## 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 x402-silverbackdefi-app-592dd361 -d '<json body>'

Example prompt: Can you pull the DEX metrics for USDC on Base chain — I want to see trading volume, liquidity, and transaction counts from the last 24 hours across major decentralized exchanges.

## When to prefer this

Use this endpoint when you need aggregated DEX trading statistics and performance metrics for DeFi tokens, especially on Base chain. Prefer this over general price APIs when you need volume, liquidity, and on-chain activity data specific to decentralized exchanges rather than just spot price.

## Known failure modes

- Invalid or unsupported token address returns 400 error
- Unsupported chain or DEX protocol returns 404 or empty result
- No trading activity in specified time range returns empty metrics
- Payment not fulfilled results in 402 Payment Required
- Rate limiting or overload returns 429 or 503

## Output

Returns aggregated DEX performance metrics including trading volume, liquidity depth, price data, transaction counts, and other on-chain trading statistics for the queried token or trading pair across decentralized exchanges.
