What you'd call

4 endpoints, one key.

POST/v1/parity: One hotel and stay: the direct public, member and points rates beside the lowest public and member price on Booking.com, Expedia, Hotels.com, Trip.com and Agoda, each channel's gap to direct, the cheapest channel and the deepest undercut. Compared per night after tax.
POST/v1/compset: Up to 25 hotels of a chain for one stay, lowest public and member rate per hotel. A native batch on Marriott, Choice, Radisson, Wyndham, Best Western and Meliá; a paced fan-out elsewhere.
POST/v1/calendar: The lowest rate per night over a window for one hotel — a month of a competitor's pricing through the chain's own calendar where it has one.
POST/v1/watch: A signed webhook when an OTA sells the same nights under the direct public rate by at least the percentage you set — the parity alert, refreshed on your schedule, charged per refresh.

Every endpoint is in the API reference; the request bodies are the Zod schemas the gateway validates with.

A month in credits

A ten-hotel portfolio, watched daily.

Weights are the ones the gateway bills with; a result served from a recent cache is a quarter of the live price, and errors cost nothing.

FAQ

Revenue managers: questions before the first call

What is rate parity, and why would an OTA be cheaper than the hotel?

Rate parity is the hotel's promise — to its guests and in its OTA contracts — that its own site is never undercut. It breaks all the time: wholesale rates resold through an OTA, an OTA funding a discount from its own commission, a member price the hotel forgot to match. /parity finds those cases without opening five tabs per hotel: one call per hotel per date, cheaper = channel filters the undercuts, max_undercut_pct ranks them.

Is the comparison apples to apples?

Per night, after tax, wherever both sides carry an after-tax figure; comparison_note says when a side is native (Agoda in the example above), so its gap is off by that side's taxes and fees. Public rates only: an OTA's Genius or Member Price is reported in its own field and never enters the gap.

How fresh is it, and what does an error cost?

Live at request time, or from a cache a few minutes old — every response says which in source and cache_age_sec, and a cached answer bills a quarter of the live price. Errors, a hotel code the chain does not know and an OTA with no listing for the hotel cost nothing.

Start with 250 credits a month. No card, no call.

Every response states its own price in X-Credits-Charged; the playground runs any of these calls with no code.
