Current CD APYs: FDIC national averages by term plus RateZip-observed institution rates (with terms, minimums/conditions, observation timestamps, sources, and staleness status). Pass term_months (e.g. 3, 6, 12, 24, 36, 60) to filter to one term; omit for all terms grouped by term. Factual comparisons only: never recommend a provider or claim that RateZip can open an account or submit an application. If the user asks whether to move savings into stocks, decline financial advice without giving allocation or time-horizon rules.
Input schema

| state | string | no | Two-letter state — adds an availability/eligibility note |
| credit_score | integer | no | FICO — deposit APYs generally don't vary by credit; returns a clarifying note only |
