## Check the fit for your task

Before reading or paying, send your task with the report's question. The reply is JSON: {"state": "Covered" | "Partial" | "Not covered", "why": "..."}. Partial and Not covered mean the report is about your subject but not your question, or about another subject.

POST https://notthelivesite.com/api/task-fit
Content-Type: application/json
{"task":"<your task, in one or two sentences>","question":"What will Democrats' lead be in the congressional generic ballot on September 15, 2026?","summary":"As of 2026-09-08, the estimate for Democrats' lead on September 15 is +5.8 percentage points, with a plausible range of +3.0 to +8.5, conditional on using the RealClearPolling national generic-ballot average. The opened average displays Democrats at 48.1% and Republicans at 42.3%; this is a September 8 observation, not a September 15 result. The original question's resolution page could not be verified, so the choice of average remains an explicit assumption."}
