## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability manylives-high-win-ratio-strategies-1y-86b6183f
```

Example prompt: Can you pull the ManyLives list of strategies with the highest win ratios over the past year — I want to see which crypto or stock strategies have won the most consistently, ranked by win rate?

## When to prefer this

Use this endpoint when you need a pre-filtered, ranked list specifically optimized for win rate consistency over 1 year — as opposed to maximum return or Sharpe ratio. Prefer this over general market data APIs when you want verifiable, on-chain-locked backtests rather than self-reported performance. Best for agents that need to select strategies based on reliability and consistency rather than peak return. At $0.02 per call with no account required, it is ideal for pay-per-use agent workflows.

## Known failure modes

- Payment not processed (402): USDC payment of $0.02 not attached or invalid — endpoint requires x402 micropayment
- No strategies match criteria: empty results list returned if no strategies qualify
- Rate limiting or network errors on Base network payment verification
- Stale or unavailable backtest data: some time windows may return computed estimates rather than on-chain verified data (marked with asterisk)
- Malformed request: missing or invalid query parameters return an error

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

A JSON object containing a ranked list of strategies sorted by highest win ratio over 1 year. Each entry includes a strategy ID (e.g. CRY-1h-042), rank, performance data across multiple time windows (e.g. 1h, 5y) with return percentages and data source labels (on-chain or computed), and metadata about the ranking criteria used (highest share of winning periods over a year, profitable overall). The result is labeled as 'advanced' level.
