# KiHustle Word Embedding Similarity Proxy

> KiHustle Word Embedding Similarity Proxy is a paid API for AI agents from kihustle.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Computes word embedding similarity for a given text string via a proxy API, returning a processed similarity result.

## Facts

- Endpoint: POST https://kihustle.tech/agents/api/v1/word-embed-similarity-proxy
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

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-word-embedding-similarity-proxy-f539e916 -d '<json body>'
```

Example prompt: Can you compute the word embedding similarity for the text 'machine learning automation' and give me the similarity result?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call word embedding similarity computation without setting up your own ML infrastructure. It is suitable for quick semantic similarity checks on individual text strings at low cost ($0.002 USDC per call). Prefer alternatives if you need batch processing, explicit cosine similarity scores, or a well-documented embedding model with known dimensions.

## Known failure modes

- Missing or empty 'text' field in request body returns an error
- Oversized text input may exceed processing limits
- Network or proxy upstream failure resulting in non-200 response
- Payment failure (x402) if USDC balance is insufficient
- Ambiguous or malformed JSON body causes parsing errors
