## 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 vape-stablecoins-depeg-monitor-2c27526b
```

Example prompt: Pull the latest stablecoin depeg data — I want to see all tracked stablecoins ranked by circulating supply with their live peg price and computed depeg amount so I can spot any that are losing their peg right now.

## When to prefer this

Use this endpoint when you need a live, ranked snapshot of all tracked stablecoins with explicit depeg deviation amounts — particularly useful for systemic risk monitoring, DeFi dashboards, or alerting workflows where catching a de-peg event early matters. Prefer this over generic coin price APIs when the focus is specifically on peg health and circulating supply ranking rather than general price action.

## Known failure modes

- Payment not completed or USDC balance insufficient — 402 Payment Required returned
- Upstream DeFi data provider unavailable — may return 503 or partial data
- No stablecoins currently tracked — returns empty list
- Rate limit exceeded — too many requests in short window

## How this service works

VAPE stablecoins — Stablecoins by circulating supply with live peg price and a computed depeg amount — a de-pegging stablecoin is a live systemic threat signal.

## Output

A ranked list of stablecoins by circulating supply, each entry including the stablecoin's name, current circulating supply, live peg price (e.g. dollar value), and a computed depeg amount indicating how far the coin has drifted from its target peg — a non-zero depeg amount flags a potential systemic threat.
