How this service works
Pay-per-call adjudication for trading research. Eleven gates that killed 35 of our own concepts. Is your backtest real, is your price data real, is your t-stat inflated? USDC on Base, no account needed.
Output
Returns a JSON object with a 'reading' field describing the deflation-adjusted Sharpe ratio analysis and a 'verdict' field indicating whether the strategy's performance is statistically credible after correcting for the number of searches or trials conducted.
Example use cases
Quant researcher validating best strategy
“I backtested 200 different strategies and the best one shows a Sharpe ratio of 1.8 — can you deflate that Sharpe for the 200 trials I ran and tell me if it's genuinely significant or just selection luck?”
DeFi yield strategy sanity check
“My DeFi yield strategy posted a Sharpe of 3.2 but I tried about 30 variations before landing on it — run the deflated Sharpe calculation and tell me if this result is real or just the luckiest of 30 attempts.”
Pre-submission backtest credibility check
“Before I pitch this strategy to investors, I want to know if the Sharpe of 2.5 holds up — I explored roughly 15 configurations to get here, so please deflate it for selection bias and give me a verdict.”

Endpoint
POSThttps://money-mind-extract.onrender.com/deflatedsharpe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a rigorous, pay-per-call statistical correction for Sharpe ratios inflated by running multiple backtests or parameter searches — especially when you need a fast, no-account verdict before pitching a strategy or publishing results. Prefer this over manual Probabilistic Sharpe Ratio (PSR) calculations when you want an authoritative adjudication without building the math yourself.
