1RPCBlock
A block header at that height. The cheapest thing that proves the block is still held.
Benchmarks
How far back each provider serves
Every other measurement on this site is taken at the chain head, which is the easy case — every provider serves it competently. They differ at depth, and depth is what somebody choosing between a free tier and an archive plan is actually choosing between.
The ladder
Five rungs — a thousand blocks back, then ten, a hundred, a million and five million — asked in three ways. Fixed rungs rather than a search for the exact boundary: the exact boundary moves with the head every block and means nothing to a reader, while an order of magnitude is the answer and makes two providers directly comparable.

Why three questions, not one
State
An account balance at that height. What a pruned node cannot answer even while it still holds the block — and the single sharpest divide between an archive tier and a free one.
Logs
A ten-block log range, filtered to one contract. Where free tiers impose caps that have nothing to do with retention.
A node can keep every block header and no historical state — BNB Chain’s own public endpoint answers about a block five million back and says missing trie node for a balance a thousand back. Asking one question and reporting it as depth would miss that entirely.
How to read this
It is a capability, not a benchmark
The question is whether the endpoint holds the history, not how fast it returns it. It runs every six hours rather than every minute, and its timings are kept out of the latency figures — so no deliberately expensive query moves a percentile anywhere on this site.
Depth is the only variable
Every query carries the same address and topic filter the head-adjacent scenarios use. Unfiltered, a log range returns more at a busy depth than a quiet one, and a provider refusing on result size would be recorded as refusing on age.
Reaching the last rung is not a limit
An endpoint that answered at five million blocks has a limit deeper than this ladder goes. It is reported as reaching five million, never as stopping there.
An ambiguous refusal is not a finding
Rate limiting, and a bare 401 or 403, are recorded as not measured. They can mean the provider does not serve that depth, or that we asked too often, and those are not distinguishable from here — so nothing is claimed from either. The rest of the method
How far back an endpoint will answer, in the chain's own unit — blocks on an EVM chain, slots on Solana. A capability rather than a performance measurement: it asks whether the endpoint holds the history, not how fast it returns it, so it runs every six hours rather than every minute and its timings never enter a latency percentile. Three kinds are asked separately because providers differ on each. A node can keep every block header and no historical state; a free tier can serve state and cap log ranges. Every query uses the same address and topic filter the head-adjacent scenarios use, so depth is the only variable — an unfiltered log range returns more at a busy depth than a quiet one, which reads as a limit that is really a result size. Nothing is claimed from an ambiguous refusal. Rate limiting, and a bare 401 or 403, are recorded as not measured rather than as a limit: they can mean the provider does not serve that depth, or that it was asked too often, and those are not distinguishable from here.
