Prosper AI

Prosper AI is an AI-native voice automation platform for healthcare operations, founded in 2023 and backed by Andreessen Horowitz (a16z), Emergence Capital, Base10, Company Ventures and Y Combinator. Prosper runs the voice-heavy work of clinic and revenue-cycle operations end-to-end: answering and placing patient phone calls, appointment scheduling directly into the EHR, insurance eligibility and benefits verification, prior authorization, and patient billing follow-up. The platform integrates with 80+ EHR, practice-management and clearinghouse systems (Epic, athenahealth, Cerner, MEDITECH, NextGen, Nextech, Allscripts/Altera, Availity, Healthie). Prosper exposes a public REST API (Prosper Voice, /api/v1) for driving campaigns, targets, live calls and call-log export, plus a hosted, OAuth-protected Model Context Protocol (MCP) server for agent access. Prosper is HIPAA compliant and SOC 2 Type II attested and signs Business Associate Agreements.

Prosper AI publishes 6 APIs on the APIs.io network, including API Keys API, Call Logs API, Campaigns API, and 3 more. Tagged areas include Company, Healthcare, Voice AI, Revenue Cycle Management, and Patient Access.

Prosper AI’s developer surface includes documentation, API reference, getting-started guide, authentication, signup flow, engineering blog, and 13 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
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.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
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/prosper-ai: open an issue to ask a question, or submit a pull request to add artifacts.
