− > Pay-per-call crypto quant tools for agents, paid in USDC over x402: strategy backtests and parameter optimisation on Coinbase daily candles with a survivorship-bias-free point-in-time universe, daily market signals, point-in-time top-N universes, and token contract risk checks (Base, Ethereum, Solana).− - [POST /backtest](https://grok-backtest-api.fly.dev/backtest) - $0.05 USDC - Backtest any crypto strategy on 399 Coinbase coins, bias-free. Breakout, momentum, dip-buy or MA trend rules on Coinbase daily data with fees, slippage, H1/H2 split, luck flag and survivorship-bias-free universe. Free pre-check: POST /validate.− - [GET /signals](https://grok-backtest-api.fly.dev/signals) - $0.01 USDC - Daily crypto market regime: BTC/ETH trend, breadth, breakout watchlist. BTC/ETH vs 20/50-day MAs, market breadth (% of point-in-time top-N above 20DMA), coins nearest a 20-day breakout, and the R1 breakout strategy's gate and entry signals. Completed UTC daily closes only.− - [POST /token-check](https://grok-backtest-api.fly.dev/token-check) - $0.02 USDC - Token scam check: honeypot, mint/pause/blacklist, fake-USDC lookalikes. Scam/honeypot/rug risk check for a Base, Ethereum or Solana token: unverified code, sell restrictions, mint/pause/blacklist powers, taxes, upgradeable proxy, age, liquidity, fake major-token impersonation and spam-airdrop patterns. Never visits metadata URLs. Free pre-check: POST /validate/token-check.− - [POST /optimize](https://grok-backtest-api.fly.dev/optimize) - $0.50 USDC - Find robust strategy params, not lucky ones: tests up to 50 combos of a backtest strategy; ranks by worst-half (H1/H2) return with neighbourhood smoothing, flags overfitting, and recommends the most robust parameters rather than the best-fit ones. Free pre-check: POST /validate/optimize.− - [GET /universe](https://grok-backtest-api.fly.dev/universe) - $0.05 USDC - Survivorship-free top-N coin list for any past date. Top-N Coinbase USD pairs by trailing 20-day dollar volume as of a past date, using only data available that day (survivorship-bias-free universe for backtests).
