## 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 booaip-stablecoins-data-a7d87de1
```

Example prompt: What's the current circulating supply of USDT and how far is it deviating from its peg right now?

## When to prefer this

Use this endpoint when an AI agent needs real-time stablecoin circulating supply and peg health data in a pay-per-call model using USDC on Base via x402. Ideal for crypto-native agent workflows that already support x402 micropayments and need lightweight, on-demand stablecoin metrics without a subscription.

## Known failure modes

- Unrecognized stablecoin symbol returns found: false
- Network or upstream data provider outage returns an error response
- Invalid request body format returns a 400 error
- Payment failure via x402 prevents access to the endpoint

## How this service works

Stablecoin circulating supply, price and peg deviation (DefiLlama). Body: { symbol? }.

## Output
