Word Tools API — Direct JSON Access

The Word Tools API exposes the same search engine that drives our free widgets as a raw JSON endpoint. You can call it from any language or platform and receive structured results without any widget markup.

Features

• Ten search types: Anagram, Scrabble‑scored, Words With Friends, Literati, Lexulous, Jumble, Crossword pattern, Pangram, Word check, and Reverse dictionary lookup.
• Sixteen dictionaries covering ten languages (English US/UK, Spanish, French, German, Italian, Dutch, Portuguese, Swedish, Norwegian, Danish) plus specialty word lists.
• Typical latency under 50 ms for a single request on our production servers.
• Responses are pure JSON; no HTML, no attribution required on paid plans.

Pricing

Metered plans are charged per 10 000 API calls. A free evaluation tier provides 100 000 calls per month for testing and development. Paid plans include white‑label rights, meaning you can embed the API in your product without displaying any PuzzleCast branding.

Status

The API program is currently in LAUNCH‑NOTIFY mode. We are finishing a production load‑proving phase for the underlying engine. Early access pricing will be offered to those who reserve a spot before the general release.

To request early access, email [email protected] with the subject line “API early access”. Include your intended use case and estimated monthly volume; we will confirm your early-access reservation and send pricing and credentials when the program opens.

Example Request / Response

GET request for anagrams of the letters “crane” using the American English dictionary:

GET /api/v3/search?SearchType=Anagram&Letters=crane&Dict=american&format=json

Successful response (pretty‑printed for readability):

{
  "count": 5,
  "results": [
    { "w": "crane", "l": 5, "s": ["c","r","a","n","e"] },
    { "w": "acern", "l": 5, "s": ["a","c","e","n","r"] },
    { "w": "cenar", "l": 5, "s": ["c","e","n","a","r"] },
    { "w": "nearc", "l": 5, "s": ["n","e","a","r","c"] },
    { "w": "racen", "l": 5, "s": ["r","a","c","e","n"] }
  ]
}

The count field indicates the total number of matches. Each result object returns the word (w), its length (l), and an array of sorted letters (s) for convenience.

Integration Notes

• All endpoints use HTTPS; API keys are passed via the Authorization: Bearer <token> header.
• Rate limits align with your purchased call volume; excess calls return HTTP 429.
