How this service works
Deterministic text segmentation utility: Return last words; parameter=2. Tier 7/10 provides progressively richer diagnostics.
Output
Returns the last 2 words extracted from the input text, along with tier-7 progressive diagnostics that include richer segmentation metadata such as character offsets, word boundaries, and processing details about the extraction.
Example use cases
Extract trailing words from log entries
“I have a bunch of log lines like 'ERROR 2024-01-15 connection timeout' — can you pull the last 2 words from each one deterministically so I can categorize the error types?”
Parse last words of user-generated captions
“Take this caption — 'Beautiful sunset over the Golden Gate Bridge' — and give me just the last 2 words, with the full diagnostic breakdown.”
Tail-word extraction for NLP pipeline
“For my preprocessing step, I need to extract the last 2 words from the sentence 'Machine learning models require careful tuning' — use the deterministic segmentation utility and show me the tier-7 diagnostics.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v11/text-segment/tail-words/p2/t7?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, deterministic, pay-per-call utility to reliably extract the last 2 words from a text string and want richer tier-7 diagnostic metadata alongside the result. Ideal for autonomous agent pipelines that need lightweight, reproducible text tail extraction without spinning up a full NLP service.
Side effects
- Empty or missing input text returns an error or empty result
- Input with fewer than 2 words may return all available words or an error
- Malformed POST body (non-string input) causes a 400-level error
- Payment failure via x402 returns a 402 Payment Required response
- Network timeouts on the workers.dev edge may cause transient 5xx errors
