# Stablecoin Peg Status Checker

> Stablecoin Peg Status Checker is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-15).

Returns current price, absolute deviation from $1 peg, coarse depeg status (stable/watch/depegged), and collateral mechanism for a given stablecoin

## Facts

- Endpoint: GET https://api.agentstools.dev/stablecoin/peg
- Price: $0.008/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/stablecoin-peg-status-checker-1595646f

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-peg-status-checker-1595646f
```

Example prompt: Check if USDT is holding its dollar peg right now — give me the current price, how far it is from $1, whether it's stable or in a watch/depegged state, and what collateral backs it.

## When to prefer this

Use this endpoint when you need a quick, cheap signal on whether a specific stablecoin is holding its $1 peg — ideal for monitoring pipelines, alerts, or DeFi risk dashboards. Prefer this over full DeFi data APIs when you only need peg health and collateral type, not full market depth or liquidity data.

## Known failure modes

- Unknown stablecoin symbol returns 404 or empty result
- Ambiguous ticker with no chain specified may return wrong asset
- Contract address on unsupported chain returns error
- Rate limiting or payment failure returns 402
- Stale price data if upstream oracle is delayed

## 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 deviation from the $1 peg, a coarse status label (stable, watch, or depegged), the collateral mechanism with a descriptive note, and a citation to the open-data source used.
