Angi
Angi (formerly Angie's List, founded 1995) is a digital home services marketplace connecting homeowners with home service professionals for repair, maintenance, and improvement projects. Angie's List merged with IAC's HomeAdvisor in 2017 under parent ANGI Homeservices Inc.; in March 2021 the consumer brand and parent company were both renamed Angi, with HomeAdvisor continuing as the pro-facing "Angi Leads" lead-generation business. IAC fully spun off its stake in April 2025, making Angi Inc. (NASDAQ: ANGI) an independent public company. Angi does not operate a self-serve public developer portal or publish an API reference. It does offer a gated, partner-only lead-delivery mechanism: Angi Ads/Angi Leads pushes new homeowner leads as JSON to a webhook URL a pro's CRM provides (authenticated with an X-API-KEY header), and an OAuth-style "Sign in with Angi" account-linking flow used by a short list of approved CRM/field-service partners (ServiceTitan, Jobber) to receive lead and booking data. Both require a direct arrangement with an Angi Ads Client Success Manager rather than self-serve API keys.
