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 cosine-similarity-bag-of-words-kihustle-bot-bazaar-19f2cb29 -d '<json body>'
```

Example prompt: Can you check how similar these two sentences are using bag-of-words cosine similarity? First: 'Earn money online with AI tools and automation.' Second: 'Use artificial intelligence to build passive income streams online.'

## When to prefer this

Choose this endpoint when you need a fast, lightweight, lexical similarity measure between two short-to-medium text strings and do not need semantic embedding-based comparison. It is ideal for deduplication, keyword matching, and basic relevance scoring where vocabulary overlap is a sufficient proxy for similarity. Prefer semantic embedding endpoints when deep semantic meaning matters more than word overlap.

## Known failure modes

- Missing text_a or text_b fields returns an error
- Empty string inputs may yield a zero-similarity result or error
- Very long texts may cause unexpected truncation or timeout
- Non-UTF-8 or special character inputs may cause parsing failures
- Response schema is minimal — numeric score format not guaranteed beyond 'result' and 'status' fields

## Output

Returns a JSON object with a similarity result and status field. The similarity score reflects how close the two input texts are based on overlapping vocabulary weighted by cosine distance using a bag-of-words model. A score of 1.0 indicates identical term distributions; 0.0 indicates no overlap.
