answers 402

Takes a piece of text and either turns it into leetspeak (swapping some letters for numbers and symbols, like 'hello' becoming 'h3110') or turns leetspeak back into normal, easy-to-read words. The same words always produce the same result, so answers never change unexpectedly.

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