Built so it cannot quietly mislead you

Absence is never an answer

A drug missing from a formulary means not covered— a worse outcome than needing authorization, not a better one. We say so explicitly, and we never render a gap as “no prior authorization required”.

A payer is not one policy

Humana files dozens of formularies. When requirements differ across a payer’s plans we report varies with the split, instead of picking whichever plan sorts first.

Auditable to the byte

We publish the SHA-256 of the exact CMS file behind each answer, so a determination can be checked against the bytes CMS served on the day we read them.

Callable by your software, and by your agents

A REST API, an OpenAPI 3.1 document and a hosted MCP server — the same determination engine behind all three. No incumbent in prior authorization exposes an agent-callable endpoint.

There is a public sandbox key, so an agent that finds our docs mid-task can make a real, correct call immediately without a signup flow it cannot complete.
