Holidu
Holidu is a Munich-based vacation-rental search engine and short-term-rental technology company that helps travellers find and book holiday homes and helps property owners and managers distribute their inventory. Holidu exposes a public Developer Hub with two production REST APIs: the Affiliate API, for searching offers, retrieving property details, checking real-time availability and syncing changes; and the Connectivity (provider) API, a v2 property-management surface of ~50 operations covering apartments, multi-unit listings, descriptions, photos, facilities, reviews, rates, length-of-stay pricing, availability, extra costs, discounts, booking terms, payment and cancellation configuration, and bookings. Authentication is via per-partner API keys (with an OAuth 2.0 security service and Bearer-JWT callbacks), sandbox and production hosts are separated, and Holidu runs a HackerOne bug-bounty program. Holidu is backed by EQT Ventures, HV Capital and Northzone.
Holidu publishes 23 API contracts indexed on the APIs.io network, including Apartment API, Availabilities API, Availability API, and 20 more. Tagged areas include Company, Travel And Leisure, Vacation Rentals, Short-Term Rental, and Hospitality.
The Holidu catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
Holidu’s developer surface includes documentation, API reference, getting-started guide, changelog, support, signup flow, authentication, and 28 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Hospitality Technology (hotels, PMS, channel managers) | undeclared | - | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
