Frequently asked questions

Ceven stores your Fixer.io API key in an encrypted vault that is isolated from the model training process. When a workflow requires a currency conversion or a historical rate lookup, the agent retrieves the key at the moment of the request to authenticate with the Fixer.io servers. We never share this key with third party plugins or store it in plain text. You can rotate your key within your Fixer.io dashboard and update it in the Ceven integration settings instantly to ensure your account remains secure and access is strictly controlled by your own administrative preferences.
The number of currencies you can convert depends on the specific Fixer.io plan you have active. While the API supports a vast array of global symbols, some lower tier plans may restrict the base currency to EUR or limit the frequency of updates. Ceven handles these restrictions by checking the API response codes. If a request is denied due to a plan limitation, the agent will notify you exactly which restriction was hit, such as an attempt to change the base currency on a free plan, so you can upgrade your subscription if needed.
Yes, Ceven can access historical data provided by Fixer.io dating back to the start of their records. You simply provide the specific date in the workflow prompt, and the agent calls the historical rates endpoint. This is particularly useful for year over year financial audits or analyzing long term currency trends for legacy contracts. The agent can iterate through multiple dates to build a custom dataset, though it will respect the rate limits of your API plan to avoid being throttled during large data extraction tasks.
The update frequency is determined by your Fixer.io plan level. Free plans typically have a slower update cadence, while professional and enterprise plans offer real time or hourly updates. Ceven always pulls the most recent data available to your account. If your plan provides updates every sixty seconds, the agent will reflect that precision. You can configure your Ceven workflows to trigger based on these updates, such as updating a price list every time the Fixer.io latest rates endpoint refreshes its data.
Ceven implements a retry logic with exponential backoff for all Fixer.io calls. If the API returns a server error or a timeout, the agent will wait a few seconds before trying again. If the service remains unavailable after several attempts, the workflow will pause and send a notification to the administrator. This prevents the system from pushing incorrect or zero value rates into your accounting software, ensuring that your financial records remain accurate and that no broken data enters your production environment.
Yes, the Fixer.io time series endpoint has a strict limit where you can only request data for a maximum of 365 days in a single call. If you need a window longer than one year, Ceven automatically splits the request into multiple smaller chunks. The agent will fetch the data in yearly segments and then merge the results into a single continuous timeline for your report. This happens in the background, so you only see the final combined dataset without having to manually manage the date ranges yourself.
Fixer.io provides current and historical data, not predictive forecasting. Ceven uses this data to report what is happening now or what happened in the past. While the agent cannot predict future rates, it can analyze historical volatility using the fluctuations and time series tools to help you identify patterns. You can build a workflow that calculates the average monthly move for a currency pair over the last year to help inform your own hedging strategy, but the data itself is strictly factual and retrospective.
Ceven processes the raw floating point numbers returned by the Fixer.io API to maintain maximum precision during intermediate calculations. You can specify the desired decimal precision in your workflow settings, such as rounding to two decimal places for consumer pricing or four decimal places for institutional forex trading. The agent applies this rounding only at the final step before pushing the data to your destination system, which prevents the accumulation of rounding errors that often occurs when multiple conversions are chained together in a single process.
