SuperDial

SuperDial builds voice AI agents that automate high-friction administrative phone calls in healthcare revenue cycle management. Its agents place outbound calls from providers, billing teams and RCM companies to insurance payers — navigating IVR phone trees, holding, and conducting live conversations with payer representatives — and return structured, auditable results. Common workflows include benefits verification, prior authorization, claim status, provider data validation, and credentialing and enrollment outreach. The SuperDial API exposes this as an asynchronous job API: a client submits a "request" against an account-provisioned schema, SuperDial fulfills it across digital and phone modalities, and delivers the structured result by signed webhook or polling. Founded in 2021 in San Francisco as SuperBill by Stanford classmates Sam Schwager and Harrison Caruthers, the company raised a $15M Series A led by SignalFire in 2025.

SuperDial publishes 1 API on the APIs.io network. Tagged areas include Company, Healthcare, Revenue Cycle Management, Voice AI, and Insurance.

The SuperDial catalog on APIs.io includes 1 event-driven AsyncAPI specification.

SuperDial’s developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, authentication, sandbox, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Insurance 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.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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/. This rating is computed from github.com/api-evangelist/superdial: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
