## 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-market-overview-api-6c4e8a4e
```

Example prompt: Give me a live overview of the top stablecoins ranked by circulating market cap — I want to see their peg prices, peg mechanisms, and total supply aggregated across all chains.

## When to prefer this

Use this endpoint when you need a quick macro snapshot of the stablecoin landscape — top coins by supply, their peg health, and mechanism type — without querying individual chain APIs. Ideal for DeFi dashboards, risk monitoring, and macro signal pipelines where cross-chain aggregation is required.

## Known failure modes

- Upstream data provider outage returns 502 or empty dataset
- Stale data if aggregation pipeline is delayed
- Payment failure (402) if USDC balance is insufficient
- Rate limiting if called too frequently

## How this service works

Top stablecoins ranked by circulating market cap, with current peg price and peg mechanism, aggregated across all chains. Macro and risk signal for agents. Live stablecoin overview. stablecoin market cap, usdt usdc ranking, peg, stablecoin supply, defi macro Accepts payment on Base or Solana — either network works.

## Output

A ranked list of top stablecoins with each entry including: stablecoin name/ticker, circulating market cap in USD, current peg price, peg mechanism (e.g. fiat-backed, algorithmic, crypto-collateralized), and supply data aggregated across all chains. Useful as a DeFi macro and risk signal snapshot.
