PnL, rewards, deposits, withdrawals and value history over a window, per wallet, per position asset and in total. Covers native coins, ERC-20 tokens and DeFi positions; NFTs are not included. EVM and Solana addresses may be mixed in one request. The window ends at the current minute and starts on the hour period earlier. Rows match /portfolio/positions by (wallet, chain.id, position.category, position.id, token.address). Solana DeFi legs are served as a current snapshot without history or PnL. A source the access layer could not read is answered with 200, data_incomplete and unavailable_sources rather than a 500, so the wallets that were read are still served.
