## 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 signal-nodus-token-price-12cbb2ba
```

Example prompt: What is the current USD price and 24-hour trading volume for USDC right now?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call real-time token price lookup with no subscription required, particularly in agentic workflows where USDC micropayment via x402 is already set up.

## Known failure modes

- Unknown or unsupported token symbol returns an error or empty response
- Network timeout if the upstream price feed is unavailable
- Payment failure (402) if USDC micropayment is not completed before the call
- Rate limiting if too many requests are made in a short window
