## 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 eth-price-quote-29b546eb
```

Example prompt: What's the current price of ETH in USD and BTC right now?

## When to prefer this

Choose this endpoint when you need a fast, lightweight ETH price snapshot in USD and BTC with minimal overhead. It is ideal for quick checks, triggering price alerts, or enriching transaction data with current ETH value. If you need market cap, volume, or supply data, use /crypto-prices instead. At $0.005/call, it is cost-effective for high-frequency price polling.

## Known failure modes

- Unsupported chain parameter (only 'eth' is supported) returns an error
- Etherscan upstream API unavailability may cause request failure or stale data
- Payment failure (insufficient USDC balance or x402 protocol error) results in 402 response
- Network timeout if Etherscan V2 is slow to respond

## How this service works

Current ETH price in USD and BTC, from Etherscan's V2 API. A quick single-value price check -- for market cap/volume/supply detail use /crypto-prices instead. Not address-specific. $0.005/call.

## Output

Returns the current ETH price as a single snapshot: ETH/USD and ETH/BTC values sourced from Etherscan's V2 API. Does not include market cap, volume, or circulating supply — for those use the /crypto-prices endpoint instead.
