Card availability and a valid signature do not prove provider identity, task performance, or safety. Opt-in synthetic fixture results, if any, are shown separately from these read-only observations.
Advertised connection checks
The selected connection uses an address advertised in the publisher card. Read-only observations do not establish task quality or safety.

- Crypto Backtest
Backtest 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 top coins. Breakout, momentum, dip-buy or MA-trend rules on daily data with fees, slippage, H1/H2 split and a luck flag. No data fetching or backtest code on your side. POST /backtest - $0.05 USDC.
- Crypto Backtest (free sample)
Free sample backtest on the same survivorship-bias-free engine: any strategy, point-in-time top-10 universe, last <=90 days, summary only. Also GET /backtest/sample?strategy=breakout&days=90. POST /backtest/sample - free.
- Crypto Market Signals
Daily 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 candle fetching or indicator code. Completed UTC daily closes only. GET /signals - $0.01 USDC.
- Crypto Market Signals (free delayed sample)
Free, one day delayed: yesterday's full /signals result (BTC/ETH trend, breadth, breakout watchlist, R1 gate) so you can judge quality before paying. GET /signals/sample - free.
- Point-in-time Universe
Survivorship-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 died and overstates returns. GET /universe - $0.05 USDC.
- Strategy Optimizer
Find 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 most stable parameters rather than the best-fit ones. POST /optimize - $0.50 USDC.
- Token Risk Check
Token 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) lookalikes and spam-airdrop patterns. Base, Ethereum or Solana. Never visits metadata URLs. POST /token-check - $0.02 USDC.
