How health is measured

Health = the share of calls that returned data, in percent. Empty results, failures and unknown outcomes do not count as returning data.
Levels: 90% and above is healthy, 70% and above is available, 40% and above is limited; anything lower is mostly down.
A period (the last 24 hours, one hour or one day) gets a score only once it has at least 50 calls. Periods with fewer calls show as normal: a few failures among a handful of calls do not mean the API is down.
Calls include real customer calls and our own daily probe calls. Request errors (wrong parameters, no balance) are excluded.
Average time counts only calls that completed normally: response time for sync calls, acceptance to completion for async ones.

Search public results on SimilarWeb. Accepts these parameters: keyword. Returns these fields: top_keywords, name, avg_visit_duration, and global_rank.

Price $1.39 per 1,000 requests ($0.001389 per call). Failed calls and empty results are not charged. Synchronous. For slow jobs add "mode": "async" to the body, take the job_id and poll.

Request parameters

Name	In	Type	Required	Default	Description
`Authorization`	header	`string`	Yes	-	Bearer followed by your API key. Create it in the console; never put it in a URL or a code repository.
`platform`	body	`string`	Yes	`similarweb`	Platform identifier, fixed value.
`action`	body	`string`	Yes	`search`	Capability identifier, fixed value.
`keyword`	body.params	Not declared	Yes	-	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.
`limit`	body.params	`integer (1–)`	No	-

Response example

Real response

Captured September 26, 2026 at 08:56 (UTC) by calling this API with the parameters in the code sample above. results and count are that call's real response with personal information (names, handles, avatars, profile links, contact details) removed. id, billing and quota differ on every call, so only their shape is shown.

`category`	Category name in the source platform's own taxonomy, not normalized across platforms.
`global_rank`	Keeps the platform's own meaning
`country_rank`	Keeps the platform's own meaning
`category_rank`	Keeps the platform's own meaning
`country`	Country or region: a full name or an ISO code depending on the platform, not normalized.
`monthly_visits`	Keeps the platform's own meaning
`bounce_rate`	Keeps the platform's own meaning

Errors and billing

401: Missing or invalid key. Authentication runs before parameter checks, so unauthenticated requests never see the parameter schema.
422: Wrong parameter name or value. The error lists the parameters and allowed values this capability accepts and the closest match; it happens before any charge.
402: Insufficient balance. Top up first.
429: Per-minute request limit reached. Wait for Retry-After and try again.
503: Could not complete right now. Any charge for the call goes back to your balance automatically, and the billing receipt in the response states the actual outcome, including when it is not yet known. Do not resend blindly.
200 empty: The request completed without data and is not charged (billing.reason = empty_result_refunded).

Official references
