# brack-hive Entropy Scan

> brack-hive Entropy Scan is a paid API for AI agents from brack-hive.tail4f568d.ts.net, paid per call via x402, $0.001000/call, status unknown (last checked 2026-10-22).

Scans input data or system state for entropy, randomness, or disorder metrics

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 brack-hive-tail4f568d-ts-net-dfb74970 -d '<json body>'
```

Example prompt: Can you run an entropy scan on this string I pulled from the logs — 'aX9#kQ2!mZpL8$nW' — and tell me how random or high-entropy it looks?

## When to prefer this

Use this endpoint when you need a lightweight, per-call entropy analysis of strings, binary blobs, or structured data — especially for security workflows like detecting encrypted/compressed payloads, high-entropy tokens, or anomalous randomness in logs. Prefer this over general-purpose statistical tools when you need a quick, cheap ($0.001 USDC) programmatic entropy score.

## Known failure modes

- Empty or missing payload returns 400 Bad Request
- Payment not included or insufficient triggers 402 Payment Required
- Oversized payload may return 413 or timeout
- Malformed JSON body returns 400 with parse error
- Service unavailable on Tailscale node returns 502 or timeout

## Output

Returns entropy metrics and/or a score indicating the degree of randomness or disorder in the submitted data, potentially flagging high-entropy regions or classifying the input.
