## 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 synapse-xrp-price-ad1bc4e9
```

Example prompt: What's the current price of XRP in USD? Pay the micro-fee automatically.

## When to prefer this

Choose this endpoint when you need a quick, no-account, no-API-key XRP price lookup and are already operating in an x402 micropayment context on Base. It is ideal for AI agents that handle their own USDC payments autonomously and need lightweight per-call pricing data without subscription overhead.

## Known failure modes

- Payment failure if USDC balance on Base is insufficient or x402 header is missing
- Stale or unavailable price data if upstream data source is unreachable
- HTTP 402 returned if payment is not properly attached
- Network timeout if the duckdns host is temporarily offline
