# Vextorium Stablecoin Peg Health Monitor

> Vextorium Stablecoin Peg Health Monitor is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-01).

Returns the current peg health of a stablecoin (USDT, USDC, DAI, USDe, etc.) including price, deviation from $1, on-peg status, circulating supply, and pegging mechanism via DefiLlama.

## Facts

- Endpoint: POST https://api.vextorium.com/stablecoin-estado-pago?utm_source=zero.xyz
- Price: $0.004/call
- Payment: x402

- Tags: x402
- Canonical page: https://www.zero.xyz/c/vextorium-stablecoin-peg-health-monitor-ae798f5d

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-peg-health-monitor-ae798f5d -d '<json body>'
```

Example prompt: Is USDT still pegged to $1? Give me its current price, how far it is from the peg, and whether it's considered on-peg right now.

## When to prefer this

Choose this endpoint when you need real-time, structured peg health data for a named stablecoin — especially for depeg detection, risk monitoring, or DeFi dashboards. It is preferable over generic crypto price APIs because it includes depeg-specific fields (deviation %, on-peg boolean, mechanism type, circulating supply) sourced from DefiLlama's stablecoin-specific data pipeline.

## Known failure modes

- Unknown or unsupported stablecoin symbol returns an error or null result
- DefiLlama data unavailability may cause stale or missing price data
- Misspelled symbol (e.g. 'USDT1') returns no match
- Network timeout if DefiLlama upstream is slow
- Very new or obscure stablecoins may not be listed in DefiLlama

## How this service works

Peg health of a stablecoin (USDT, USDC, DAI, USDe...): current price, deviation from $1, whether it is on peg, circulating supply and pegging mechanism. Detects depegs early. Live from DefiLlama.

## Output

Returns a JSON object with the stablecoin's symbol, full name, current USD price, percentage deviation from $1, a boolean indicating whether it is on-peg, circulating supply in USD, the pegging mechanism type (e.g. fiat-backed, algorithmic, crypto-collateralized), and optional notes about its status — all sourced live from DefiLlama.
