Example Use Cases
These are the Semrush actions Snow can use when building apps with you. Connecting an account does not make Snow run these on its own.
Tool to fetch the remaining Semrush Standard API units for the authenticated account. Use this before launching large batches of Semrush report requests to preflight and fail fast if units are exhausted or below a required threshold.
Determines the Keyword Difficulty (KD) score (0-100, higher means greater difficulty) for a given phrase in a specific Semrush regional database to assess its SEO competitiveness. Returns CSV-formatted text; parse before programmatic use.
Provides a semicolon-delimited (sep=';') CSV summary of backlinks, including Authority Score and link type breakdowns, for a specified and publicly accessible domain, root domain, or URL. A result of 'ERROR 50 :: NOTHING FOUND' means the target has no data in the database and is a valid zero-result response.
Compares backlink profiles for multiple specified targets (domains, subdomains, or URLs) to analyze and compare link-building efforts.
Fetches a keyword overview report from a Semrush regional database for up to 100 keywords, providing metrics like search volume, CPC, and keyword difficulty. Response is CSV-like text (not JSON); parse accordingly. Returns literal string 'ERROR 50 :: NOTHING FOUND' for keywords with no data in the selected database — treat as zero results and fall back to SEMRUSH_KEYWORD_OVERVIEW_ONE_DATABASE or SEMRUSH_KEYWORD_OVERVIEW_ALL_DATABASES for those terms.
Fetches broad match keywords for a given phrase. Response is CSV-like text (not JSON); parse by splitting on line breaks and delimiters. `display_sort` and `display_filter` parameters are defined but currently not utilized by the API call.
Analyzes keyword rankings by comparing up to five domains to find common, unique, or gap keywords, using specified organic/paid types and comparison logic in the `domains` string.
Call this to find related keywords (including synonyms and variations) for a target phrase in a specific regional database; `display_date` (if used for historical data) must be 'YYYYMM15' for a past month. Response is CSV-like delimited text (not JSON); parse by splitting on newlines and delimiters to extract structured rows.
Retrieves unique ad copies Semrush has observed for a specified domain from a regional database, detailing ads seen in Google's paid search results. Results are a sampled subset, not a complete picture of the domain's advertising. Response is returned as a CSV-like string; parse columns (e.g., Tt, Ds) using the pipe or semicolon delimiter.
Use this action to get a CSV report of anchor texts for backlinks pointing to a specified, publicly accessible domain, root domain, or URL.
