## Description

API for retrieving web traffic and online market intelligence data for competitor analysis.

## AI-native score: Unrated

Available here: [Task-completion verdicts](#jobs-to-be-done). Coverage measures research breadth across scored fields.

Research coverage is 12/100. An AI-native grade requires 40/100. The provisional breakdown below shows the AI-native signals recorded so far. The AI-native score measures agent-readiness and is not a substitute for your own security or vendor-risk review. See [methodology](/methodology/) for how coverage and the grade are computed.

## Jobs To Be Done

From cited vendor documentation, each completion verdict says whether an agent can deliver the job's main outcome by and large through this product and which steps still need a person. Scope may limit cases or prerequisites while preserving that outcome. An unknown verdict means the answer is not yet established.

- **Research website traffic** — Retrieve estimated website visit counts for a chosen domain and time period to support market or competitor research.
  - Route: API
  - Completion: Documented complete
  - Setup needs a human: Unknown
  - Per-task human step: Unknown
  - On behalf of a principal: Unknown
  - Scope: A Similarweb API customer retrieves estimated visit counts for a chosen website domain and date range through the total-traffic-and-engagement visits GET endpoint. The result combines desktop and mobile visits and supports market or competitor research for the selected country and granularity. Completion ends at retrieval of the traffic estimates.
  - Conditions: An active API key and subscription access are required. An account admin generates API keys. Historical access extends up to 37 months depending on subscription, and available country filters depend on account capabilities. Human setup and execution requirements and agent permission to act for a principal remain unassessed.
