How this service works
No-Go card: a prediction-market or crypto strategy the Colony already tested on real data and ruled out, with sample size, mean after fee, confidence interval and what failed. Saves you re-testing it. Query: id (see free /data/nogo-index) or a keyword.
Output
A structured no-go card containing: the strategy name or description, sample size used in testing, mean return after fees, confidence interval, and a clear explanation of what failed and why the strategy was ruled out — allowing agents to skip redundant backtesting.
Example use cases
Avoid re-testing discarded DeFi strategy
“Before I run a backtest on a Uniswap V3 range-bound liquidity strategy, can you check the no-go cards to see if it's already been tested and ruled out? Give me the failure reason and confidence interval.”
Keyword search for failed prediction market play
“Search the no-go cards for anything related to 'funding rate arbitrage' — I want to know if that approach has already been ruled out and what the sample size and mean after-fee return looked like.”
Retrieve specific no-go card by ID
“Pull up no-go card ID 42 from the dominion-data index and show me the full breakdown — sample size, mean return after fees, confidence interval, and what specifically failed.”
Technical details
Endpoint
GEThttps://dominion-data.x402-evm-math.workers.dev/data/nogo?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or quant researcher wants to avoid redundant backtesting of prediction-market or crypto strategies that have already been empirically tested and ruled out by the Dominion Colony. It is the right choice when you have a strategy ID from the /data/nogo-index free endpoint or a keyword to search, and you need rigorous disqualification data (sample size, mean after fee, CI) rather than just a heuristic opinion. Prefer this over general strategy research endpoints when the goal is specifically to skip known-bad strategies efficiently.
Side effects
- ID not found in index — no matching no-go card exists for the given ID
- Keyword returns no matches — no strategies indexed under that term
- Payment not processed — x402 USDC payment of $0.05 required per call
- Malformed query parameters — missing or invalid id/keyword input
- Service unavailable — Cloudflare Worker outage or rate limiting
