Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 chainray-stablecoin-monitor-0b1d6592
```

Example prompt: Pull the current stablecoin monitor data for Base — I want to see peg stability, supply, and any anomalies across the major stablecoins on that chain.

## When to prefer this

Use this endpoint when you need real-time stablecoin health and supply data for a specific blockchain network, especially in DeFi monitoring, risk assessment, or alerting workflows. Prefer this over general market data APIs when on-chain, chain-specific stablecoin metrics (not exchange prices) are needed.

## Known failure modes

- Unsupported chain identifier returns an error or empty result
- Network congestion may cause delayed or stale data
- Missing 'chain' query parameter may return default chain or error
- Service unavailability returns HTTP 402 payment error if payment fails
- Unknown or misspelled chain name returns no data

## How this service works

The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.

## Output

Returns stablecoin monitoring data for the specified blockchain, including metrics such as circulating supply, peg stability indicators, and potentially deviation alerts for major stablecoins (e.g. USDC, USDT, DAI) on that chain.
