How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns an object containing the extracted word bigrams from the input text, likely as an array or map of consecutive two-word token pairs derived from the input string.
Example use cases
NLP feature engineering pipeline
“Take this product review text and extract all word bigrams from it so I can use them as features for my sentiment classifier: 'The battery life is excellent but the screen resolution is disappointing.'”
Keyword co-occurrence analysis
“I have a news article here — can you pull out every consecutive two-word pair from it so I can see which words tend to appear together? Here's the text: 'Global markets surged today as inflation fears eased and investor confidence returned to record highs.'”
Document similarity preprocessing
“Break this paragraph into word bigrams for me so I can compare it against other documents using bigram overlap: 'Machine learning models require large amounts of labeled training data to achieve high accuracy on complex tasks.'”
