9flats API
The 9flats read API over the marketplace's listing data: search places, fetch a place with its photos, prices, reviews and monthly availability calendar, and fetch a user with their favourites and (for the authenticated user) their bookings. Authenticated with OAuth 1.0a plus a client_id query parameter; responses are JSON envelopes keyed by resource name with links[] rel/href navigation and page-number pagination. Nine operations, all GET — no write surface is published. Reconstructed from 9flats' own client library, because the reference site the library points at has been withdrawn.
