctions + persona + contract + mixer) - `token.archetype` ($0.30) — stablecoin / blue-chip / mid-cap / memecoin / wrapped / governance - `wallet.thesis` ($0.50) — plain-language behavioral thesis (trader / hodler / yield-farmer / …) - `wallet.threat_brief` ($1.50) — 2–3 sentence security verdict (clean / watch / elevated / critical) - `gov.translate` ($1.00) — Snapshot/Tally proposals in plain language - `yield.allocation` ($1.00) — portfolio split across risk tiers Plus `bundle` ($0.20) — up to 10 paid GETs in one x402 settlement. **Try it free:** first 5 calls/IP/day (10 lifetime), no wallet required. The premium synthesis tier always requires payment. **How it works:** each tool call hits `api.hyperd.ai`, receives an HTTP 402, signs an EIP-3009 USDC authorization with your wallet, retries with the payment header, and returns data ~2 seconds, settled on Base via Coinbase's CDP facilitator.
