Answer questions from your own pages

How to do it

Offer /ask?query=… over GET and POST, as the NLWeb project does. Answer only from your own pages, and return the source URLs with the answer. NLWeb's own format returns a results list of schema.org items. List the endpoint in llms.txt, because no link relation for it is registered. NLWeb is an open project started by Microsoft, with no stable release, so treat its format as an early proposal.

Example

GET /ask?query=do+you+fix+skylights HTTP/1.1
Host: example.com

HTTP/1.1 200 OK
Content-Type: application/json

{"query":"do you fix skylights","answer":"Yes, we repair and replace skylights.","sources":["https://example.com/services"]}

How to check

Ask three questions your pages answer and one they don't. Each answer cites sources that answer 200, and the fourth says it has no answer.
