Example prompt: Can you pull the current Alien V3 pool data from Cambrian for the ETH/USDC pair on the EVM chain — I need to see the liquidity and pricing info?

## When to prefer this

Choose this endpoint when you need Alien V3 DEX pool data on EVM chains via a pay-per-use model with no subscription required. Ideal for autonomous agents that need on-demand liquidity pool lookups without committing to a monthly API plan, and when x402 micropayment infrastructure is already in place.

## Known failure modes

- Missing or invalid query parameters returning empty array
- Payment failure via x402 if USDC balance insufficient
- Unsupported chain identifier returning no results
- Rate limiting or quota exhaustion on the pay-per-call model
- Pool not found for given token pair returning empty array

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

Returns an array of Alien V3 liquidity pool records from EVM chains, typically including pool addresses, token pairs, liquidity figures, pricing data, and other pool-level metrics relevant to DeFi analysis.
