### Description (declared)

Pay-per-call crypto quant tools for AI agents, paid in USDC over x402 (no sign-up, no API key). Skip writing your own backtester. Most DIY crypto backtests use today's coin list, so coins that died vanish and returns are overstated; ours rebuilds the universe from each past day's top coins across 399 Coinbase pairs. Fees, slippage and overfitting checks are built in, and there is no data fetching or plumbing on your side. Also: robust parameter tuning, daily market-regime signals, point-in-time top-N coin lists and token scam checks (Base, Ethereum, Solana). Free samples: GET /signals/sample and POST /backtest/sample.
