13 tools, as the server itself reported during our check on Oct 31, 2026.

• backtestBacktest crypto strategies on 399 Coinbase coins without survivorship bias. DIY backtests usually use today's coin list, so dead coins vanish and returns are overstated; this rebuilds the universe from each past day's to
• market_signalsDaily crypto market regime in one call: BTC/ETH vs 20/50-day MAs, breadth of the point-in-time top-N (no survivorship bias), coins nearest a 20-day breakout, and the R1 breakout strategy's gate and entry signals. No cand
• token_checkToken scam check in one call instead of wiring up five data sources: honeypot sell simulation, unverified code, mint/pause/blacklist powers, taxes, upgradeable proxy, age, liquidity, fake major-token (e.g. fake USDC) loo
• optimize_strategyFind robust strategy params, not lucky ones: tests up to 50 combos on the same survivorship-bias-free backtester, ranks by worst-half (H1/H2) return with neighbourhood smoothing, flags overfitting, and recommends the mos
• universe_snapshotSurvivorship-free top-N coin list for any past date: Coinbase USD pairs ranked by trailing 20-day dollar volume using only data available that day. Fixes your own backtests: picking today's top coins hides the ones that
• signals_sampleFree, one day delayed: yesterday's full /signals result (BTC/ETH trend, breadth, breakout watchlist, R1 gate) so you can judge quality before paying. Today's result: paid market_signals ($0.01). Limit 60/hour per client.
• backtest_sampleFree sample of the paid `backtest` tool on the same survivorship-bias-free engine: any strategy, point-in-time top-10 universe, window = last `days` (14..90) completed days, summary only. Full version: backtest ($0.05).
• healthFree: service status, prices, network and data range.
• get_schemaFree: request schemas, examples, prices and limits for every paid tool/endpoint.
• validate_backtestFree: check backtest arguments (same as the paid `backtest` tool) before paying.
• validate_optimizeFree: check optimize_strategy arguments and count grid combos before paying.
• validate_token_checkFree: format-check a token_check request (no on-chain lookups).
• validate_universeFree: check universe_snapshot arguments (date in range, enough history) before paying.
