## 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 losbeto-holder-concentration-4c552b43
```

Example prompt: Can you check the holder concentration for the token PEPE on Ethereum — I want to know if it's whale-dominated or has a healthy distribution across wallets?

## When to prefer this

Choose this endpoint when you need on-chain holder distribution analysis for crypto assets without managing API keys or subscriptions — particularly useful for quick pre-trade risk checks or DeFi due diligence. It pays per call via USDC on Base or Solana (x402), making it ideal for agents that only need occasional holder concentration lookups rather than a full analytics platform subscription.

## Known failure modes

- Unknown or unsupported token symbol returns an error or empty result
- Token contract address not found on specified chain
- Payment failure via x402 (insufficient USDC balance or wrong network)
- Rate limit or service unavailability returns a non-200 response
- Newly launched token with insufficient on-chain data may return partial results

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana and Algorand via x402.

## Output

A JSON object containing holder concentration metrics for the requested asset, including distribution of ownership across wallet tiers (top 1, top 10, top 100 holders), percentage of supply held by whales, and potentially a concentration index score such as Gini coefficient or HHI.
