Client Libraries

To get started with minimal code, most of our APIs are available through client libraries and clients:

run in postman button npm logo pypi logo nuget logo swagger logo

Response Types

The User Agent Generator API supports the following response content types:

application/json, application/xml, application/yaml

You can specify the response content type by setting the Accept header in your request. If you don't specify a content type, the API will default to application/json.

Authentication

The User Agent Generator API uses an API Key to authenticate requests. You can view and manage your API key by visiting your dashboard.

Your API keys carry many privileges. To keep them from being abused, please do not share the keys on client-side code or Github etc. Keep them very secure.

All requests made to the API must contain the header x-api-key in each of your requests. API requests without authentication will fail.

All API requests must also be made over secure HTTPS. Requests made over plain HTTP will fail.

Error Code Meaning
401 Your request was made with invalid credentials. This error also appears when you don't pass the x-api-key header in your request.

Rate Limits

	
{
    "status": "error",
    "data": null,
    "error": "tokens have been depleted",
    "code": 429
}
	
							

Each subscription has its own monthly token limit. Your token count is based on your subscription plan. If you reach your limits, don't worry. You can always upgrade or downgrade at any time. View Pricing

When you reach your limit, the service will stop responding and typically return an HTTP 429 response status code. The error will also contain a detailed JSON.

The User Agent Generator API uses the following error code:

Error Code Meaning
429 You have exceeded your rate limit and further requests will be denied until the next cycle.

Error Codes

For reference, the User Agent Generator API uses the following error codes:

Error Code Meaning
Code Message
200 The request was successful. The response will include the requested data.
400 The request was invalid. The response will include a message that explains the error.
401 The request was not authorized. Usually, this means that the API key is missing or invalid.
403 This means that the request was trying to access a resource that it does not have permission to access.
404 This means that the resource you are trying to access does not exist.
429 This means that you have reached the rate limit. The response will include a Retry-After header that indicates how many seconds you need to wait before making a new request.
500 This means that there was an error on the server side. We are alerted when this happens and we will work to fix it as soon as possible.
