# Vextorium Stablecoin Depeg Monitor

> Vextorium Stablecoin Depeg Monitor is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-11).

Returns a list of USD-pegged stablecoins that have deviated from their $1 peg beyond a configurable threshold, using price data aggregated by DefiLlama.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 vextorium-stablecoin-depeg-monitor-6e172f4d -d '<json body>'
```

Example prompt: Check which USD-pegged stablecoins are currently depegged by more than 1%, only including ones with a market cap above $5 million.

## When to prefer this

Use this endpoint when you need real-time detection of stablecoin depeg events across a broad set of USD-pegged stablecoins, with configurable sensitivity via threshold and market cap filters. Prefer this over manual price checks or exchange APIs when you want a single aggregated view across many stablecoins sourced from DefiLlama data.

## Known failure modes

- Invalid threshold_pct value (non-numeric or out of reasonable range) may return an error or unexpected results
- If DefiLlama price feed is unavailable, data may be stale or endpoint may error
- Specifying a very high min_cap may return zero results with no error signal
- Network timeouts for the upstream price aggregation source

## How this service works

USD stablecoins currently trading away from their peg beyond a threshold, with price, deviation, market cap and mechanism. Early risk alert for treasuries and protocols. DefiLlama prices.

## Output

Returns a JSON object with the number of stablecoins reviewed, the count that are depegged, the threshold used, and an array of depegged stablecoin objects each containing name, symbol, mechanism (e.g. algorithmic, crypto-backed), current price in USD, deviation percentage from $1, and market cap in USD.
