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-04ea054b -d '<json body>'
```

Example prompt: Can you check if this entropy hex string is valid for BIP39 mnemonic generation: 'a3f1c2e4b5d6a7f8c9e0b1d2a3f4c5e6'?

## When to prefer this

Use this endpoint when you need to programmatically verify that a raw entropy hex string meets BIP39 specification requirements before using it to generate a mnemonic seed phrase. Prefer this over manual inspection when building wallet tools, key generation pipelines, or auditing entropy sources at scale.

## Known failure modes

- Invalid hex string format returns an error or failed status
- Entropy length not meeting BIP39 requirements (128, 160, 192, 224, or 256 bits) flagged as invalid
- Missing or empty entropy_hex field may return a validation error
- Non-hex characters in the input string cause parsing failures
- Server errors returning unexpected response shapes
