## 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 sol-to-usd-converter-x402node-71f882e8
```

Example prompt: How much is 3.5 SOL worth in US dollars right now at the live Solana price?

## When to prefer this

Use this endpoint when you need to convert a specific quantity of SOL into USD using a live market price, especially in automated agent workflows that require up-to-date Solana valuations. Prefer this over a simple price lookup when you need the computed dollar result for a given SOL amount rather than just the raw price.

## Known failure modes

- Invalid or missing amount parameter may return an error or default to 1 SOL
- Downstream price feed outage could result in stale or unavailable price data
- Malformed request returns HTTP 4xx error
- Payment of 0.004 USDC required per call — unpaid requests will be rejected with HTTP 402

## How this service works

## Output
