```

Example prompt: Can you pull the treasury stack data for this Base protocol — I want to see the token holdings, wallet breakdown, and any contract details associated with it?

## When to prefer this

Choose this endpoint when you need pay-per-call on-chain treasury and research data on the Base network without a subscription, especially when querying token holdings, wallet composition, or contract data for DeFi protocols. Best suited for agents that need lightweight, cost-controlled blockchain data access via x402 micropayments rather than a full-featured blockchain data provider subscription.

## Known failure modes

- Payment failure if USDC balance is insufficient for the $0.01 x402 micropayment
- Invalid or missing query parameters returning an empty or malformed stack object
- Queried address or contract not found on Base returning an empty stack
- Rate limiting or network timeout from the publicvm.com host
- Malformed input schema causing a 400-level error
