Data Request from Power BI Power Query

Question

I have created a custom function in Power BI's Power Query that asks for Longitutde and Latitude for addresses within a dataset. It makes the request of the Bing API. What is the maximum amount of records one can do this for in the Dev account?

@Steve Smith Thanks for reaching out to us, may I get some clarification on which Bing API you are mentioning? Is that Bing Map API since you mentioned address, Longitude and Latitude?

In the Bing Maps terms of use trial and basic keys are limited in the number of transactions they can generate within a period of time. Public facing Windows Store, Windows Phone, and WPF apps have a limit of 50,000 transactions in a 24 hour period. Internal Windows apps, public facing web sites and non-Windows mobile apps have a limit of 125,000 transactions a year. Rate limiting occurs when the frequency of requests made against the Bing Maps REST and/or SOAP services by an account exceeds these free terms of use. Rate limiting can also occur when the services are under a lot of load. This is done to ensure that the usage from trial and basic keys do no interrupt the services for those using an Enterprise keys. Enterprise keys are not rate limited and the only way to get around rate limiting is to upgrade to an Enterprise key. For more information see our Bing Maps Licensing Options page.

When a request is rate limited, the response will return no results. This may be confusing at first as it looks like Bing Maps was unable to find results. To indicate that the request was rate limited a flag is added to the header of the response (X-MS-BM-WS-INFO) which is set to the value of 1 as documented the Status Codes and Error Handling page. To make for a better user experience, applications that use trial or basic keys should look for this flag in the header and handle requests which are rate limited. Something as simple as logging the fact that a request was rate limited in your application log could help when debugging reported issues.

I hope this helps.
