How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing word bigrams extracted from the input text — consecutive two-word token pairs derived by sliding a window of size 2 across the tokenized words in the text.
Example use cases
NLP feature extraction for classifier
“I need to turn this product review into word bigram features for my sentiment classifier — here's the review: 'The battery life is amazing but the screen resolution is disappointing compared to competitors.'”
Keyword pair analysis for SEO
“Extract all consecutive word pairs from this blog post so I can see which two-word phrases appear most often and optimize for them: 'Content marketing drives traffic. Good content marketing builds authority and drives organic traffic.'”
Text similarity preprocessing pipeline
“Take this paragraph and break it into word bigrams so I can use them as features for a document similarity comparison: 'Machine learning models require large datasets for training and produce accurate predictions when properly tuned.'”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/word-bigrams/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need word-level bigram tokenization specifically — not character n-grams or skip-grams — and want a cheap, pay-per-call option without a subscription. Ideal for NLP preprocessing pipelines, feature engineering for text classifiers, or co-occurrence analysis tasks where you need consecutive two-word pairs from text up to 50K characters.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Empty or whitespace-only text input returns empty bigram set
- Payment failure via x402 protocol on Base blocks the call
- Malformed JSON request body returns error response
- Text with only one word produces no bigrams
