How this service works
Find words matching a crossword or Wordle pattern: t??k finds task, trek; ? is one letter, * any letters.
Output
Returns a list of matching words sorted by frequency score, each with a word string, a relevance/frequency score, and a frequency-per-million value. Also includes the matched pattern, total count of results, data source attribution, and optional summary or disclaimer fields.
Example use cases
Crossword puzzle letter fill-in
“I'm doing a crossword and I need a word that fits the pattern ?r??zy — it's 6 letters, starts with something, then r, then two unknowns, then z, y. What words match that?”
Wordle solver with known positions
“In my Wordle game I know the word has a 'c' as the first letter and an 'e' as the last letter, and it's 5 letters total — find me words matching the pattern c???e.”
Word game brainstorming for a prefix and suffix
“I need words that start with 'pre' and end in 'tion' for a word puzzle — can you find words matching pre*tion and give me up to 30 results?”

Endpoint
GEThttps://word-tools.x402tookit.com/word-pattern?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to find real English words that conform to a specific positional letter pattern, such as crossword or Wordle solving. Prefer this over a reverse dictionary or completion endpoint when you have fixed letter positions and unknown gaps, rather than a known prefix or a meaning-based query.
Side effects
- Invalid pattern syntax (missing letters or unsupported characters) returns no results or an error
- Pattern that matches no words returns an empty results array with count 0
- Limit parameter out of range (below 1 or above 50) may be clamped or rejected
- Very broad patterns like * alone may return too many matches or be rejected
- Service degradation flag may be set if the word database is partially unavailable
