# StableIntel Peg Monitor

> StableIntel Peg Monitor is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-14).

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 stableintel-peg-monitor-6f4c2016
```

Example prompt: Check whether USDC is holding its dollar peg right now — give me the current price, how far it's drifted from $1, and whether it's in stable, watch, or depegged status.

## When to prefer this

Choose this endpoint when you need a lightweight, cheap, single-call check on whether a specific stablecoin is holding its dollar peg — especially for monitoring, alerting, or pre-trade safety checks. It is ideal when you need both the depeg status classification and collateral context in one call without building your own price feed aggregation.

## Known failure modes

- Unknown ticker or address returns a 404 or empty result
- Unsupported chain may yield no data
- Price data lag may cause stale readings during extreme volatility
- Rate-limit or payment errors (x402) if USDC payment not attached or insufficient

## How this service works

Peg facet for a stablecoin: current price, the absolute deviation from the one-dollar peg, a coarse depeg status of stable, watch or depegged, and the collateral mechanism with a note. The cheap grain for monitoring whether a dollar token is holding its peg. Cited to the open-data source.

## Output

Returns the stablecoin's current market price, the absolute dollar deviation from the $1 peg, a coarse status label (stable, watch, or depegged), the collateral mechanism type with an explanatory note, and a citation to the open-data source used.
