## 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 agent-souk-base-token-market-snapshot-9a5037bc -d '<json body>'
```

Example prompt: What's the current live price, deepest liquidity pool, and 24-hour trading volume for USDC on Base? Also check the balance for my wallet 0xAbCd1234AbCd1234AbCd1234AbCd1234AbCd1234.

## When to prefer this

Choose this endpoint when you need a real-time, on-chain market snapshot for a specific ERC-20 token on the Base network — including live price, liquidity pool depth, 24-hour volume, and optionally a wallet's token balance. It is deterministic (no LLM), making results consistent and auditable. Prefer it over general-purpose DeFi APIs when you specifically need Base network data with pool-level granularity and integrated wallet balance checks in a single call.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty result
- Token not listed on any Base pool returns no pool or volume data
- Unknown token alias returns a validation error
- Invalid wallet address format (not matching 0x + 40 hex) rejected by schema
- Token with no trading activity returns zero or null volume
- Payment not received or insufficient USDC causes 402 rejection
