Houzz

Houzz is a home renovation and design platform that connects homeowners with home professionals, products, and design inspiration, and operates Houzz Pro, an all-in-one business management SaaS for contractors and design professionals (3D floor plans, takeoffs, estimates, invoices, scheduling, CRM, and marketing). For commerce, Houzz runs a marketplace and exposes an official Seller/Vendor Commerce API (opened to third-party partners in 2016) that lets merchants sync product listings, inventory, pricing, and orders. API access is gated: sellers enable it under Settings > API in the Houzz dashboard or request it via sellerapi@houzz.com, then authenticate integrations with an App ID, Token, and User Name. Houzz does not publish a general-purpose public developer portal, OpenAPI spec, or first-party SDKs; integration is handled through the Seller/Vendor programs and Houzz Pro's pre-built integrations (QuickBooks, Zapier, Gmail, Google Calendar/Drive, Gusto).

Houzz is listed with 1 API on the APIs.io network. Tagged areas include Company, E-Commerce, Marketplace, Home Improvement, and Interior Design.

Houzz’s developer surface includes API reference, support, engineering blog, pricing, signup flow, authentication, and 6 more developer resources.

scored 2026-10-09 · rubric v0.23.0
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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/houzz: open an issue to ask a question, or submit a pull request to add artifacts.
