🟢check_pool(pool_id, pool_address, chain, token_a, token_b, ...)
Use this when the user asks about one liquidity pool, such as "volume and fee APR for WETH and USDC on Ethereum" or "is this pool APR a spike?". Pass a pool id, or chain plus token_a and token_b (symbols or token addresses). Optionally pass a price range, holding_days, and gas or exit amounts for the fee-versus-IL estimate. Returns 1-day and 7-day volume and fee APR, TVL, an APR flag with a reason, a risk checklist with warnings, price trend, token risk flags when a public source covers them, and an informational position-type label. A pool contract address is not in the index: the answer says needs_tokens and what to pass instead. Not financial advice, and it does not recommend entering or leaving a position.

}🟢find_active_pools(chains, min_volume_usd_1d, min_fee_percent, limit)
Use this when the user wants pools across chains or DEXes with recent volume and a fee rate, such as "high fee pools on Base with real volume". Optionally pass chains, a minimum 1-day volume, a minimum fee percent, and a limit up to 8. Returns each pool's volume, TVL, fee rate, 1-day and 7-day fee APR, and an APR flag, highest fee APR first. It does not read token contracts or the current tick. Call check_pool with a returned pool id for token flags. Not financial advice.

}🟢estimate_lp(price_now, price_later, price_lower, price_upper, holding_days, ...)
Estimate fees versus impermanent loss. Use this when the user gives a price range or a later price, a holding period, and a fee APR, and wants to know whether fees cover impermanent loss, gas, and exit cost. Pass price_now, holding_days, and fee_apr_percent. Pass price_lower and price_upper for a concentrated range, or omit them for the full-range formula. Optionally pass price_later, capital_usd, gas_usd, and exit_cost_usd. Returns the formula, the fee fraction, the IL fraction, whether fees cover IL and the costs you passed, a plain break-even price line, and break-even prices from a sample. It does not look up gas or recommend a position. Not financial advice.
