Check a captain's or boat's availability. Provide exactly one of captainSlug or boatId. Omit date to get available dates for the next 90 days; provide both date (YYYY-MM-DD) and durationHours to get bookable time slots for that date. Only departures that have not yet left (Chicago time) are listed, so a past date has no slots. Each slot lists its offeredDurations, and every entry carries the durationId to pass to get_quote, create_booking, or create_boat_rental (null means that length is offered but not bookable through the API). A captain trip that lists harborIds departs only from those harbors (ids as in get_captain's harbors): create_booking refuses any other harbor for that trip. Without harborIds, drive time rules out none of the captain's active harbors.
DiscoveredBook a bareboat boat rental. A boat with Instant Book on returns a Stripe Checkout link (payment.kind checkout_link) for the charterer to complete payment. For a boat whose owner reviews every request first (get_quote's instantBook: false), a request is sent instead: nothing is charged, the result is a request with the estimated total and deposit, and if the owner accepts, the charterer is emailed a link to pay. Requires captainChoiceRightAcknowledged: true (the charterer affirms their right to choose their own captain). Optionally attach a partner/affiliate code; partnerCode can't be used on a request (PARTNER_CODE_NOT_AVAILABLE_FOR_REQUESTS).
DiscoveredBook a charter with a captain. A captain with Instant Book on returns a Stripe Checkout link (payment.kind checkout_link) for the charterer to complete payment. A captain who reviews every request first (get_quote's instantBook: false) is sent a request instead: nothing is charged, the result is a request with the estimated total and deposit, and if the captain accepts, the charterer is emailed a link to pay. Optionally attach a partner/affiliate code to credit a referrer; partnerCode can't be used on a request (PARTNER_CODE_NOT_AVAILABLE_FOR_REQUESTS). harborId must be a harbor this captain departs from: one of get_captain's harbors, or any list_harbors harbor when get_captain lists none. create_booking refuses any other harbor with HARBOR_NOT_OFFERED, and that error's harbors field lists the ones the captain departs from.

DiscoveredGet a captain's full profile by tenant slug, enriched with a rating summary and the most recent reviews.
DiscoveredGet a non-binding price quote (in cents) for a charter or rental. Provide exactly one of captainSlug or boatId, plus durationId and partySize. Pass `date` (YYYY-MM-DD) whenever you know it: the rate then comes from the operator's rate card for that day — weekday vs weekend vs holiday, including any per-date price the operator set — so the quote matches what checkout charges. Without a date, pass pricingTierId instead; the quote then reflects that tier and may differ from checkout for the actual day. Optionally pass a partnerCode to preview a discount. Returns currency, totalCents, depositCents, balanceCents, pricingModel, instantBook, and (when a code is given) a discountPreview. instantBook says what booking does: true → create_booking / create_boat_rental return a Stripe Checkout link; false → the operator reviews every request first, so booking sends them a request instead (nothing is charged until they accept, and partnerCode can't be used — the quote then prices no discount and its discountPreview says PARTNER_CODE_NOT_AVAILABLE_FOR_REQUESTS).
