api-production-54bd
Agent-ready trading & market-data API. 23 endpoints across crypto/stock prices & OHLCV, indicators (ATR, Fair Value Gaps, ICT liquidity levels), perp funding/OI, order books, Kalshi prediction markets, DeFi TVL, volatility, a verified macro calendar, and an AI momentum score. **Access — two ways, both work on every /v1 endpoint:** 1. **API key** — send an `x-api-key` header for free, rate-limited access. 2. **x402 pay-per-call** — no signup: call any endpoint with no key, receive a `402` with a USDC price (currently $0.001/request on base), pay via an x402 client, and get `200` + data.

On-chain payments
Payment shape (4 most recent sampled): 4 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-10-01: 1 payments. Last indexed day 2026-10-04: 1. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. Methodology.
