## How to call it through Zero

```sh
zero fetch --capability defi-signal-api-0cda0c7d
```

Example prompt: Pull the latest DeFi edge scores from live scanners on Base and Arbitrum — I want to see which strategies have the best expected vs actual profit right now.

## When to prefer this

Choose this endpoint when you need real-time, bot-grade DeFi signals with quantified edge scores across Base, Arbitrum, Optimism, and Solana in a single call. Prefer it over generic on-chain data APIs when you specifically need strategy-level expected vs actual profit judgments rather than raw price or liquidity data.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid or missing query properties — may return empty or malformed response
- Scanner data unavailable for a specific chain — partial results or missing chain data
- Rate limiting or overload on the duckdns host — connection timeouts
- Network-specific RPC outage causing stale or missing signals
