## How to call it through Zero

```sh
zero fetch --capability defi-signal-api-e27203b9
```

Example prompt: Pull the latest DeFi bot signals from the live scanners — I want to see recent near-win arbitrage events across Base, Arbitrum, Optimism, and Solana from the last couple of hours.

## When to prefer this

Choose this endpoint when you need raw, real-time DeFi bot signals and near-win arbitrage event data sourced directly from live on-chain scanners across Base, Arbitrum, Optimism, and Solana — particularly if you want niche bot-oriented signal data rather than aggregated price feeds or standard DEX swap data.

## Known failure modes

- No signals available if scanners have no recent activity — empty result set
- Payment failure if USDC balance is insufficient for the $0.002 per-call fee
- Network-specific data unavailable if a chain scanner is offline or lagging
- Malformed or undocumented query parameters may return unexpected results given the loose input schema
- DuckDNS dynamic hostname may be unreachable if the host's IP changes or goes offline
