# ONE Engine Word Bigrams Tokenizer

> ONE Engine Word Bigrams Tokenizer is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).

Extracts word-level bigrams (consecutive two-word pairs) from input text up to 50,000 characters.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability one-engine-word-bigrams-tokenizer-b373c81c -d '<json body>'
```

Example prompt: Extract all word bigrams from this text: 'The quick brown fox jumps over the lazy dog' — I need consecutive two-word pairs for NLP preprocessing.

## When to prefer this

Choose this endpoint when you need fast, low-cost word bigram extraction for NLP preprocessing tasks and are already using x402 micropayments on Base. At $0.0005 USDC per call it is ideal for high-volume text processing pipelines where you need to tokenize many documents cheaply without managing a local NLP library.

## Known failure modes

- Text exceeding 50,000 characters may be rejected or truncated
- Empty or whitespace-only text may return empty bigram set
- Payment failure via x402 on Base will prevent access
- Malformed JSON request body returns error
- Single-word input produces no bigrams

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object containing the word bigrams extracted from the input text — consecutive pairs of adjacent words as they appear in sequence across the submitted string.
