Ask a question with sources from your base.

Ask about one base owned by the current personal account. Up to five retrieved excerpts go to our AI service. No web search, tools or external actions. Generation costs USD 0.01 after explicit authorization. No retrieval match returns unsupported without a charge. The same question and selected source versions reuse the saved purchase. Responses cite document ID, version, content hash and an exact excerpt. Removed or replaced sources produce stale without revealing the old answer. Processing uses the existing private base stream; get_base also returns the latest answer. Check citations before reuse. Returns: { answer{id,question,status,statements,created_at?,charged?} }
