EveryData platform API
SimilarWeb API
Similarweb domain metrics, competitor domains, and audience-overlap records are the SimilarWeb objects documented here; 3 actions including `search`, `competitors`, `audience` keep SimilarWeb selectors and outputs separate.
On SimilarWeb, `search` handles matching public results through `keyword`, while `competitors` handles competitor-domain records through `keyword`; neither SimilarWeb action receives undeclared filters.

What does each SimilarWeb action accept?
Each answer below pairs one callable action with its real inputs. Parameter meanings and allowed values are action-specific; a familiar name does not carry the same meaning across every platform.
Official sources are linked only to clarify the platform term beside them. They do not imply platform authorization or endorsement, and they do not add official-site features to the EveryInfra API contract.

SimilarWeb API questions
What can I retrieve with the SimilarWeb API?
Set platform to similarweb. The current catalog lists search, competitors, and audience. These action names identify different SimilarWeb objects or views; they are not interchangeable search modes.
Which input starts a SimilarWeb `search` request?
Specifies the target domain to analyze (such as example.com) rather than a general search keyword query. Depending on the action selected, this parameter retrieves traffic overviews for search, lists similar sites for competitors, or extracts domain visitor profiles for audience. Returned metrics are third-party estimations and do not reflect internal GA4 analytics measurements. Send it as keyword inside params.
Which fields can SimilarWeb `search` return?
Its declared schema includes name, text, category, and global_rank. A declared field can still be absent from an individual source record, and every other action has its own field list.
Does every SimilarWeb action return immediately?
No assumption is needed: this page labels each action's delivery mode. The current catalog contains sync delivery; poll a returned job ID only for an action labeled asynchronous.
