Returns bank codes with valid account number lengths.

When should you use it?

The Validation API fits cleaning inputs before data enters your system: NIK, NPWP, phone numbers, and bank accounts. It focuses on structural validation, not identity checks against official databases.

Onboarding forms often fail because NIK, NPWP, phone, or bank-account formats are inconsistent.

The app wants to give immediate feedback before submission.

Teams need to reduce dirty data before KYC, billing, or disbursement workflows.

Structural validation does not prove that a number belongs to someone or is active at the related institution.

Example product scenarios

This section separates the product page from the docs. The docs explain how to call endpoints; this page explains why the endpoints make sense for your feature.

  • Fintech & e-commerce: validate NIK/NPWP/bank-account format on signup forms before submission.
  • HR-tech: check NIK/NPWP format validity during employee onboarding.
  • Form-builder apps: reduce identity/tax data entry errors in real time.

Quick answers to common questions about getting started, the signup bonus, API key security, data sources, and Sumopod billing.

API Indonesia is a REST API service for Indonesian public data: administrative regions down to village and postal code level, public holidays, prayer times, schools, universities, hospitals, and realtime earthquake data from BMKG — all through a single API key.
Fully self-service: sign up, create an API key in the dashboard, and start calling endpoints with the x-api-key header. No manual verification, no sales calls — you can make your first request within minutes.
Yes. API keys are stored as SHA-256 hashes so they are never persisted in their original form, and all traffic runs exclusively over HTTPS. If a key is ever exposed, you can rotate or revoke it at any time straight from the dashboard.
Every new account gets a one-time 3,000 credit bonus (Rp3,000), granted once the email is verified. With Google or GitHub signup it lands right away, because the provider already verified the email. There is no monthly free allowance on any plan tier, and the bonus never expires. Once the balance runs out, you can upgrade to Pro or Business or top up pay as you go credits from the dashboard.
One credit equals Rp1, and the price is per product per hit: a successful public data request costs 2 credits (Rp2). Only successful hits consume a balance: failed requests, validation errors, and timeouts are never charged, so you only pay for data you actually receive.
Upgrade straight from the dashboard with payment through Sumopod. Pro at IDR 49,000 gives 50,000 credits (Rp50,000, equal to 25,000 public data requests) and 20 requests per second; Business at IDR 149,000 gives 250,000 credits (Rp250,000, equal to 125,000 requests) and 60 requests per second. One credit equals Rp1 and a successful public data request costs 2 credits. If you do not want a subscription, you can also buy pay as you go credits. Yearly billing saves 2 months.
All data comes from official sources: Permendagri for regions, SK Menpan for public holidays, Kemenag for prayer times, Dapodik Kemdikbud and Dikti for education, SIRS Kemenkes for hospitals, and BMKG for earthquakes (required attribution: "Data sourced from BMKG"). Data is refreshed as the official sources publish updates; earthquake data is available in realtime.
Yes. API Indonesia runs on Cloudflare's edge network with 99.9% uptime and sub-100ms response latency. This distributed infrastructure keeps the API fast and reliable for production workloads — from fintech KYC to high-traffic e-commerce checkouts.
