JSON · API key auth

Simple by design

One request. Everything you need.

A single GET request returns the PA verdict, PA type, clinical criteria, submission target, turnaround times, confidence score, and source URL.

What's included

Built for production.

Edge-deployed

Runs on Vercel Edge — globally distributed, sub-200ms response times from anywhere in the US.

PA lookup + compare

Two endpoints. Single-state PA lookup and multi-state divergence comparison in one subscription.

Structured next steps

Every PA-required result includes clinical criteria, submission target, and turnaround times — ready to render in your UI.

Drug + service coverage

Query by drug class code or service category. Drug add-on covers 20 drug classes across all states.

Subscription-scoped

Your API key is automatically scoped to your subscribed states. Out-of-scope requests return a clean 403.

CMS-0057-F verified

Every rule is confidence-scored and source-linked. You get the data and where it came from.

How we stay current

Human-verified.
Always current.

Every rule is monitored, verified, and updated by our team before it reaches you. We read the sources — CMS bulletins, state Medicaid agency notices, payer policy updates — so your team never has to call to confirm.
