What it does
DataForSEO offers APIs for search results, keyword research, backlink analysis, website auditing and related marketing datasets. Developers and automation builders can combine selected endpoints into their own research or reporting workflows.
DataForSEO is a collection of APIs for people building SEO software or automated reports. Choose the dataset first: search results, keywords, backlinks and website audits have different endpoints and billing units.
Create an account, open API Access and use the API credentials shown there. The API password is separate from the website login password. Authentication uses a Basic Authorization header; credentials should not be placed in URL parameters.
For supported endpoints, Standard queues work for later collection, while Live returns the result in the response and costs more. Check the endpoint's task, row or page charges before estimating a large job. Result retention also varies by retrieval method and format.
Access is prepaid pay-as-you-go, with no recurring subscription and no expiry on deposited funds. A signup trial credit and sample-response sandbox help with evaluation; sandbox responses are not fresh production research. Account, API and endpoint spending limits can constrain daily use, and automatic balance funding is optional.
