## Tools

### Check Semrush account units balance

**Slug:** `SEMRUSH_ACCOUNT_UNITS_BALANCE`

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.

### Get ad copies

**Slug:** `SEMRUSH_ADS_COPIES`

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.

### Get anchor texts

**Slug:** `SEMRUSH_ANCHORS`

Use this action to get a CSV report of anchor texts for backlinks pointing to a specified, publicly accessible domain, root domain, or URL.

### Get authority score profile

**Slug:** `SEMRUSH_AUTHORITY_SCORE_PROFILE`

Retrieves the Authority Score (AS) profile for a specified target, showing the count of referring domains that link to the target for each AS value from 0 to 100.

### Get backlinks

**Slug:** `SEMRUSH_BACKLINKS`

Fetches backlinks for a specified domain or URL as a semicolon-delimited CSV string (parse with `sep=';'`); allows customization of columns, sorting, and filtering. Consumes Semrush API credits per request. Ensure `display_limit` surpasses `display_offset` when an offset is used, and note the `urlanchor` filter may have limitations for targets with extensive backlinks.

### Backlinks overview

**Slug:** `SEMRUSH_BACKLINKS_OVERVIEW`

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.

### Batch comparison

**Slug:** `SEMRUSH_BATCH_COMPARISON`

Compares backlink profiles for multiple specified targets (domains, subdomains, or URLs) to analyze and compare link-building efforts.

### Batch keyword overview

**Slug:** `SEMRUSH_BATCH_KEYWORD_OVERVIEW`

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.

### Broad match keyword

**Slug:** `SEMRUSH_BROAD_MATCH_KEYWORD`

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.

### Get categories

**Slug:** `SEMRUSH_CATEGORIES`

Retrieves categories and their 0-1 confidence ratings for a specified domain, subdomain, or URL, with results sorted by rating. Response is returned as semicolon-separated text in a single 'data' field requiring parsing before use. Some niche or atypical targets may return no category data.

### Get categories profile

**Slug:** `SEMRUSH_CATEGORIES_PROFILE`

### Get competitor data

**Slug:** `SEMRUSH_COMPETITORS`

### Get competitors in organic search

**Slug:** `SEMRUSH_COMPETITORS_IN_ORGANIC_SEARCH`

The literal response `ERROR 50 :: NOTHING FOUND` means zero results for that domain/database combination, not a system error. Traffic metrics (e.g., `Tr`) are modeled estimates incompatible with first-party analytics data.

### Get domain organic search keywords

**Slug:** `SEMRUSH_DOMAIN_ORGANIC_SEARCH_KEYWORDS`

Retrieves organic search keywords for a domain from a specified Semrush regional database; `display_positions` must be set if `display_daily=1` for daily updates.
