## 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-calmar-strategy-rankings-1y-ac29c63d
```

Example prompt: Pull the top-ranked trading strategies by Calmar ratio over the last year from ManyLives — I want to see which ones have the best annual return relative to their max drawdown, with on-chain verified backtest results.

## When to prefer this

Choose this endpoint when you need to identify trading strategies that maximize return per unit of drawdown risk over a 1-year horizon, particularly when verifiable on-chain provenance is required. Prefer this over generic strategy lists when risk-adjusted performance (Calmar ratio) is the primary selection criterion, and over traditional financial data APIs when you need decentralized, tamper-resistant backtest verification. Ideal for AI trading agents that need to select or rank strategies programmatically without manual account setup.

## Known failure modes

- Payment not received or USDC balance insufficient — 402 Payment Required returned
- Invalid or missing x402 payment header — authentication failure
- No strategies meet the Calmar ratio threshold for the requested period — empty results list
- API rate limiting or server overload — 429 or 503 response
- On-chain data source temporarily unavailable — partial results with computed fallback marked with asterisk

## Output

Returns a ranked list of trading strategies sorted by highest Calmar ratio (annual return divided by max drawdown) over the last year.
