## 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 api-anchor-x402-com-66077b88 -d '<json body>'
```

Example prompt: What's the current USD price of ETH? Also, can you grab the price of the USDC token on Base using its contract address 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.001 USDC) spot USD price for a specific token identified by either its well-known symbol or its on-chain contract address. Prefer this over general financial APIs when working in a crypto-native, agent-driven pipeline that supports x402 micropayments, or when you need contract-level precision across multiple chains including Base, Ethereum, Solana, Polygon, Arbitrum, Optimism, BSC, and Avalanche.

## Known failure modes

- Symbol not recognized — returns error if the token symbol is unknown or unsupported
- Missing required parameter combination — chain provided without contract or vice versa returns validation error
- Unsupported chain slug — unrecognized chain identifier returns an error
- Token contract not found on specified chain — returns error if the contract address does not exist or is not indexed
- Rate or payment failure — x402 payment not accepted results in 402 response

## How this service works

USD token price (POST wrapper, body: {symbol} or {chain, contract}) — $0.001 USDC

## Output

A USD price value for the requested token, returned as a structured JSON object. The caller provides either a token symbol (e.g. BTC, ETH, SOL) or a chain slug plus contract address, and receives the current market price in USD.
