answers 402

Counts BGP updates for a prefix or an autonomous system in a recent window and compares them against a baseline built from a longer preceding period for the same resource. The comparison is deliberately self-referential: an AS with a hundred prefixes has a different normal than one with ten thousand, and a fixed threshold is blind for the first and a permanent alarm for the second.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
