Returns the AI-generated summary (headline, tl;dr, what/who/why/cost - automatically checked before publish and clearly labeled when present), the official status in plain language, a decision_state (pending, settled or enacted, with the official record's own sentence in settled_reason once the decision is settled or enacted), an urgency band and an urgency_score (the score is ranked from status and recency alone; decision_state, not the score, says whether a decision is still ahead), sponsor, key dates, the official Congress.gov page, and - while the decision is still pending - an act_url to Oravan's on-site call flow. This tool never drafts a phone script - script generation happens only on-site, where the caller reads and can edit the script before dialing; that is not available over this API.",
