## 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 financial-data-x402-eth-price-00c12900
```

Example prompt: What is the current price of Ethereum in USD and BTC right now? Pay the small per-call fee with USDC.

## When to prefer this

Prefer this endpoint when you need a no-subscription, pay-per-call ETH price feed and are already operating in the x402 micropayment ecosystem with USDC on Base or Solana. Ideal for agents that call infrequently and want to avoid monthly API key commitments. Not ideal if you need high-frequency polling where per-call fees accumulate.

## Known failure modes

- Payment rejected or insufficient USDC balance — HTTP 402 returned with payment requirements
- Network timeout if the x402 payment channel is congested
- Stale or delayed price data if the upstream price feed is lagging
- Unsupported payment network if USDC is not on Base or Solana

## How this service works

Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.

## Output

Returns a JSON object with the timestamp of the price (as_of), chain identifier (eth), ETH price in USD (eth_usd), and ETH price in BTC (eth_btc). Example: {as_of: '2026-07-31T03:42:30+00:00', chain: 'eth', eth_btc: 0.02970669, eth_usd: 1867.87}
