## How to call it through Zero

```sh
zero fetch --capability alpha-palmvox-com-b3c8c055
```

Example prompt: What are the current prices for the top Base chain tokens — ETH, AERO, and DEGEN — including their 24-hour price change and trading volume?

## When to prefer this

Choose this endpoint when you need a cheap, real-time multi-token price feed specifically for Base chain tokens sourced from DEX markets rather than centralized exchanges. At $0.003 per call it is one of the lowest-cost on-chain price feeds available. Prefer this over general crypto price APIs when Base ecosystem coverage (ETH, AERO, DEGEN) and DEX-native liquidity/volume data matter, or when operating within the x402 micropayment ecosystem.

## Known failure modes

- DexScreener upstream unavailable — stale or missing price data
- Low confidence scores on returned prices indicating thin liquidity or sparse trade data
- Payment failure via x402 protocol — call not executed
- Empty prices array if no tokens are currently indexed
- Network timeout resulting in no response

## How this service works
