Measured tools (16)

• get_top_rates read-only

  Return top SwitchWize rates with freshness and attribution. Savings, CDs, checking and money market answer only from their editor-approved snapshot. A category with no approved release yet returns no ranked rates and says so (approval_status: not_yet_approved) rather than serving unverified observations; approvedOnly makes that requirement explicit. Approved responses include product terms and field evidence; stale or unavailable releases return no ranked rates. detail=full (savings) adds the complete shared build: every listed account marked verified or tracked, best picks, movers, history and a headline summary.

  Parameters:

  • category (required) — string — Rate category, e.g. savings, cds, money-market, checking, mortgage.
  • limit — integer
  • detail — string — summary (default) adds list_counts. full (savings) adds the complete shared build: accounts (verified and tracked, each marked), best_picks, movers, history and summary. rates stays verified-only either way.
  • approvedOnly — boolean — Require an editor-approved deposit snapshot. Savings, CDs, checking and money market always answer from their own approved release; a category with no release yet returns no ranked rates (approval_status: not_yet_approved), as do stale or unavailable releases.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_top_hysa_rates read-only

  Return top high-yield savings rates with freshness and attribution. Answers only from the editor-approved snapshot; before its first release it returns no ranked rates and says so (approval_status: not_yet_approved). approvedOnly makes the requirement explicit. detail=full adds every listed account marked verified or tracked, best picks, movers, history and a headline summary.

  Parameters:

  • limit — integer
  • detail — string — summary (default) adds list_counts. full (savings) adds the complete shared build: accounts (verified and tracked, each marked), best_picks, movers, history and summary. rates stays verified-only either way.
  • approvedOnly — boolean — Require an editor-approved HYSA snapshot. The default tool already answers only from the approved release; before its first release it returns no ranked rates (approval_status: not_yet_approved).

• get_bank_gap read-only

  Estimate annual savings interest forgone for a supplied balance and optional bank name. comparisonApy is the average of the top three tracked savings rates, not an average across all banks; bankCount is the size of the tracked set. baselineApy is the named bank's APY, or the national savings benchmark when no bank is supplied. Return annualGap, APYs, observation date, freshness and methodology. This is a hypothetical estimate, not guaranteed savings or an account recommendation; verify eligibility, fees and current provider terms.

  Parameters:

  • bank — string — Optional bank name for user-facing context.
  • balance — number

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• compare_switch_savings read-only

  Compare a user's current APY with SwitchWize's current top savings APY for a balance.

  Parameters:

  • currentApy (required) — number
  • balance — number

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_rate_freshness read-only

  Return public data source freshness status and affected routes.

  Parameters:

• get_index_dataset read-only

  Return a SwitchWize index dataset summary and recent series.

  Parameters:

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_reality_score read-only

  Estimate the modeled annual value of a supported premium credit card for a consumer segment. Supply a card slug or name and optionally a segment ID; the default is occasional-traveler. Return segment assumptions, score, rewards, credits, perks, fee, interest, friction, net value, caveats, sources, verification date, freshness and methodology. Gross recovered value is rewards + credits + perks. breakageMultiplier is gross recovered value / advertised value, NOT divided by annual fee. feeRecoveryMultiplier is max(0, gross recovered value - interest drag - rewards friction discount) / annual fee, before subtracting the fee. Friction applies to raw rewards only. Reality Score is 100 * net realized value / advertised value. Ratios are rounded. These are scenario estimates, not personalized advice or guaranteed benefits. Preserve stale or unavailable labels; do not infer that all terms share the observation date. Unknown cards or segments return a structured error with suggestions.

  Parameters:

  • card (required) — string — Card slug or name, e.g. platinum-card or Chase Sapphire Reserve.
  • segment — string — Optional segment id, e.g. occasional-traveler, small-business-owner, balance-carrier.

  Return verified CD rollover rules for one bank, or every bank SwitchWize has verified: what happens automatically at maturity if the customer does nothing, the grace period, how to stop the rollover, and the early-withdrawal penalty. Each fact is sourced directly from the bank's own disclosure; an unverified field is omitted, never guessed.
