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-bip39-entropy-checker-3fbc6d8b -d '<json body>'
```

Example prompt: Can you check whether this entropy hex string is valid for BIP39 use: 'a3f2c8e1b0d74f9265aec3810d2b7f4a'?

## When to prefer this

Use this endpoint when you need to programmatically validate BIP39 entropy hex strings before using them in wallet generation or seed phrase derivation. Prefer this over manual checks when building automated crypto wallet tooling or verifying user-supplied entropy inputs.

## Known failure modes

- Invalid or malformed hex string returns error status
- Entropy of incorrect length for BIP39 (not 128, 160, 192, 224, or 256 bits) may fail validation
- Empty input or missing entropy_hex field causes processing failure
- Non-hex characters in the input string cause rejection
