What's included
Runs on Vercel Edge — globally distributed, sub-200ms response times from anywhere in the US.
Two endpoints. Single-state PA lookup and multi-state divergence comparison in one subscription.
Every PA-required result includes clinical criteria, submission target, and turnaround times — ready to render in your UI.
Query by drug class code or service category. Drug add-on covers 20 drug classes across all states.
Your API key is automatically scoped to your subscribed states. Out-of-scope requests return a clean 403.
Every rule is confidence-scored and source-linked. You get the data and where it came from.
How we stay 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.
