Is this paid endpoint answering right now?

Is this paid endpoint answering right now? Returns whether it serves a payment challenge, how many well-formed priced offers it carries, which warnings would actually break a payment as opposed to merely making the call harder to construct, and a single payable_now flag. Reports only what was observed; it makes no judgement about the seller.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
