## What it is
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
