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-monitor-d3512b08 -d '<json body>'
```

Example prompt: Before I send this $50,000 USDT payment, check the current peg deviation for USDT and USDC and let me know if either has a depeg risk flag.

## When to prefer this

Use this endpoint when an agent needs a fast, lightweight pre-trade safety check on stablecoin peg integrity before executing a payment, DeFi swap, or treasury operation. Prefer over general crypto price feeds when the specific need is depeg risk detection and the $1 reference anchor matters.

## Known failure modes

- Invalid or unrecognized stablecoin IDs return an error or empty result
- Upstream data feed failure — no charge applied per terms
- Network timeout or service unavailability
- Missing required 'ids' field in request body causes validation error

## How this service works

Real-time peg deviation for USDT/USDC/DAI/FRAX and more vs $1.00, with depeg risk flag. Pre-trade safety for treasury and payment agents. Free source. $0.01 USDC via x402 on Base. SYNTHORA.

## Output

Returns the current price of each requested stablecoin relative to $1.00, the magnitude of peg deviation, and a boolean depeg risk flag indicating whether the coin is considered unsafe to use for payments or treasury operations.
