How we review

Extended accessThe tool runs code or makes network calls and only reads external data.

  • Starts a server via uvx that reads Wordstat statistics with a Yandex Cloud key
  • Requests are paid, the server keeps a local log and estimates cost in advance

This is third-party code. Review the repository files before installing.

What it does

A thin wrapper over the Wordstat methods of the Yandex Search API: top queries with related phrases, frequency dynamics by month/week/day, regional distribution with an affinity index, and the region code tree. Separately from Wordstat itself, the server keeps a local call log and offers two cost-tracking tools: wordstat_cost_report for a summary of actual spend, and wordstat_cost_estimate to price a batch of requests before the agent sends them.

Who it is for. For anyone who wants visibility into paid Search API spend both before and after an agent makes requests.

Good fit when

  • You need Wordstat frequency and dynamics with transparent cost tracking
  • You want to price a batch of requests before a large keyword-collection run
  • You want a one-line uvx install straight from GitHub, no cloning

Not a fit when

  • You have no card attached to Yandex Cloud billing: without it the Search API often returns 403
  • You need tools beyond the four Wordstat API methods

Example request

Estimate how much it would cost to check yearly dynamics for 50 phrases before running it

Limitations

FAQ

Why does the Search API return 403?

Usually there's no card attached to Yandex Cloud billing, or the key has the wrong scope, the README covers both cases.

How do I see how much I've already spent?

The wordstat_cost_report tool summarizes spend from the local call log.
