I Built a Currency API with 57 Years of Historical Data for $9/month

#api

When I needed exchange rates for a financial dashboard project, I expected to pay $200+/month for a professional API. Then I found UniRateAPI.

The Problem with Currency APIs

Most currency APIs are either:

  • Free but unreliable: Hitting rate limits constantly, going down at worst times
  • Expensive: $50-500/month for the privilege of knowing what 1 USD equals in Euros
  • Missing history: "Sure, here's today's rate" - great, what about last year? Or 10 years ago?

I needed historical exchange rate data for an accounting project. The big players wanted $200+ per month for historical access. That's not happening for a side project.

UniRateAPI: The Budget Option That Actually Works

I stumbled on UniRateAPI and it changed my thinking:

  • 593+ currencies (FIAT, crypto, precious metals)
  • 57 years of historical data (1967-present)
  • Free tier: 200 requests/day
  • Pro tier: $9/month - unlimited requests
  • Response time: <100ms
  • 99.9% uptime

For $9/month, I get everything I need. Historical data included.

Quick Integration Example

Here's how easy it is to use:

from unirateapi import UniRateAPI

api = UniRateAPI('your_api_key')

# Get current rates
rates = api.get_rates('USD')
print(rates['EUR'])  # 0.92

# Convert currencies
result = api.convert(100, 'USD', 'EUR')
print(result)  # 92.15

# Historical data - this is the good stuff
historical = api.get_historical('1999-12-31', 'USD', 'EUR')
print(historical)  # What was the euro worth in 1999?
Enter fullscreen mode Exit fullscreen mode

Node.js too:

const UniRateAPI = require('unirateapi');
const api = new UniRateAPI('your_api_key');

const rates = await api.getRates('USD');
const converted = await api.convert(100, 'USD', 'EUR');
const historical = await api.getHistorical('2020-01-01', 'EUR', 'GBP');
Enter fullscreen mode Exit fullscreen mode

What You Actually Get

  • 593 currencies including things like Bitcoin and weird FIAT nobody uses
  • 57 years of history - go nuts, query 1967
  • Real-time updates - rates refresh from reliable sources
  • Clean API - no weird authentication quirks, just an API key

When to Use It

  • Financial dashboards
  • Accounting software
  • E-commerce with multi-currency support
  • Crypto projects needing FIAT conversions
  • Any project that needs to know what money was worth in 1995

When NOT to Use It

  • Ultra-high-frequency trading (you need Bloomberg Terminal anyway)
  • Mission-critical banking systems (get a proper enterprise solution)

The $9/month Math

Do the math: $9/month = $108/year. For historical currency data going back to 1967. That's less than Netflix. Less than Spotify. For a working API with decent documentation.

If you're building something that needs currency data and you're not on an enterprise budget, just use it.
