Free Indonesian data APIs: wilayah, prayer times, NIK
1 August 2026
Some things should not cost anything. These four endpoints are free, need no signup, and are rate-limited rather than billed.
Wilayah — official region data
Provinces, cities and districts from the Kepmendagri tables, with their official codes. Useful for address forms, dropdowns, and validating that a region someone typed actually exists.

Prayer times
Daily prayer times for any Indonesian coordinate. No key, no quota to apply for.
NIK format check
A NIK is not random: it encodes a region code, a date of birth and a gender. This endpoint checks those internal relationships — whether the number is structurally coherent.
It does not confirm the person exists. That requires Dukcapil access, which is a different thing entirely. What it catches is a typo, a transposed digit, or an obviously invented number, before you spend anything on a deeper check.
NPWP format check
The same idea for tax numbers: checksum and structure, not existence.
Why free
They are cheap for us to run, and they are the sort of thing that should not sit behind a sales call. If they are useful and you later need something that costs money — reading a document, matching a face — you already know whether our API is pleasant to work with.
No account is needed for any of them. Call and see.
GlianaAI is a pay-per-call AI API: 90+ models plus Indonesian identity tools, no signup.
