profileAPI
profileAPI is a B2B people and company data API built by Truebase, offering profiles with AI-inferred traits and signals for developers building sales and data products.
Updated October 2026
Overview: What is profileAPI?
Its website and documentation now redirect to truebase.io, which sells a managed AI go-to-market service starting at $3,000 a month (checked October 2026).
Truebase launched profileAPI as an extension of its own data, aimed at developers who wanted people and company profiles through a REST API instead of building scrapers and cleaning pipelines. Independent directories describe weekly updated profiles with inferred traits and real-time signals. Today the profileapi.com pages all land on Truebase's homepage, and no separate API pricing or docs are public.
Fit: Ideal customer profile.
Existing profileAPI users and developers who want Truebase data. New buyers looking for a self-serve people data API won't find sign-up, pricing or docs on the site any more, and Truebase's current offer is a managed service with an assigned Truebase specialist, not an API plan.
