# Vextorium USD Stablecoin Depeg Alert

> Vextorium USD Stablecoin Depeg Alert is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-20).

Returns a list of USD-pegged stablecoins currently trading beyond a configurable deviation threshold from $1, with price, deviation %, market cap, and mechanism data sourced from DefiLlama.

## 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-usd-stablecoin-depeg-alert-ed87ca3a -d '<json body>'
```

Example prompt: Show me all USD stablecoins currently trading more than 1% away from their $1 peg — include their price, deviation, market cap, and whether they're algorithmic or crypto-backed.

## When to prefer this

Choose this endpoint when you need a market-wide sweep of all USD stablecoins currently off their peg in a single call, rather than checking a single stablecoin's peg health. Ideal for treasury risk monitoring, DeFi protocol risk management, or building depeg alert systems. It complements the sibling single-stablecoin peg health endpoint when you need broad market coverage rather than deep detail on one asset.

## Known failure modes

- Empty stablecoin list if no coins exceed the configured threshold (valid response, not an error)
- DefiLlama price feed unavailability causing stale or missing price data
- Invalid threshold value types causing request rejection
- Very high minimum market cap filter excluding all stablecoins from results

## 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

A JSON object containing: total number of USD stablecoins reviewed, the configured deviation threshold, count of depegged stablecoins found, and an array of depegged stablecoins each with name, symbol, mechanism (algorithmic/crypto-backed/etc.), current USD price, deviation percentage from $1, and market capitalization in USD. Also includes a note about data sourcing from DefiLlama.
