answers 402

One RFC 3161 timestamp receipt over a digest you supply. No account and no API key: the response is the whole deliverable. Your data is never sent - only its hash - and nothing about the request is retained here.

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