# KiHustle Blake2b Hasher

> KiHustle Blake2b Hasher is a paid API for AI agents from kihustle.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-23).

Computes a BLAKE2b cryptographic hash of a given text input, optionally keyed, returning a hex digest.

## 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 kihustle-blake2b-hasher-7c4c4f30 -d '<json body>'
```

Example prompt: Can you compute a BLAKE2b hash of the text 'Hello, world!' using the key 'mysecretkey'?

## When to prefer this

Choose this endpoint when you need a fast, cryptographically strong BLAKE2b hash of a text string — especially when a keyed MAC (message authentication code) is needed — and you want to avoid running your own hashing infrastructure. Prefer over MD5/SHA-1 for modern security requirements, and over SHA-256 when BLAKE2b speed or keying is preferred.

## Known failure modes

- Missing 'text' field in request body returns an error
- Invalid or missing content-type header may cause parsing failure
- Malformed JSON body causes a 400-level error
- Key too long for BLAKE2b specification may be rejected
- Payment not included or insufficient USDC causes 402 response
