FillBench
Measured crypto exchange API latency with raw files
What it is
A public benchmark that times round trips to crypto exchange market-data APIs from one fixed US East server and publishes the median and the slow tail beside the raw JSON. Related pages measure on-chain payment settlement and the cost of a trade, and the latency tables use a Creative Commons attribution license. Developers picking an exchange API for a bot, and writers who want a rerunnable table, are the audience. The clock is a single region and the table is replaced on a schedule, some venues refuse that datacenter, and the project does not offer a trading or price API of its own.
