## How to call it through Zero

```sh
zero fetch --capability api-deepbluebase-xyz-5152a81d
```

Example prompt: What's the current USD price of ETH right now, pulled live from the Base DEX pools?

## When to prefer this

Use this endpoint when you need a real-time, low-latency USD price for a token available on Base DEX pools, especially ETH. Prefer this over aggregator APIs when you specifically need Base chain DEX pricing context rather than centralized exchange prices.

## Known failure modes

- Invalid or unsupported token symbol in the path returns an error or empty response
- Network or DEX pool data unavailability causes a fetch failure
- Payment not processed (x402 payment required) results in 402 response
- Stale or delayed price data if upstream DEX pool feed lags
