How big is this endpoint among the ones like it?

1 call100,000this endpoint
Calls counted in the trailing thirty days across the 162 endpoints in Randomness that carry counters, binned on a logarithmic scale because the range runs over five orders of magnitude. The marked bin is this endpoint, at 2: 76 in the category are counted higher and 85 lower.

No trace is drawn of this endpoint’s own volume. Its counters have changed 1 time across 36 observations, and 3 changes are the fewest this site will draw a trace through, because two points and a guess are not a series. Every observation is in the JSON.
