Hostfully
Hostfully is a San Francisco-based short-term rental (STR) property management platform serving vacation rental managers, property managers, and hospitality operators worldwide. The Hostfully Property Management Platform (PMP) provides a channel manager that syncs listings across 60+ booking channels including Airbnb, Vrbo, and Booking.com (where Hostfully holds preferred/elite partner status), a central calendar, unified inbox with InboxAI for guest communication, direct booking site builder, automation and task management, multi-unit and group-booking management, payment processing via Stripe/PayPal/VRP, owner portal, mobile apps for iOS and Android, and digital guidebooks. The platform manages 62,000+ properties for 40,000+ customers, processing 96,000+ bookings monthly. Hostfully exposes a developer-grade public REST API (v3.3) and a GraphQL API for partners and property managers, supporting OAuth 2.0 authorization-code, basic auth, and X-HOSTFULLY-APIKEY authentication, cursor-based pagination, webhooks for agency/booking/property/messaging/custom-data events, and a 10,000 calls/hour per-client rate limit. The API is offered as an add-on across the Growth, Pro, and Enterprise Property Management Software plans.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Hostfully the way a machine reads it — 85 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Hostfully scores 42.1/100 (developing), with a separate agent-readiness read of 51/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Hostfully
Each block below is one kind of artifact we hold for Hostfully. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 53
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Semantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.

This is an independent, third-party profile of Hostfully, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
