## 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 x402-toolbox-stablecoin-market-overview-37d51092
```

Example prompt: Give me a market overview of the major stablecoins right now — I want to see prices, market caps, and key stats for USDC, USDT, DAI, and the others.

## When to prefer this

Choose this endpoint when you need a broad, multi-stablecoin market overview in a single call without API key registration, especially in agentic pipelines that support x402 micropayments on Base. Prefer it over exchange-specific or single-coin endpoints when you want a holistic snapshot of the stablecoin sector.

## Known failure modes

- Payment not received or x402 payment handshake fails — endpoint returns 402 Payment Required
- Invalid or malformed schema parameter — may return an error or fallback response
- Upstream data source unavailable — may return stale or empty data
- Rate or quota issues on the worker — potential 503 or timeout

## How this service works
