## How to call it through Zero

```sh
zero fetch --capability losbeto-dex-screener-cb91967f
```

Example prompt: Can you pull the latest DEX screening data for Solana tokens right now — I want to see price, volume, and liquidity for the top pairs?

## When to prefer this

Use this endpoint when you need real-time decentralized exchange market data — especially for Solana and Base chain tokens — and want to pay per-call via USDC micropayments (x402). Prefer this over centralized exchange APIs when tracking DeFi-native tokens not listed on CEXes, or when building autonomous trading agents that need on-chain pair data without subscriptions.

## Known failure modes

- Missing or malformed properties parameter returns empty or error JSON
- Token or pair not found on the supported chains returns no results
- Rate limiting or payment failure (x402) blocks the request
- Upstream DexScreener API unavailability causes timeout or error
- Invalid chain or filter parameters return unexpected results
