Get your wallet balance for a specific currency. Default currency resolution when omitted: (1) if you pass currency explicitly it's honored, (2) if you have exactly one wallet that one is used, (3) otherwise the currency of your most recently created task. No stale USD default. Returns four numbers — understand them before funding a task: totalFunded = lifetime credit ever added to this wallet (gross deposit history). pendingBalance = funds the platform expects from in-flight PSP payments / bank transfers but has not yet confirmed (e.g. checkout in progress, IBAN deposit unreconciled). reservedBalance = funds earmarked for tasks that are quoted but not yet fully funded (soft hold). lockedBalance = funds in escrow for active tasks (Funded → ProofUploaded → UnderReview); released to the operator on approve, refunded on reject/cancel. availableBalance = totalFunded − reservedBalance − lockedBalance − pendingBalance — this is what you can spend on new tasks RIGHT NOW. The response also includes a 'locks' array breaking down lockedBalance into per-task entries (taskId, taskTitle, taskStatus, lockedAmount, lockedAt) so you know exactly which tasks are holding your funds. Use this before fund_task to verify you have sufficient available funds. For all currencies at once, use list_wallets. Requires authentication.
