How it works
The mechanics, plainly
Fetch any dataset URL from /data/ and you get JSON or CSV. There is no authentication step and no quota to request. Reuse, including commercial reuse and redistribution, is permitted provided Harpd is attributed and the data date is kept with the figure.
How it compares
Harpd vs the traditional approach
| Aspect | Harpd / this model | Traditional |
|---|---|---|
| Cost | Free for public datasets | Often subscription-gated |
| Access | No key, no signup | Account required |
| Reuse | CC BY 4.0, commercial allowed | Restricted or negotiated |
| What is paid | Only promotional Rank Points, disclosed | Often the data itself |
Why it matters
Free open data is what makes a platform citable. If a figure sits behind a login it cannot be checked by a reader, which means it cannot be responsibly quoted. Harpd's paid product is promotion, not access — and that is stated plainly.
Frequently asked questions
Is there a paid tier of the data?
No. Public datasets are free. Harpd's paid product is promotional placement on Harpd Rank, which is disclosed on every board and has nothing to do with data access.
Do I need to register to use the API?
No. The public endpoints are keyless and read-only. Registration exists only for makers managing their own listings.
Can I resell Harpd data?
CC BY 4.0 permits redistribution, including commercially, with attribution. Keep the data date with any figure you redistribute.
