## 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-token-holders-lookup-e3654d31
```

Example prompt: Who are the token holders for the contract address 0xAbCd1234... on Base? I want to see the full holder list with balances.

## When to prefer this

Use this endpoint when you need on-chain token holder data across Base, Arbitrum, or Solana and want to pay per-call via x402 micropayments without a subscription. Prefer this over block explorer scraping when you need programmatic, structured holder data for AI agent workflows.

## Known failure modes

- Invalid chain identifier returns an error or empty response
- Malformed or non-existent contract address returns no data
- Unsupported chain returns error
- Rate limiting or payment failure via x402 micropayment returns 402
- Contract with no holders returns empty list
- Network timeout on heavily queried chains

## How this service works
