## 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-usdc-holder-concentration-on-solana-7ef3304b
```

Example prompt: Can you check how concentrated USDC holdings are on Solana right now — specifically what share the largest accounts control and whether the float is dominated by a few whales?

## When to prefer this

Choose this endpoint when you need real-time, on-chain USDC holder concentration data specifically on the Solana network, without managing API keys or accounts — paying only per call in USDC via x402. Prefer this over general blockchain explorers when you need structured, agent-ready JSON output about float concentration and whale dominance for risk assessment or market analysis.

## Known failure modes

- Helius RPC downtime returns upstream error or empty response
- Invalid format query parameter returns 400 or unexpected response shape
- Payment not accepted or USDC transaction fails returns 402
- Rate limiting or network congestion on Solana may delay response
- Stale data if Helius RPC indexing lags behind chain state
