Read a liquidity pool's volume, TVL and fee APR over 1 and 7 days, and spot a short APR spike.

Use this when the user asks about one real liquidity pool, such as "volume and fee APR for WETH and USDC on Ethereum" or "is this pool APR a spike?". Pass pool_id (a DefiLlama UUID), or chain plus token_a and token_b, for example chain "ethereum", token_a "WETH", token_b "USDC". Do not try pool_address first: the open index has no pool contract addresses, so it always returns needs_tokens. 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. Symbols for one token pair with several fee tiers or exchanges return the highest-TVL pool, with the others in other_tiers. Symbols that match different tokens return status ambiguous. The optional range fields (price_lower, price_upper, price_now, holding_days, capital_usd, gas_usd, exit_cost_usd) add the same fee-versus-impermanent-loss estimate as estimate_lp, at this pool's fee APR. For a pure what-if with no pool, use estimate_lp.
Chain name or short alias, used with token_a and token_b: ethereum, base, arbitrum, optimism, polygon, bsc, avalanche, solana, zksync, linea, gnosis, scroll, mantle, celo, sonic, or sui. Aliases such as eth, arb, op, bnb, matic, avax, and sol also work
Gas you expect to pay to enter and exit, in the same currency as capital_usd
DefiLlama pool id, a UUID such as "b99bcdf5-1350-4269-981e-0e9b5cccb007", from find_active_pools or other_tiers. Send it alone
First token symbol or contract address, such as "WETH" or "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2". Needs chain and token_b
Second token symbol or contract address, such as "USDC"
Current price in the same units as the range
Position size, so gas and exit cost can be compared with fees. Not stored as a record of who asked
Lower price of the range, in quote per base
Upper price of the range, in quote per base
Holding window for the fee-versus-IL estimate. Requires price_lower, price_upper, and price_now
Pool contract address. The open yields index has no pool contract addresses, so this always returns needs_tokens. Prefer pool_id, or chain with token_a and token_b
Other exit cost, such as a withdrawal fee, in the same currency as capital_usd

}Estimate fees versus impermanent loss. Use this when the user gives numbers for a what-if and wants to know whether swap fees cover impermanent loss, gas, and exit cost. It needs no pool and reads no live data. Pass price_now, holding_days, and fee_apr_percent, for example price_now 2500, holding_days 14, fee_apr_percent 40. Add price_lower and price_upper for a concentrated range, or omit both for the full-range formula. Optionally pass price_later, capital_usd, gas_usd, and exit_cost_usd. Returns the formula, the fee fraction, the impermanent loss fraction, whether fees cover it 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. To read a real pool's volume and fee APR, use check_pool.
| Argument | Type | Description |
|---|---|---|
| gas_usd | number | Gas you expect to pay. Not looked up |
| price_now* | number | Current price, quote token per base token, such as 2500 for ETH in USDC |
| capital_usd | number | Position size, so gas and exit cost can be turned into a fraction of the position |
| price_later | number | A later price to score. Omit to get break-even prices and the range edges only |
| price_lower | number | Lower bound of a concentrated range. Omit, with price_upper, for the full-range formula |
| price_upper |
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". All arguments are optional: chains, min_volume_usd_1d (default 50000), min_fee_percent (default 0.05), and limit (default 5, at most 8). Returns each pool's id, volume, TVL, fee rate, 1-day and 7-day fee APR, and an APR flag with its reason, highest 1-day fee APR first. A small pool with a one-day volume spike can rank first, so check tvl_usd and apr_flag before you lead with it, or raise min_volume_usd_1d. It does not read token contracts or the current tick. Call check_pool with a returned pool_id for token flags and the risk checklist.
| Argument | Type | Description |
|---|---|---|
| limit | integer | How many pools to return, at most 8. Default 5 |
| chains | array | Optional chain names, such as ["base"] or ["ethereum", "arbitrum"]. Supported: ethereum, base, arbitrum, optimism, polygon, bsc, avalanche, solana, zksync, linea, gnosis, scroll, mantle, celo, sonic, or sui. Omit to scan every chain in the index |
| min_fee_percent | number | Minimum swap fee in percent, not a fraction: 0.3 means 0.3%. Read from pool metadata. Default 0.05 |
| min_volume_usd_1d | number | Minimum 1-day volume in USD. Default 50000. Raise it, for example to 1000000, to skip small pools with a one-day spike |
