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 13 APIs on the APIs.io network, including Call Notes API, Contacts API, Custom Fields API, and 10 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 10 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/protonai: open an issue to ask a question, or submit a pull request to add artifacts.
