Proton.ai

Proton.ai is an AI industry cloud platform built for B2B distributors, combining an AI-guided CRM, product information management, e-commerce recommendation engine, and order-capture automation on top of a distributor's existing ERP and e-commerce systems. Proton exposes a public REST API (documented via Postman at api.proton.ai) offering an AI-powered suite of endpoints for product recommendations (cart, reorder, similar items, bought-also-bought, recently viewed), behavioral tracking, and CRM operations across customers, contacts, opportunities and pipelines, quotes, leads, call notes, tasks, and tenant-defined custom fields. Authentication is a static API key supplied at onboarding and sent in the X-Api-Key header, with an X-Company tenant header scoping every request. Proton is backed by Battery Ventures and headquartered around a distribution-industry focus.

Proton.ai publishes 12 APIs on the APIs.io network, including Call Notes API, Contacts API, Custom Fields API, and 9 more. Tagged areas include Company, CRM, Sales, Distribution, and Artificial Intelligence.

Proton.ai’s developer surface includes authentication, documentation, API reference, support, engineering blog, signup flow, and 9 more developer resources.
