Example prompt: Can you look up the Uniswap V4 liquidity position details on Base mainnet for my position — I need the full position metadata and liquidity breakdown?

## When to prefer this

Use this endpoint when you need to query Uniswap V4 liquidity position data specifically on Base mainnet (or Base Sepolia for testing) and are comfortable paying $0.02 USDC per call via the x402 protocol. Prefer this over general blockchain explorers when you need structured JSON position data ready for agent consumption without manual parsing.

## Known failure modes

- Missing or invalid position properties input returns an error response
- Payment not provided or insufficient USDC on Base mainnet results in HTTP 402 payment required
- Invalid network parameter (not base or base-sepolia) may return an error
- Position not found for given parameters returns empty or error JSON
- Cloudflare Worker timeout if Base mainnet RPC is slow
