## 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 402-com-tr-dex-pair-info-82c26741
```

Example prompt: Can you pull up the price, liquidity, 24h volume, and buy/sell counts for the Base DEX pool at address 0x4C36388Be6F416A29C8d8Eee81C771cE6bE14B5?

## When to prefer this

Use this endpoint when you need a quick, structured snapshot of a specific Base DEX pool's market metrics — price, liquidity, volume, and trade counts — especially when you already have the pool address and want DexScreener-sourced data without building a direct DexScreener integration. Prefer this over the sibling routing endpoint when you need pool analytics rather than optimal routing.

## Known failure modes

- Invalid or non-existent pair address returns an error or empty result
- Pair address on a non-Base chain may return no data
- DexScreener data may be delayed or unavailable for very new or illiquid pools
- Missing 'pair' query parameter results in a validation error

## How this service works

Given a Base DEX pair (pool) address, returns price, liquidity, 24h volume, buy/sell transaction counts and FDV from DexScreener. For agents analysing a specific pool's depth and activity.

## Output

Returns a structured object containing the pool's current token price, total liquidity in USD, 24-hour trading volume, number of buy and sell transactions in the last 24 hours, and fully diluted valuation (FDV) — all sourced from DexScreener for the specified Base chain pair.
