Wahi is a Toronto-headquartered Canadian digital real estate platform and licensed brokerage — Wahi Inc., trading as Wahi Realty Inc., Brokerage — founded in 2021 by Benjy Katchen. It runs a consumer home search, an instant home valuation estimate, market data products (Market Pulse, House Price Index), a Wahi Select REALTOR matching service and a cashback program across Ontario, British Columbia, Alberta, Nova Scotia, Saskatchewan and New Brunswick. Wahi sits in the challenger layer of the Canadian listings value chain and does not own the data it surfaces: Canadian residential listings run through CREA, the single national cooperative that operates REALTOR.ca and the Data Distribution Facility (DDF), and Wahi reaches that data as a member brokerage and through a commercial MLS connectivity vendor (Repliers) rather than by operating a feed of its own. Wahi runs no developer programme: there is no developer portal, no api./developer./developers./docs. subdomain (all fail DNS resolution), no API key or OAuth credential path, and no RESO Web API certification, RESO Data Dictionary certification, OData service or $metadata document anywhere on its hosts — Wahi appears in neither the RESO certificates directory nor RESO's Canadian membership roster. The Terms of Use expressly forbid automated access, crawling and scraping, and forbid collecting, copying, storing or redistributing MLS data. It does, however, publish two agent-facing artifacts that a portal-shaped search misses: a 421KB llms.txt at https://wahi.com/llms.txt (Last-Updated 2025-07-20) and an OpenAI-style AI plugin manifest at /.well-known/ai-plugin.json that points to a genuine OpenAPI 3.0.1 "Listing Search API" at https://wahi.com/gpt/openapi.yaml — one anonymous searchListings operation with 30 typed filters over Canadian listings. The spec is still served; the server it names, api.prod.wahi.com/gpt, returns 404, so the contract is published but unserved. A live Apollo GraphQL endpoint exists at api.prod.wahi.com/graphql with introspection disabled and robots.txt disallowing it, and the stock WordPress REST API of the marketing CMS remains anonymously callable. Wahi is overwhelmingly an API consumer rather than a producer, but not a zero.
Wahi publishes 1 API on the APIs.io network: Listing Search API. Tagged areas include Real Estate, Canada, Property Listings, MLS, and Valuation.
Wahi’s developer surface includes authentication, support, engineering blog, and 16 more developer resources.

description: 'The stock WordPress REST API served by Wahi''s marketing and Learning Centre CMS at https://wahi.com/wp-json/.
It is publicly reachable and self-describing: an anonymous GET on the root returns a 319KB JSON discovery document declaring
14 namespaces and 223 routes (wp/v2 content routes plus oembed/1.0, contact-form-7/v1, rankmath/v1, divi/v1, divi-pixel/v1,
custom-permalinks/v1, wp-block-editor/v1, wp-smush/v1 and wp-site-health/v1 plugin routes), and an anonymous GET on /wp-json/wp/v2/posts
returns published Learning Centre content as JSON. This is CMS infrastructure that Wahi neither documents nor offers as
a product — it carries no Wahi developer documentation, no key issuance, no terms of API use and no real estate listing,
valuation or transaction capability. It is recorded here because it is the only genuinely public, machine-readable API
surface confirmed on a Wahi host. Write operations advertise WordPress application passwords, which are issued only through
wp-admin to authenticated CMS users.'

description: 'Wahi''s own real estate API, and the only machine-readable contract it authors. Discovered through https://wahi.com/.well-known/ai-plugin.json,
an OpenAI-style AI plugin manifest that points at https://wahi.com/gpt/openapi.yaml — a genuine OpenAPI 3.0.1 document
(HTTP 200, 12,574 bytes on 2026-07-26) titled "Listing Search API". It declares one operation, searchListings (GET /search),
with 30 typed query parameters covering geography (lat/long plus a distance radius in metres, or a free-text search string),
price in CAD, bedrooms, bathrooms, property type, sale versus rent, square footage, lot dimensions, parking, amenities
(garage, fireplace, air conditioning, pets) and Fraser Institute school ratings, plus an `active` flag that switches the
result set between active and sold listings. It returns a ListingsResponse of Listing objects keyed on the board''s mlsId.
It requires no authentication: the spec declares no securitySchemes and the manifest declares auth type "none". Two caveats
are material. First, the declared server https://api.prod.wahi.com/gpt is currently dark — /gpt/search returned HTTP 404
{"message":"Not Found"} when probed on 2026-07-26 — so this is a published-but-unserved ChatGPT-plugin-era contract, retired
with no Sunset header, deprecation notice or changelog. Second, the data is licensed: listings originate with CREA and
the Canadian real estate boards and Wahi''s Terms of Use forbid storing or redistributing them.'
