New Currency Fluctuation on Open Exchange Rates

Description:Emit new event when a new significant change in a specified currency rate is detected.

Version:0.0.1

Open Exchange Rates Overview#

The Open Exchange Rates API provides real-time and historical exchange rates for currencies worldwide, which enables you to retrieve the latest currency data for any purpose like financial reporting, pricing products in multiple currencies, or converting currency for international transactions. In Pipedream, you can tap into this API to create workflows that automate currency-related tasks, enrich data with current exchange rates, and trigger actions based on currency fluctuations.

Pipedream Overview#

Pipedream is an API that allows you to build applications that can connect to
various data sources and processes them in real-time. You can use Pipedream to
create applications that can perform ETL (Extract, Transform, and Load) tasks,
as well as to create data-driven workflows.

Some examples of applications you can build using the Pipedream API include:

An application that can extract data from a database, transform it, and then
load it into another database.
An application that can monitor a data source for changes, and then trigger a
workflow in response to those changes.
An application that can poll an API for new data, and then process that data
in real-time.
