## 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 the-stall-crypto-to-fiat-price-lookup-f80798d7
```

## When to prefer this

Use this endpoint when you need a quick, no-account, no-API-key lookup of a cryptocurrency's current price in one or more fiat currencies, paid per-call with micro-USDC. Prefer this over direct CoinGecko API calls when you want a pay-as-you-go model without managing API keys, or when building an agent workflow on the x402 payment rail.

## Known failure modes

- Unknown coin ticker or CoinGecko ID returns a 404 or empty result
- Invalid fiat currency code returns an error or omits that currency from the response
- Network or upstream CoinGecko outage causes a 502 or timeout
- Missing required 'coin' query parameter returns a 400 validation error
- Insufficient USDC balance or failed x402 payment returns a 402 Payment Required response

## How this service works

Cryptocurrency price in any fiat currency — JPY, EUR, CNY, GBP, KRW, INR, AUD, BRL, or 80+ more. Input a coin name or CoinGecko ID (bitcoin, ethereum, solana, btc, eth, sol, etc.) and one or more currency codes. Returns current price, 24h percent change per currency, and last updated timestamp. Free upstream: CoinGecko public API (no key). 85% below specialized fiat oracles. Useful for Asian/European market agents, cross-border DeFi pricing, and multi-currency portfolio valuation.

## Output
