## 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 webbersites-crypto-converter-cad6f8cc
```

Example prompt: How much Ethereum would I get for 0.5 Bitcoin right now? Give me the rate and the converted amount using current CoinGecko prices.

## When to prefer this

Use this endpoint when you need a quick, cheap, real-time crypto-to-crypto or crypto-to-fiat (or fiat-to-crypto) conversion with fresh CoinGecko prices and no complex setup. Ideal for looped or frequent conversion lookups given its low per-call cost and 30s cache. Prefer over manual price math or heavier financial data APIs when you just need a rate and converted amount.

## Known failure modes

- Unrecognized coin ID or ticker returns an error (check CoinGecko IDs for obscure coins)
- Unsupported fiat code returns an error
- Missing required 'from' or 'to' query parameters returns a 400-style error
- Very new or delisted coins may not be found in CoinGecko data
- Network/upstream CoinGecko outage may cause stale or failed responses

## How this service works

Live crypto conversion at CoinGecko prices: any coin to any coin or fiat, and fiat to coin. ?amount=0.5&from=bitcoin&to=ethereum — common tickers (btc, eth, sol…) accepted. Returns the rate, the converted amount, and the underlying prices. Prices cached ≤30s; cheap enough to call in a loop.

## Output

Returns a JSON object with: the 'from' currency identifier, the 'to' currency identifier, the exchange rate (from→to), the input amount, the computed result (amount × rate), and a 'prices' object containing the underlying USD-denominated prices for each currency. Prices are cached for at most 30 seconds.
