A self-hostable REST API service that serves current and historical foreign exchange rates published by the European Central Bank, built on Python's Sanic async framework with PostgreSQL via GINO/asyncpg. An hourly scheduler keeps the database updated with the latest ECB reference rates, and the hosted version at exchangeratesapi.io is now a commercial APILayer product.

Use cases

• get latest and historical currency exchange rates via a REST API
• self-host a free exchange rates API backed by ECB data
• convert currencies client-side with money.js using fetched rates
• query historical forex rates for a date range
• power a finance dashboard with daily ECB reference rates

When to choose

• you want a free, self-hosted exchange rate API based on ECB daily reference rates
• you need historical rates back to 1999 without paying for a commercial forex API
• you need high-throughput async serving of currency rates

When to avoid

• you need real-time intraday rates updated every minute - ECB data updates once per working day
• you need currencies beyond the ECB reference set or precious metals
• you want a maintained turnkey service - the hosted product is now commercial and the repo's last release was 2022
