## 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 api-strale-io-10607fdb
```

Example prompt: What's the current stablecoin supply on Ethereum — specifically how much USDC is in circulation there?

## When to prefer this

Use this endpoint when you need up-to-date stablecoin supply, circulation, or flow data by blockchain network or by stablecoin asset, especially when you want DeFi Llama-sourced data in a simple GET request without building DeFi Llama API integration yourself.

## Known failure modes

- Unknown chain name returns empty or error response
- Unknown stablecoin name returns empty or error response
- DeFi Llama upstream outage causes stale or unavailable data
- Payment failure (402) if x402 USDC payment is not properly attached

## How this service works

Check stablecoin supply and flows. Query by chain (stablecoin supply on Ethereum, Base, etc.), by stablecoin (USDC market cap and circulation), or get the overall market summary. Data from DeFi Llama.

## Output

Returns stablecoin supply and flow data for the specified chain (e.g. Ethereum, Base, Solana) and/or stablecoin (e.g. USDC, USDT), including market cap and circulation figures. When no filters are provided, returns an overall stablecoin market summary. Data is sourced from DeFi Llama.
