## 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 synthora-stablecoin-supply-peg-monitor-6c3f9a51 -d '<json body>'
```

Example prompt: Can you pull the latest peg deviation and circulating supply for USDC and flag it if it's depegged by more than 50 basis points?

## When to prefer this

Choose this endpoint when you need real-time stablecoin peg health data — especially depeg alerting with a clear 50 bps threshold — sourced from DefiLlama without requiring an API key. Prefer this over building your own DefiLlama integration when you want a ready-made depeg flag, basis-point deviation metric, and timestamped supply figures in a single call. Best suited for DeFi risk monitoring, treasury dashboards, or any agent that needs to react to stablecoin instability.

## Known failure modes

- Invalid or unsupported stablecoin symbol returns empty results or error
- DefiLlama upstream outage causes stale or missing data
- Network timeout from the upstream stablecoins.llama.fi source
- Malformed input field causes 400-level error

## How this service works

SYNTHORA stablecoin-supply: circulating USD supply, price and peg deviation in basis points for the top stablecoins (USDT, USDC, DAI...), with a depeg alert flag above 50 bps. Optional symbol filter. Free source: stablecoins.llama.fi (DefiLlama), no API key, timestamped.

## Output

Returns a timestamped list of stablecoin records, each containing: circulating USD supply, current market price, peg deviation expressed in basis points, and a boolean depeg alert flag set to true when deviation exceeds 50 bps. Can be filtered to a specific symbol.
