Free API key, instantly: 1,000 calls a day
There is nothing to buy. Anyone can get a free key in seconds, verified labs that need more get 10,000 calls a day by request, and the API stays open with no key at 100 calls a day. Every caller gets the same answers from the same engine.

Quotas reset at midnight UTC and every response shows how many calls you have left. There is no card to enter and no contract to sign.
How a free key is issued
- Enter your email address on /research. The key appears on the page straight away, with a copy button and a curl example. There is no review and no wait.
- 1,000 calls a day, 250 typings per call. One key per email address. We keep the address with the key and use it for service notices only.
- Need more? Verified labs get the Lab tier. That is 10,000 calls a day and 5,000 typings per call, also free. Email hello@hlaverify.com from your work address. We verify the organisation and email the Lab key.
The same for every caller
- Your requests are not stored. Verification requests are processed in memory and discarded.
- No AI in the loop. Every answer is computed from the official IPD-IMGT/HLA files.
- One engine, one release. Every response names the release it was computed against.
- Reproducible. Any answer can be recomputed from the release it names.
Questions
What if I run out of calls?
The call returns 429 until midnight UTC. Every response shows how many calls you have left. A verified lab can move from 1,000 to 10,000 a day; if that is not enough either, write to hello@hlaverify.com.
Can we run it inside our network?
Yes, under Enterprise terms, as a container. Contact us.
What about model evaluation work?
A free key covers running the API in an evaluation. Training environments and licensing are scoped per project. Contact us.
Is this a medical device?
No. It is a research and evaluation tool that supports your validated procedures. See Trust.
