## 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 dex-pair-info-lookup-726825e4
```

Example prompt: Can you pull up the DEX pair info for the ETH/USDC trading pair — I want to see the current price, liquidity reserves, and which exchange it's on?

## When to prefer this

Use this endpoint when you need real-time on-chain DEX pair data — price, reserves, and liquidity — without signing up for an account or managing an API key. It is ideal for AI agents operating autonomously in DeFi workflows where payment-as-identity (x402/USDC) is the access model. Prefer this over centralized exchange APIs when you specifically need decentralized, on-chain pair data.

## Known failure modes

- Invalid or unrecognized pair address returns an error or empty result
- Token symbol ambiguity may return wrong pair if multiple pools exist
- Pair not found on supported DEX returns a not-found error
- Network congestion or RPC issues may cause delayed or failed responses
- Malformed schema parameter returns a validation error

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object containing on-chain DEX pair information such as token names, token symbols, current price, reserve amounts, liquidity depth, trading volume, and the name of the decentralized exchange hosting the pair.
