⚪start_checkout(plan)
Open a billing URL for an explicitly selected eligible plan. After human confirmation, a Free account without a subscription receives a one-hour Stripe Checkout URL; an existing Basic subscriber receives Stripe billing management instead. Cancellation creates nothing and account identifiers are never accepted from the model.

}🟢get_usd_index(index)
Get the latest independently calculated USD index. dxy-reconstructed uses the published six-currency basket formula but is not official or licensed ICE data. usd-strength is the versioned exchangerate.dev equal-weight 13-currency index, with 2026-01-02 = 100. Both require a complete, time-aligned basket.

}🟡get_rate(base, quote, date)
Get the current — or historical, with date — exchange rate from one currency to another. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading. Rates update ~60s for real-time currencies through the trading week when the live overlay is active; the source field on every response is the authoritative freshness indicator (live | ecb_daily | fred_daily | nbp_daily) — rates fall back to official daily reference data during market closures, data-source unavailability, or low liquidity. market_session on every response indicates open, weekend, or interbank_closed.

Get a daily time-series of exchange rates over a date range (business days). Capped at 366 rows per call; when has_more is true, pass next_cursor as the cursor parameter to fetch the next page. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading.
