HANK CODES API
HANK CODES is a healthcare API platform. One API key works across every service,
through a single edge at https://api.hank.ai/v1/.
- One key, every service your plan includes. Create a key once at
API Keys; use it for codesets, claim-cleaner, scholar, and
anything we add later that your plan entitles you to. (A call to a service your
plan doesn't include returns
403. See Authentication.) - One base URL. Every service lives under
https://api.hank.ai/v1/<service>/. - One credit model. Each operation costs credits; usage shows as a percentage on your dashboard. See Credits & pricing.

Data handling, BAA & zero data retention
If you send Protected Health Information (PHI), sign a Business Associate Agreement first (Account → Business Associate Agreement). A BAA permits PHI and binds us to HIPAA safeguards; without one, send synthetic / non-patient data only.
Separately, BAA-covered organizations can turn on zero data retention (ZDR) per service in Account → Data retention. For those services we process your request and keep nothing afterward. ZDR is available on services that don't need to retain your input (Safe Harbor, Codesets, Claim Cleaner, PPM, ARSE, KRAC); it is not available on Scholar, whose chat requires conversation history. See the Privacy Policy §8.1 for details.
