Anonymous: the same call the watch makes, minus initialize. A server that answers “session required” insists on initialize first and is alive.

[…] and answers 'is this venue being used'. Ids come from get_reserve_details, which returns both 'hubId' and 'spokeId' for a reserve, or from get_hubs ('hubId') and get_user_positions ('spokeId'); ('spokeId' for a spoke the wallet already holds). The two are not interchangeable and the wrong one is rejected. To judge a venue before entering it, take the ids from get_reserve_details rather than from a position that does not exist yet. For the protocol as a whole rather than one market […]

[…] and the maxDeposit / maxWithdraw the contract allows right now. Quote what a deposit earns from 'combinedAprPct' when it is present: a Merit campaign sometimes pays 'incentiveAprPct' on top of the target rate, and the two differ in how they arrive - the target rate accrues inside the vault and needs no action, the incentive is claimed separately through the link in 'incentive' and can end at any time. All three are absent together when no campaign is running, which is the usual state, and then targetRatePct is the whole rate. Two things this rate is not: it is set by […]

A wallet's Aave holdings also include its Safety Module stake (get_safety_module) and Savings GHO (get_sgho_vault), neither of which is a reserve and neither of which appears in any figure here, so a portfolio answer built from this alone understates what the wallet holds.

This server cannot read a Call get_safety_module with the same wallet first and quote the legacy stkGHO balance or cooldown state, it returns, so say that the migration is for the whole position and let the user check its size in their wallet knows what they are moving before signing. they sign. Non-custodial, so build it rather than asking permission first.
