Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/word-bigrams/t10?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.03/call) extraction of the most statistically prominent two-word phrases from a block of text without standing up your own NLP pipeline. Ideal for agents doing lightweight text analytics, content auditing, or phrase pattern detection on documents up to 50,000 characters. Prefer this over full NLP suites when you only need bigram frequency data and want pay-per-use pricing.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Empty or whitespace-only text input — returns empty or minimal bigram list
- Text too short to generate meaningful bigrams — sparse or trivial results
- Payment failure via x402 — 402 response requiring USDC payment on Base
- Malformed JSON input — 400 bad request error
