Sign in to Yandex from here. Opens your browser to approve access; the code returns automatically over a local redirect, so this usually finishes in one call. If the local port is unavailable it returns a URL to approve and you then call submit_code with the code Yandex shows. Run this once (the token lasts ~1 year); needed before the data tools if you are not signed in yet.

Complete a copy-paste sign-in started by login: pass the code Yandex showed you after you approved access.

Discovery tool. Lists the counters available to your token plus a curated catalog of common dimensions and metrics (Metrica has no enumeration API), attribution options and Logs API fields. Call this before run_report or logs_request to use real field names and to find a counterId. For a counter's own goals, segments, filters or grants, use describe_counter. Read-only.

Read a single counter's configuration — settings, goals, segments, filters, operations and access grants — choosing sections with include. The goals section returns the goal ids needed to build conversion metrics (ym:s:goalreaches / conversionRate) in run_report, so call this with include=["goals"] before any conversion question. To list the account's counters, use get_metadata. Read-only.

Query a Yandex Metrica table report (/stat/v1/data): one or more metrics grouped by dimensions over a date range, with optional filter and sort. Read-only. Use get_metadata first to discover valid metric/dimension ids and the account counters.

Compare two segments/periods (A vs B) for the same metrics and dimensions (/stat/v1/data/comparison). Returns per-metric values for A and B plus the absolute and percentage delta, computed server-side: delta = B − A (segment A is the baseline), delta_pct = (B − A) / A × 100. Defaults to last 7 days (B) vs the prior 7 days (A), so a positive delta means growth. Read-only.

Return one level of a hierarchical (tree) report (/stat/v1/data/drilldown). Each row has an "expandable" flag; pass parentId with the path of dimension keys to expand deeper. Requires dimensions. Read-only.

Return metrics split into a time series (/stat/v1/data/bytime): each metric comes back as an array of values, one per interval (day/week/month/…) over the date range. Use for trends and charts. Optionally group by dimensions (topKeys rows). Read-only.

Create a Yandex Metrica Logs API request for RAW, un-sampled rows (source="visits" sessions or "hits" events) over a date range. Checks feasibility, then queues preparation (takes minutes). Returns a request_id to poll with logs_status; then logs_download, then logs_clean. Discover field ids with get_metadata. Not read-only: preparing data consumes the counter storage quota.

Inspect a Logs API request by request_id (status, parts, size, next step), or omit request_id to list all of the counter's log requests and current storage-quota usage. Poll this after logs_request until status="processed". Read-only.

Download prepared log data for a request_id (must be status="processed"; check logs_status). Default mode "sample" returns up to maxRows parsed rows inline — cheap and bounded. Mode "file" streams the FULL export to a file and returns its path plus a small preview; the raw content (potentially millions of rows) is never loaded into context. Read-only.

Free the counter storage quota by cleaning a finished (processed) log request, or cancel one still being prepared. Dispatches by current status. Destructive: cleaned data must be requested again to download later.
