200 Statistics for mempool transactions Schema — OPTIONAL tx_type_counts object Number of tranasction in the mempool, broken down by transaction type. token_transfer number smart_contract number contract_call number poison_microblock number tx_simple_fee_averages object The simple mean (average) transaction fee, broken down by transaction type. Note that this does not factor in actual execution costs. The average fee is not a reliable metric for calculating a fee for a new transaction. token_transfer object p25 number p50 number p75 number p95 number smart_contract object p25 number p50 number p75 number p95 number contract_call object p25 number p50 number p75 number p95 number poison_microblock object p25 number p50 number p75 number p95 number tx_ages object The average time (in blocks) that transactions have lived in the mempool. The start block height is simply the current chain-tip of when the attached Stacks node receives the transaction. This timing can be different across Stacks nodes / API instances due to propagation timing differences in the p2p network. token_transfer object p25 number p50 number p75 number p95 number smart_contract object p25 number p50 number p75 number p95 number contract_call object p25 number p50 number p75 number p95 number poison_microblock object p25 number p50 number p75 number p95 number tx_byte_sizes object The average byte size of transactions in the mempool, broken down by transaction type. token_transfer object p25 number p50 number p75 number p95 number smart_contract object p25 number p50 number p75 number p95 number contract_call object p25 number p50 number p75 number p95 number poison_microblock object p25 number p50 number p75 number p95 number
