## 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-token-pairs-lookup-9eaeb86c
```

Example prompt: Look up DEX trading data for WIF — give me the current price in USD, 24-hour volume, liquidity, and price change across all pairs.

## When to prefer this

Use this endpoint when you need real-time DEX trading pair data (price, volume, liquidity) for a specific token identified by symbol, name, or contract address, and you want to pay per call in USDC with no API key or signup. Prefer this over centralized exchange APIs when you need on-chain DEX-specific data like liquidity and pair information.

## Known failure modes

- Token not found on any DEX — empty pairs array returned
- Invalid or unrecognized contract address — may return no results
- Payment failure via x402 — 402 response if USDC balance insufficient
- Network timeout if DEX data source is slow
- Token exists but has no liquidity — pairs returned with zero values

## 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 with an array of trading pairs, each containing the pair name (e.g. WIF/SOL), the chain (e.g. solana), current price in USD, 24-hour volume in USD, 24-hour price change percentage, and liquidity in USD, along with the original query string.
