## 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 ragradar-stablecoins-on-chain-data-31b6fff5
```

Example prompt: Pull the latest on-chain stablecoin data from RagRadar — I want to see what stablecoins are active on Base and their key metrics.

## When to prefer this

Choose this endpoint when you need structured on-chain stablecoin data from EVM chains (Base, Arbitrum) or Solana and are comfortable with x402 micropayment at $0.01 USDC per call. Ideal for AI agents that need real-time or recent blockchain stablecoin intelligence without managing a full node or indexer.

## Known failure modes

- 402 Payment Required if x402 micropayment not provided or USDC balance insufficient
- Invalid or malformed properties parameter returns 400 or empty result
- Unsupported chain or stablecoin query returns empty data set
- Network timeout or upstream chain RPC failure returns 503 or error status
- Rate limiting if too many requests in a short period
