## What it does

Free, read-only MCP endpoint. Start with signal\_latest\_preview \(shape of today's brief\), then list\_catalog. The full dated brief is sold separately at the origin over x402: POST https\://draconic21-x402-api.onrender.com/v1/signal\_latest for 0.03 USDC on Base or Solana, with expect\_sha256 so you pay only for the revision you checked. Free checks before paying: /health \(date, sha256, archive depth\), /signal/scorecard.json \(past calls, misses kept\) and /llms.txt. Coverage varies by edition; sampled transfers and directory activity are not verified buyer revenue.
