Aave yield and market analysis

Steps

1. get_markets with symbols for the assets in question, no chainId, version all. The symbol filter is what makes v3 cross-chain — unfiltered v3 reads Ethereum alone.
2. Shortlist, then per candidate: get_reserve_details for risk parameters and the rate curve, get_apy_history for how the spot rate has moved.
3. GHO savings questions: get_sgho_vault. Its rate is governance-set, not utilisation-driven, and sGHO is not collateral — present it as savings, not as a lending position.

Reporting rules

• State the coverage with the numbers: which chains were read (chainsCovered), which were not (chainsNotCovered), and that chainsNotServed chains hold no data here at all.
• Say whether the answer is a sample or the population. "Top 5 by APY" filtered from one call is a sample; only an unfiltered read of every covered chain supports "the best rate on Aave is…".
• Rank only enterable rates: skip rows flagged isFrozen / isPaused / cap-reached, and check suppliable / borrowable (v4) or availableLiquidity (v3) against the size in question. A great APY with no capacity is not an option.
• Spot APY is variable: for any recommendation, quote the recent range from get_apy_history next to the spot figure.
• v4 spokes sharing a hub share its rate — identical APYs across spoke rows are one underlying rate, not independent options.

Done when

• Every chain read is named, and every chain not read is named as not-read.
• The answer says whether it is a sample or the population; "the best rate on Aave" appears only behind an unfiltered read of every covered chain.
• Every ranked row is enterable, with its capacity checked against the size asked for.
• Every spot APY quoted for a recommendation carries its recent range beside it.
