Query raw EVM logs with address/topic filters, common event aliases, earliest/latest scanning, and optional inline decoding. COMMON USER ASKS: - Recent USDC Transfer logs - First recent USDC Transfer log - Latest ERC721/pass mint ID and tx hash FIRST CHOICE FOR: - NFT or ERC721 mint lookups such as latest pass minted, token ID, and mint transaction hash - contract event questions where the user needs exact event evidence rather than wallet or transaction summaries WHEN TO USE: - You need event logs filtered by contract or topic signature. - You want decoded log hints while still keeping the raw log shape available. - You want the first or last matching event in a bounded block/time window. - You want common event names such as transfer, approval, swap, mint, or burn instead of remembering topic0 hashes. - You need the latest ERC721/pass mint in a bounded deployment/recent window: filter Transfer events with topic1 as the zero address, use scan_order=latest, limit=1, and decode=true to expose decoded_log.decoded.token_id plus transaction_hash. DON'T USE: - You only want token transfers, which are easier with the token-transfer tool. EXAMPLES: - Recent USDC Transfer logs: {"network":"base-mainnet","timeframe":"1h","token_symbols":["USDC"],"event":"transfer","limit":20} - First recent USDC Transfer log: {"network":"base-mainnet","timeframe":"1h","token_symbols":["USDC"],"event":"transfer","scan_order":"earliest","limit":1} - Latest ERC721/pass mint ID and tx hash: {"network":"base-mainnet","from_block":46020000,"to_block":46100000,"addresses":["0xE4E70FdF2Fc1147a7f35c4c5de88E6BeA63eeAfA"],"event":"transfer","topic1":["0x0000000000000000000000000000000000000000000000000000000000000000"],"scan_order":"latest","decode":true,"include_transaction":true,"limit":1} - Decode logs inline: {"network":"ethereum-mainnet","timeframe":"1h","topic0":["0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef"],"decode":true,"limit":10}
