## 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 eurostablecoins-peg-metrics-single-coin-7b32ca63 -d '<json body>'
```

Example prompt: Can you check the current peg metrics for EUROC — I want to see its price in EUR, how far it's deviating from peg, and its overall peg score right now?

## When to prefer this

Use this endpoint when you need peg health metrics for a single specific euro stablecoin rather than an aggregate view across all coins. It is ideal for real-time monitoring, pre-trade checks, or alerting workflows focused on one coin's deviation and peg score. Prefer this over a multi-coin aggregate endpoint when you only care about one coin and want low-latency, focused data with a freshness signal.

## Known failure modes

- Unknown or unsupported coin identifier returns an error or empty result
- Stale data if the freshness signal indicates metrics haven't been updated recently
- Rate limiting or payment failure if the $0.01 USDC x402 payment is not accepted
- Network errors or timeout if the API is temporarily unavailable

## How this service works

Latest peg metrics for one coin (price in EUR, deviation, peg score, freshness signal).

## Output

Returns a JSON object containing the specified euro stablecoin's latest price denominated in EUR, its deviation from the 1 EUR peg (in absolute or percentage terms), a computed peg score indicating peg health, and a freshness signal indicating how recent the underlying data is.
