## 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 speraxos-token-holders-api-aa04215d
```

Example prompt: Show me the current token holders for the USDC contract on Base — I want to see who the top wallets are and how concentrated the ownership is.

## When to prefer this

Use this endpoint when you need on-chain token holder data for a specific DeFi token on Base without managing API keys — ideal for agents that can pay per-request in USDC via x402. Prefer this over general blockchain explorers when you need structured, AI-ready holder data integrated into a DeFi intelligence workflow.

## Known failure modes

- Invalid or unrecognized token contract address returns an error or empty result
- Payment not included or insufficient USDC via x402 returns a 402 Payment Required response
- Token exists on a different chain than expected, resulting in no holders found
- Rate limiting or upstream data unavailability may return a timeout or 503 error
- Malformed request parameters return a 400 Bad Request

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns a list of wallet addresses holding the specified token, along with their balances and share of total supply, enabling analysis of holder count, distribution, and whale concentration.
