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 kihustle-cosine-similarity-bag-of-words-f58c5657 -d '<json body>'
```

Example prompt: Can you compute the cosine similarity between these two texts using bag-of-words: 'Machine learning helps automate tasks' and 'Automation with AI reduces manual work'?

## When to prefer this

Prefer this endpoint when you need a fast, lightweight, word-overlap-based similarity measure between two short-to-medium texts without needing deep semantic embeddings. Ideal for deduplication, basic relevance scoring, and keyword-overlap checks where speed and low cost matter more than nuanced semantic understanding.

## Known failure modes

- Missing text_a or text_b fields returns an error
- Empty strings may produce a zero or undefined similarity score
- Very long texts may hit request size limits
- Non-string inputs may cause a validation error
- Server errors return a non-success status field

## Output

Returns a JSON object with a cosine similarity score (a float between 0 and 1, where 1 means identical and 0 means no overlap) and a success status field indicating whether the computation completed successfully.
