Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 api2ls-com-erc-20-token-usd-price-30a7385e
```

Example prompt: What's the current USD price of the token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — pull it from on-chain DEX liquidity?

## When to prefer this

Use this endpoint when you need a real-time, on-chain USD price for any ERC-20 token on major EVM networks (Base, Ethereum, Optimism, Arbitrum, Polygon) and want a price derived from actual DEX liquidity rather than a centralized exchange feed. Ideal for DeFi analytics, portfolio valuation, or any agent workflow that must price arbitrary tokens including those not listed on major CEXes.

## Known failure modes

- Token contract address not found on specified chain — returns success:false or error
- Invalid or malformed contract address (non-0x, wrong length) — likely 400 or error response
- Token has no DEX liquidity on the selected chain — price unavailable
- Unsupported chain value — query defaults to base or returns an error
- Network/RPC connectivity issues causing timeout or stale data

## How this service works

Get the live USD price of an ERC-20 token from on-chain DEX liquidity

## Output

A JSON object containing success status, the USD price as a string (e.g. '1.0002'), the token symbol, the queried contract address, the chain, current liquidity in USD, and the timestamp of the price reading.
