answers 402

NDJSON to a JSON array. POST newline-delimited JSON; the response is a pretty-printed array of the parsed values. Blank lines are skipped and a line that does not parse is refused naming the 1-based line number — which is the reason to run a parser over a log file instead of wrapping it in brackets.

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