# Convert dated invoices to EUR at ECB rates

**Use case:** 

Converts a small list of foreign-currency invoices into EUR at the official ECB reference rate of each invoice date. Weekend and holiday dates use the last published rate and are flagged with isFallbackDate. You get the rate, converted amount and ECB date used for each item.

## About this Actor

This example demonstrates how to use [ECB Exchange Rates API: Daily, Historical, Conversion](https://apify.com/actose/ecb-exchange-rates.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/actose/ecb-exchange-rates.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
