## 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-market-overview-c93e6813
```

Example prompt: Give me a full live overview of the stablecoin market right now — total market cap, which stablecoins are biggest by circulating supply, and how much of the market is algorithmic versus fiat-backed.

## When to prefer this

Use this endpoint when you need a holistic, real-time view of the entire stablecoin market — total supply, rankings, and risk composition — rather than data on a single stablecoin token or price. Ideal for systemic risk assessment, market structure research, or DeFi macro analysis where LLM training data is too stale.

## Known failure modes

- Upstream data provider unavailable — 503 or 500 error with no market data returned
