Datamuse Word Finder Scraper

Datamuse Word Finder Scraper

Scrape related words, rhymes, synonyms, and more from the Datamuse API, up to a million per run. Every word comes with its score, part-of-speech tags, and optional dictionary definitions. No API key required. Export to CSV, JSON, Excel, or XML.

Finding the right word is hard when a thesaurus gives you stale, unrelated suggestions. The Datamuse API is a word-finding engine that understands phonetic similarity, semantic meaning, and contextual usage, but querying it by hand for large lists is slow and repetitive. This Actor automates the entire process, letting you feed in a seed word and collect a structured dataset of related terms in seconds.

Who uses it	What they scrape Datamuse for
Copywriters and content marketers	Generating a bank of semantically related keywords and phrases for a new campaign.
SEO specialists	Building long-tail keyword lists from a seed topic to find low-competition search terms.
Linguists and NLP engineers	Collecting structured lexical data like hypernyms, meronyms, and trigger words for language model training.
Poets and songwriters	Finding perfect and near rhymes with syllable counts and frequency data.

What it does

This Actor collects word suggestions from the Datamuse API by relationship type and returns each one as a flat row with its score, tags, and optional definition.

• 🔗 18 relationship types: means like, sounds like, rhymes, synonyms, antonyms, hypernyms, hyponyms, holonyms, meronyms, triggers, and more.
• 📖 Optional definitions: append dictionary definitions to every word in the result set.
• 🏷️ Part-of-speech tags: include tags for grammatical category, syllable count, word frequency, and pronunciation.
• 🎯 Contextual filters: bias results by topic, or require a specific word to appear immediately before or after the target.
• 🗂️ Part-of-speech restriction: limit results to nouns, verbs, adjectives, or adverbs only.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

What you can do with Datamuse data

📝 Generate a keyword universe for a blog post.

A content strategist enters a seed topic like 'productivity' with the 'means like' query and collects 500 semantically related terms to build a content brief.

🎤 Find multi-syllable near rhymes for a lyric.

A songwriter uses the 'near rhymes' query with a seed word, filters by syllable count via the tags, and exports a CSV of usable slant rhymes.

🧠 Build a lexical knowledge graph for an NLP model.

An NLP researcher runs the Actor repeatedly with 'hypernyms' and 'holonyms' queries to collect hierarchical word relationships for a custom taxonomy.

🔎 Solve a crossword or word puzzle with wildcards.

A puzzle enthusiast uses the 'spelled like' query with a pattern like 'c?t*' to get every matching word, complete with definitions to verify the clue.

Configure the run

Drive the Actor with a single seed word or wildcard pattern, then narrow results by topic, left/right context, and part of speech before they reach your dataset. The Input tab lists every parameter.

A first run with the defaults:

{
  "maxItems": 10,
  "queryType": "means_like",
  "seedWord": "happy"
}

A larger pull:

{
  "maxItems": 200,
  "queryType": "means_like",
  "seedWord": "happy"
}

Troubleshooting

Why am I getting no results?

Check that your seed word is spelled correctly and is a real English word. For wildcard queries with 'spelled like', verify your pattern uses '?' and '*' correctly. Also try removing optional filters like topic, context, or part of speech to broaden the search.

Why are the definitions missing for some words?

The Datamuse API does not have definitions for every word in its database. If a word lacks a definition, the 'defs' field will be empty. This is expected behavior for less common or newly added terms.

Why did I get fewer results than my maxItems setting?

The Datamuse API returns only the words that exist in its database for your query. If there are only 47 near rhymes for 'orange', setting maxItems to 100 will still return only 47 results. The Actor stops when the API has no more words to return.

Why are the part-of-speech tags showing 'Unknown'?

Not all words in the Datamuse database have complete tag information. If a tag value is unavailable, it may appear as an empty string or be omitted. This is more common for rare or specialized vocabulary.

The Actor is running slowly for a large maxItems value.

The Datamuse API has a maximum page size of 100 words per request. Collecting 10,000 words requires 100 sequential API calls. There is no way to speed this up as it is a limitation of the underlying free API.

FAQ

Question	Answer
Do I need a Datamuse API key?	No. The Datamuse API is free and public. This Actor makes requests directly to the public endpoint with no authentication required.
What is the difference between 'means like' and 'synonyms'?	'Means like' returns words that are semantically related, including near-synonyms and contextually similar terms. 'Synonyms' returns strict synonym pairs from the WordNet database.
How do I find words that start with a specific letter pattern?	Use the 'spelled like' query type and enter a wildcard pattern. Use '?' for a single unknown character and '' for any number of characters. For example, 'th' returns all words starting with 'th'.
Can I get definitions for the returned words?	Yes. Enable the 'Include definitions' checkbox in the input. Each word in the result will have a 'defs' field with dictionary definitions when available.
What do the part-of-speech tags look like?	When 'Include part-of-speech tags' is enabled, each word gets a 'tags' field containing up to four values: the grammatical part of speech (e.g., 'n' for noun), the number of syllables, the word frequency rank, and a pronunciation string.
How do I bias results toward a specific topic?	Fill in the optional 'Topic Word' field. The Datamuse API will favor words that are contextually related to that topic when returning results.
Can I find words that typically appear before or after another word?	Yes. Use the 'Left Context' field to specify a word that immediately precedes the target, or 'Right Context' for a word that follows it. These map to the Datamuse 'lc' and 'rc' parameters.
What is a hypernym or hyponym?	A hypernym is a broader category word (e.g., 'animal' is a hypernym of 'dog'). A hyponym is a more specific word (e.g., 'poodle' is a hyponym of 'dog'). Use these query types to build taxonomies.
How many words can I collect in one run?	You can set the 'Maximum words' field up to 1,000,000. The actual number returned depends on how many matching words exist in the Datamuse database for your query.
What is the 'score' field on each word?	The score is a normalized value between 0 and 100 that indicates how strongly the word matches your query. Higher scores mean a closer match.
