Example use cases
Keyword inventory from support transcripts
“I have a batch of customer support chat logs — can you pull out every unique word and tell me how frequently each one shows up across this transcript?”
Vocabulary analysis of a blog post
“Here's the full text of my latest blog post — can you extract all the unique words and their counts so I can see which terms I'm using most?”
Tag hint generation from user notes
“Take these user notes and give me a list of every distinct word with its frequency so I can figure out which words would make the best tags or search hints.”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/unique-wordsWhen to prefer
Choose this endpoint when you need a simple, deterministic word-count inventory from a text blob without depending on external NLP APIs, embeddings, or subscriptions. It is ideal for lightweight keyword extraction from notes, pages, or chat transcripts where you just need token frequencies, not semantic analysis or part-of-speech tagging.
Side effects
- Text exceeds 100,000 character limit — structured validation error returned (not billed)
- Empty or missing text field — structured validation error (not billed)
- Payment not included or malformed x402 header — payment required error before processing
