How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the word bigrams extracted from the input text — typically a list of consecutive two-word pairs (e.g. ['the quick', 'quick brown', 'brown fox']) derived from the provided string.
Example use cases
NLP feature engineering for classifier
“Take this product review — 'The battery life is amazing but the screen is too dim' — and give me all the word bigrams so I can use them as features in my sentiment model.”
Keyword co-occurrence indexing
“I need to build a co-occurrence index for this article about climate change. Can you extract all consecutive two-word pairs from the text so I can see which words appear together most?”
Plagiarism or similarity detection prep
“Break this 500-word essay into word bigrams so I can compare it against other submissions for similarity scoring.”
