## 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-jaccard-similarity-token-api-38c7dc06 -d '<json body>'
```

Example prompt: Can you calculate the Jaccard similarity between these two texts: 'the quick brown fox jumps over the lazy dog' and 'the fast brown fox leaps over the sleepy cat'?

## When to prefer this

Choose this endpoint when you need a lightweight, token-based set similarity metric between two text strings without requiring embeddings or ML models. Ideal for deduplication, near-duplicate detection, or quick similarity checks where semantic meaning is less important than lexical overlap. At $0.002 per call it is cost-effective for high-volume text comparison tasks.

## Known failure modes

- Missing text_a or text_b fields returns an error
- Empty string inputs may return a score of 0 or an error
- Extremely long texts may time out or produce unexpected results
- Non-string input types may cause processing failure
- Payment failure via x402 protocol prevents request from being processed

## Output
