## 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-track-records-beat-every-coin-flip-4086beaa
```

Example prompt: Show me which strategies in ManyLives beat every coin-flip baseline over the last 30 days — I want the full ranked list with their return percentages across different time windows.

## When to prefer this

Choose this endpoint when you need to identify strategies that have objectively outperformed random chance (coin-flip baseline) over a rolling 30-day window, especially for cryptocurrency or on-chain strategy screening. It is particularly useful when you want a curated, ranked list with multi-window return data rather than building your own backtesting pipeline.

## Known failure modes

- No strategies meet the coin-flip beat criterion for the period, returning an empty results array
- Simulated data may be marked with an asterisk and carry accuracy caveats
- Ambiguous or unsupported time window inputs may yield unexpected result sets
- API may return stale data if on-chain sources are temporarily unavailable
- Payment failure (x402) if USDC balance is insufficient

## How this service works

No forms, no dropdowns. Describe the outcome in plain words and the Brain asks what it must, lists the job, collects offers and recommends one.

## Output

A JSON object containing a ranked list of strategies that beat every coin-flip strategy in ManyLives' book over a 30-day window. Each result includes a strategy ID, rank, and return percentages across multiple time windows (e.g. 1h, 5y) with source labels indicating whether data is on-chain or simulated. Also returns the criteria description and difficulty level (e.g. advanced).
