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-level bigrams (consecutive two-word token pairs) derived from the input text, suitable for downstream NLP tasks such as feature engineering, search indexing, or co-occurrence analysis.
Example use cases
NLP feature engineering for classifier
“Take this product review — 'The battery life is excellent but the screen is dim' — and extract all word bigrams from it so I can feed them as features into my text classification model.”
Keyword co-occurrence analysis
“I have this 2,000-word article about climate change. Pull out every consecutive two-word pair from it so I can see which word combinations appear together most often.”
Search index bigram enrichment
“Here's a chunk of customer support ticket text — run it through the word bigram extractor so I can index the two-word phrases for better search recall in our support system.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/word-bigrams/t9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost, per-call word bigram extraction from raw text, especially within an autonomous agent pipeline that uses x402 micropayments on Base. Ideal for NLP feature engineering, search enrichment, or co-occurrence analysis on text up to 50,000 characters without committing to a heavy NLP library or managed NLP service.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Empty or whitespace-only text input returns empty bigram set
- Non-string input type causes schema validation error
- Payment failure via x402 on Base blocks the call
- Malformed JSON body returns HTTP 400
