# Stablecoin De-Peg Monitor

> Stablecoin De-Peg Monitor is a paid API for AI agents from stablecoins.x402utils.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-11).

Returns real-time supply, price, and peg deviation data for tracked stablecoins, plus a filtered list of stablecoins currently off their peg.

## Facts

- Endpoint: GET https://stablecoins.x402utils.workers.dev/v1/depegs?utm_source=zero.xyz

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 stablecoin-de-peg-monitor-8a6677f6
```

Example prompt: Show me all stablecoins that are currently depegged by more than 0.5%, and only include ones with a circulating supply above $50 million.

## When to prefer this

Choose this endpoint when you need a focused, ready-to-use depeg alert feed for stablecoins without building your own price aggregation — especially useful for DeFi risk monitoring agents, trading bots, or dashboards that need a pay-per-call model with no subscription overhead. It is purpose-built for stablecoin peg health rather than general crypto price data.

## Known failure modes

- Invalid threshold or min_supply parameter format returns an error
- If no stablecoins breach the threshold, the depegged array is empty (not an error)
- Payment failure via x402 prevents access to the endpoint
- Upstream price feed outage may return stale or missing data

## How this service works

Stablecoin monitor for agents: supply, price and peg deviation for every tracked stablecoin, plus a de-peg alert list. Paid per call via x402 (USDC on Base).

## Output

A JSON object containing a 'depegged' array of stablecoins that breach the requested deviation threshold, each with their symbol, current price, and deviation percentage, plus the threshold value used for the query.
