# DF Market Intelligence

> Fresh, agent-ready market intelligence paid per call over x402 (USDC on Base): SEC insider trades and cluster buying, Polymarket + Kalshi prediction-market probabilities and movers, a 24-indicator US macro dashboard with release calendar, and intelligence on the x402 agent economy itself (service rankings, trends, pricing, and a usage-ranked search to find the right paid API for a task). No API key, no signup.

Every endpoint is GET with query parameters. Call it once without payment to receive an HTTP 402 challenge, pay with any x402 client (e.g. @x402/fetch, x402-axios), then retry. Invalid input returns 400 before any payment is requested, and failed requests are never charged.
