To protect server resources and ensure the fast performance of the Dragon Metrics API, calls are limited both by rate and a credit system.

How Credits Are Deducted

All calls to the Dragon Metrics API require credits, which are expended at the rate of 1 credit per result returned.

A "result" is defined as one instance of the main item being requested, and corresponds to the number in the "start" and "limit" parameters. Items inside the main object are not counted separately, regardless of their number. This means that in the Keyword Ranking endpoint, one keyword and search engine combination always counts as 1 result, whether it has 0 ranking URLs or 10,000.

For example, a call to the Campaigns endpoint that returns 10 campaigns will cost 10 credits, a call to the Keyword Rankings endpoint that returns 50 keywords will cost 50 credits, and a call the Keywod Groups endpoint that specifies a single keyword_group_id will cost 1 credit.

Credit Replenishment

Each account is given a definited number of credits each month. On the 1st of each month, they are replenished back to the original number, regardless of the amount used during the month.

Insufficient Credits

If there are not enough remaining credits to complete a call, you will receive an HTTP 429 (Too Many Requests) error, with a Dragon Metrics error object 2 (Out of Credits). On the first of the next month, when credits are replenished, you may continue making calls to the API.

If you would like to change the number of credits in your account, please contact support@dragonmetrics.com.

Get Your Current Remaining Credits

The /credits endpoint is available to see how many credits are remaining in your account this month. No parameters are required, and only a single value is returned.
