Wyndham Hotels & Resorts
Wyndham Hotels & Resorts, Inc. (NYSE: WH) is the world's largest hotel franchising company by number of properties, with over 8,300 affiliated hotels and approximately 869,000 rooms across roughly 25 brands in 95+ countries, licensed to more than 6,200 franchisees. Headquartered in Parsippany, New Jersey, its home market is the United States. Wyndham does not operate most of its hotels — it franchises brands (Days Inn, Super 8, Ramada, La Quinta, Microtel, Baymont, Howard Johnson, Travelodge, Wingate, Wyndham, Wyndham Grand, Trademark Collection, TRYP, Dolce, ECHO Suites and others) and sells the demand that flows through them. It sits in the distribution chain as a franchisor and demand aggregator rather than as a distribution platform: inventory reaches buyers through Wyndham's own brand.com sites and Wyndham Rewards, through GDS chain codes under master chain code WR, and through third-party online travel agents, with the central reservation layer supplied by Sabre Hospitality's SynXis CRS under a relationship Sabre publicly renewed in July 2024. There is no travel API: no developer portal, no API documentation, no OpenAPI, and no property, rate, availability, reservation, loyalty or folio surface is machine-readable anywhere. developer., developers., docs. and api. subdomains do not resolve; /developers, /api, /docs, /openapi.json, /swagger.json and /api-docs all return 404, and mcp.wyndhamhotels.com resolves with a valid certificate but serves an Akamai 503 on every path. The Terms of Use (effective 2026-03-12) affirmatively prohibit robots, spiders, meta-searching and automated access, and separately prohibit automated access to Wyndham's AI Search. What a second enrichment round did find on 2026-07-28 is undocumented CMS infrastructure that is nonetheless genuinely live: www.wyndhambusiness.com and development.wyndhamhotels.com both run WordPress on WP Engine and leave the WordPress REST API anonymously readable (309 and 403 registered routes, with JSON Schema available by HTTP OPTIONS), and three WordPress MCP adapter routes are registered across the two estates — one of them, on www.wyndhambusiness.com, bound to a real OAuth 2.1 authorization server with RFC 8414 and RFC 9728 discovery metadata, mandatory PKCE S256 and a single `mcp` scope, returning a standards-correct 401 bearer challenge to anonymous callers. None of it is documented, supported, or usable without a credential Wyndham issues to no third party, and none of it carries hotel data. The integration surface that matters is still reached only through a franchise agreement, a commercial distribution agreement, or Sabre.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Wyndham Hotels & Resorts the way a machine reads it — 18 machine-readable artifacts across 3 APIs, 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 — Wyndham Hotels & Resorts scores 23.7/100 (emerging), with a separate agent-readiness read of 29/100 (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 Wyndham Hotels & Resorts
Each block below is one kind of artifact we hold for Wyndham Hotels & Resorts. 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 3
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.
Individual APIs this provider publishes, each with its own machine-readable definition.

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

This is an independent, third-party profile of Wyndham Hotels & Resorts, 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.
