Thumbtack Demand API
Marketplace-side ("Demand Partner") integration surface for helping customers find pros, explore service categories, and submit project requests - pro search by zip code/category, filtered pro matching, autocomplete, homecare checklists, category recommendations, and on-demand order management. v1/v2 routes use HTTP Basic auth; v4 routes use OAuth 2.0. Approval required; access is granted by Thumbtack after a partner application, not self-serve.
