## 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-supply-table-with-prices-ee7b7d7c
```

Example prompt: Can you pull up the current stablecoin supply table — I want to see prices and circulating supply for all major stablecoins like USDT, USDC, and DAI?

## When to prefer this

Use this endpoint when you need a broad overview of the stablecoin market — prices and supplies across multiple stablecoins in a single call. Prefer this over single-coin price lookups when comparing stablecoin dominance or monitoring the overall stablecoin ecosystem.

## Known failure modes

- Upstream data provider unavailable — returns 5xx error
- Rate limit exceeded — returns 429
- Payment not processed — returns 402 requiring valid x402 payment
- Empty or stale data if provider cache has not refreshed recently
