data researchers

If you're interested in our data but not to receive bids as a proposer, or submit them as a builder, please use https://relay-analytics.ultrasound.money as the host.

standard routes supported across relays are described at: https://flashbots.github.io/relay-specs/#/Data .

we are happy to provide more on request. some undocumented APIs are available for common needs of other relays and builders.

servers are in EU. no rate-limits are implied but try not to exceed 100Mbit/s or so.

as our relay operates in multiple geographies it may take some seconds to minutes for data to appear in the aggregated view this URL offers through /relay/v1/data and /ultrasound/v1/data.
