RB2B Enrichment API is one of 4 APIs that [RB2B](https://apis.io/providers/rb2b/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Enrichment, LinkedIn, Email, Phone, and Business Profile. The published artifact set on APIs.io includes API documentation.

Credit-metered Enrichment endpoints that take a known identifier — hashed email (MD5), plaintext email, or LinkedIn slug — and return additional B2B attributes: POST /hem_to_linkedin, /hem_to_best_linkedin, /hem_to_business_profile and /hem_to_maid (each accepting either an `md5` or an `email` key), plus /linkedin_to_hashed_emails, /linkedin_to_best_personal_email, /linkedin_to_personal_email, /linkedin_to_mobile_phone and /linkedin_to_business_profile. Costs run 1–4 credits per successful call. Designed for SaaS developers, GTM engineers and ad-tech platforms enriching their own identity graphs. Shares the api.rb2b.com host, account and credit balance with the Identification API.
