Product Brief

What this API gives you

Foreign exchange rates against Indonesian Rupiah (IDR) from Frankfurter/ECB. Data is refreshed automatically daily via cron. Available pairs: USD, EUR, SGD, GBP to IDR.

Coverage
2

ready-to-use endpoints in this product, with JSON responses and consistent error handling.

Access
API key

Can be tested on the free tier, then used in production through one API Indonesia key.

Sample resource
https://use.apiindonesia.id/api/v1/kurs/latest

Returns the latest exchange rate for a given currency pair.

When should you use it?

The Exchange Rate API fits apps that need foreign-currency conversion to Rupiah for price displays, cost estimates, invoices, or finance dashboards using daily rates.

Prices from USD, EUR, SGD, or GBP need to be shown in IDR.

The app needs to store the rate used when a transaction is created.

Teams do not need BI transaction rates, only a lightweight daily market reference.

For reports that must use Bank Indonesia rates, use the BI Rates product. This Exchange Rate API is better for estimates and product displays.

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 & cross-border e-commerce: auto-convert prices to Rupiah at checkout.
  • Personal finance apps: show current rates for travel or overseas-shopping budgeting.
  • Accounting & invoicing: convert foreign-currency transactions to Rupiah using daily rates.

Quick answers to common questions about getting started, the free tier, 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.
The free tier includes 1,000 successful requests per month with a rate limit of 10 requests per second, plus access to every API product. After that, you can upgrade to Pro or Business, or top up pay as you go credits from the dashboard.
Only successful requests consume credits. Failed requests, validation errors, or server-side issues never reduce your balance, 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 and 20 requests per second; Business at IDR 149,000 gives 250,000 credits and 60 requests per second. 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.
