## 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-five-year-survivors-strategy-list-d07b993c
```

Example prompt: Pull up the ManyLives five-year survivors list — I want to see which crypto and stock strategies have stayed profitable over 5 years with a drawdown no worse than -50%, ranked by return.

## When to prefer this

Use this endpoint when you need a pre-screened, ranked list of strategies proven over a full 5-year horizon with enforced drawdown limits, without having to filter raw strategy data yourself. Prefer this over general strategy lists when durability and long-term survival are the primary selection criteria, especially for deploying capital in automated agents.

## Known failure modes

- Payment not processed (HTTP 402) — agent must pay 0.02 USDC via x402 protocol before response is served
- No strategies meeting criteria — empty results array returned if all strategies fail the 5-year drawdown filter
- Stale or computed backtest data — some entries marked 'computed*' may not be fully on-chain verified
- Rate limiting or network errors on Base — payment confirmed but response delayed or dropped
- Malformed response if on-chain data source is temporarily unavailable

## How this service works
