Hostaway is an AI-powered vacation rental management platform that consolidates property management, channel management, direct booking, guest messaging, automation, and revenue optimization for short-term rental operators. The platform connects to Airbnb, Vrbo, Booking.com, Expedia, Google Vacation Rentals, and Marriott Homes & Villas, and exposes a documented OAuth 2.0 public REST API at https://api.hostaway.com/v1 covering listings, reservations, calendar, messaging, finance, tasks, custom fields, guest payments, and unified webhooks. Pricing is quote-based; a free product demo is available. The Hostaway Marketplace contains 100+ integrated vendors spanning revenue management, operations, smart locks, payments, and accounting.
Hostaway is listed with 16 APIs on the APIs.io network, including Listings API, Reservations API, Calendar API, and 13 more. Tagged areas include Vacation Rentals, Short-Term Rental, Property Management, Channel Manager, and Airbnb.
The Hostaway catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Hostaway’s developer surface includes authentication, developer portal, documentation, signup flow, pricing, getting-started guide, engineering blog, and 23 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
MCP Server+12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples+7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
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.
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.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
