## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability riley-craig-x402-agent-store-dex-trading-pairs-lookup-aced71e1
```

Example prompt: What are the current DEX trading pairs for WIF — give me the price in USD, 24-hour volume, liquidity, and price change?

## When to prefer this

Use this endpoint when you need real-time DEX market data (price, volume, liquidity) for a specific token by symbol, name, or contract address without needing a persistent API key. Ideal for agents performing on-chain research or crypto trading analysis that require pay-per-call micropayment access.

## Known failure modes

- Token symbol not found — returns empty pairs array
- Invalid or non-existent contract address — no results returned
- Query parameter 'q' missing — request validation error
- Token exists but has no active DEX pairs — empty result
- Payment failure via x402 — 402 response requiring USDC payment on Base

## How this service works

Live decentralized-exchange trading data for ANY token by symbol, name, or contract address: USD price, 24h volume, liquidity, buy/sell transaction counts, and price momentum across 5m/1h/6h/24h, across every chain and DEX. For crypto trading, sniping, research and portfolio agents that poll the market constantly. One paid call instead of integrating Dexscreener.

## Output

A JSON object containing an array of DEX trading pairs for the queried token, each with pair name (e.g. WIF/SOL), chain, current USD price, 24-hour trading volume, 24-hour price change percentage, and liquidity in USD.
