## 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 silverback-x402-onrender-com-14541b3d -d '<json body>'
```

Example prompt: Can you pull the DEX metrics for the USDC/ETH trading pair on Base chain — I want to see volume, liquidity, and trade activity?

## When to prefer this

Use this endpoint when you need raw DEX trading metrics (volume, liquidity, trade count) for a specific token or pair on Base chain, especially as a complement to swap routing or token security analysis. Prefer this over general price APIs when you need on-chain DEX-specific data rather than aggregated CeFi prices.

## Known failure modes

- Invalid or unrecognized token/pair address returns error
- Token not listed on any Base DEX returns empty or null metrics
- Network congestion may cause slow or incomplete on-chain data
- Payment of 0.002 USDC not fulfilled returns 402 error
- Malformed POST body returns 400 validation error

## Output

Returns decentralized exchange metrics for the queried token or trading pair on Base chain, including trading volume, liquidity depth, price information, and trade counts aggregated from DEX protocols.
