MEV Timing
Returns the MEV timing-game outcome for a single block: the winning relay bid, the earliest later bid that would have beaten it (first_better_bid), the highest-value later bid (best_later_bid), the value left on the table, and the winning relay and builder.
Resolve a block by number or the keywords “latest” / “finalized”. Pair this with /api/v2/ethereum/validators/proposal-slots to drill into a specific proposal.
Note: MEV relay and timing data is only available on mainnet at this time.
History: Relay bid collection began on 2024-06-03 (UTC). Blocks before that date — including all pre-Merge blocks — return status unknown, since the absence of relay data means the timing outcome is not known rather than that no MEV occurred.
Data freshness: per-slot relay statistics lag the chain head by roughly 4 hours. A block newer than the latest aggregated slot returns status pending until the data catches up.
