I want one informational library call through Call4me. My chosen branch is [branch], my visit date is [date], and my quiet laptop work window is [local start and end time with timezone]. Read that branch's official SFPL page to verify its number and hours, and read the study room policy. Check Call4me access with a balance request, without dialing. Prepare questions about adult general seating for a personal laptop, outlet locations and guest WiFi login. Do not ask for a guaranteed seat, a room reservation or permission to take a business call inside the library. Show me the selected branch, published number and source, exact questions, caller identity from my profile and a four minute call limit. Ask for approval of that single call and wait. After I approve, check the current general category requirements, use the live tool schema and call once with call4me_place_call.max_minutes set to 4. Do not reserve, buy, leave voicemail, arrange a callback or share contact details beyond the identity I approved. Follow the same returned call ID with call4me_get_call until the call ends, collect its transcript and retrieve available evidence with call4me_get_recordings, and return who answered, each answer, unresolved questions and the result links. If access or call delivery fails, report that failure without claiming an answer.
