Example prompt: Can you analyze the liquidity pool health for the WETH/USDC pair on Base chain and tell me if it's in good shape to trade?

## When to prefer this

Use this endpoint when you need to assess the health and safety of a Base chain liquidity pool before executing a swap or providing liquidity. Particularly useful when you have a token pair in mind and want to check depth and health before trading, or when you have a specific pool address and need a quick risk evaluation.

## Known failure modes

- Pool address not found or invalid — returns 404 or empty result
- Token symbols not recognized — returns error for unknown token addresses
- Pool does not exist on Base chain for the given pair — no data returned
- Payment not processed (402 error) — endpoint requires $0.01 USDC per call
- Network timeout or Render cold start delay — service may be slow to respond initially
