## 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 santyvv-data-defi-stablecoins-endpoint-1aac4b2e
```

Example prompt: Give me the current market data for all major stablecoins — supply, peg status, and yields — and pay for the lookup with USDC on Base.

## When to prefer this

Choose this endpoint when you need stablecoin data without setting up API keys or accounts, want to pay only for what you use (per-call USDC micropayment), or need a normalized multi-source response that aggregates public on-chain and market data with edge caching for reliability. Ideal for AI agents operating autonomously with a crypto wallet on Base.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted — returns 402 Payment Required
- Rate or network error: upstream public data provider unavailable — may return 503 or partial data
- Invalid query properties: malformed filter parameters — returns 400 Bad Request
- Edge cache miss combined with upstream timeout — slower response or 504

## How this service works

Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.

## Output

A normalized JSON response containing a list of stablecoins with key metrics such as ticker symbol, issuer, circulating supply, market capitalization, current peg price, peg deviation, and available yield data sourced from multiple public on-chain and market data providers.
