Whitepages controls access to the API and data via an API Key. The API key is the primary data authentication method for your account. Also your usage is recorded and reported via the API Key. You can request the API key here.
We strongly recommend using HTTPS where possible to prevent third parties from acquiring your API key while in use.
Possible error responses for Whitepages Pro API requests and what they mean:
|HTTP CODE||ERROR NAME||Likely Cause|
|400||InvalidParametersError||Parameter called incorrectly|
|400||InputFieldError||Incorrect parameter information, such as non-existent area code on a phone number|
|400||InputError||No parameters given|
|400||Internal Error||If there is an internal error while performing the checks|
|403||AuthError||API Key is not authorized for that request|
|403||QuotaExceededError||API Key has exceeded its quota|
|500||ServerUnavailable||Whitepages Pro API temporarily unavailable|
Pass Through Parameters
Developers can also pass custom parameters for tracking purposes. Typical scenarios we see customers use this feature for are:
- Know which department or specific customer of yours is making the queries
- Pass internal parameters, like OrderId, so that usage queries can later be tied to specific Whitepages Pro queries, allowing for easy review of historic decisioning.
We recommend using format like ‘__’ (double under score) or “customerName_parameterName” to future proof against parameters we might add. These parameters can be accessed as part of the JSON response for Identity Check and Lead Verify products. They can also be accessed via the usage reports available for your account here:

How many calls can I make per second?
By default, as you sign up for the free API key, queries per second (qps) is rate limited to 4. As you move to a paid subscription, it can be increased to as high as 256 qps if needed.
How fast is the API response time?
Response times are as low as 0.2 secs for certain APIs but actual response times are dependent on the APIs you query.
The free queries allotment is not sufficient. is it possible to run a larger data test?
Please contact us at APISupport@whitepages.com and we will be happy to run a bigger data test for you.
