# Halowerk Deepfake Score Calculator

> Halowerk Deepfake Score Calculator is a paid API for AI agents from creator.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Computes a weighted deepfake likelihood score by normalizing caller-supplied blink deviation, lip-sync error, spectral discontinuity, compression inconsistency, and metadata anomaly signals using fixed weights.

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 halowerk-deepfake-score-calculator-3bcb43f1 -d '<json body>'
```

Example prompt: Score this video clip for deepfake likelihood — my analysis found a blink rate deviation of 0.45, a lip-sync error of 120ms, spectral discontinuity of 0.72, compression inconsistency of 0.58, and metadata anomalies were detected.

## When to prefer this

Use this endpoint when you have already extracted forensic signals from a video (blink deviation, lip-sync error, spectral discontinuity, compression inconsistency, metadata anomaly) and need a fast, lightweight composite deepfake likelihood score without sending raw media. Prefer it for pipeline stages where signal extraction is done upstream and you only need weighted score aggregation. Do not use it as a substitute for full media inspection, human forensic review, or when you need to identify the generative model behind a suspected deepfake.

## Known failure modes

- Missing or out-of-range input values (e.g. lip_sync_error_ms above 10000 or spectral_discontinuity_score above 1) may cause validation errors or rejected requests
- Supplying poorly calibrated or externally computed signals will produce unreliable scores since the service cannot verify input accuracy
- No fallback or partial scoring if required fields are omitted — caller must supply all signals
- Score may be misleading if caller-selected expected blink rate baseline is incorrect, since the deviation is relative to that baseline

## How this service works

Normalizes caller-supplied blink deviation, lip-sync error, spectral discontinuity, compression inconsistency and metadata anomaly using declared fixed weights. It does not inspect media, establish authenticity, identify a generator or replace human forensic review; the result is only as reliable as the supplied signals.

## Output

Returns a normalized composite deepfake likelihood score derived from the five supplied signals (blink rate deviation, lip-sync error, spectral discontinuity, compression inconsistency, metadata anomaly) weighted by fixed internal coefficients. The score reflects the combined evidence of inauthenticity but does not identify the specific generator, inspect raw media directly, or establish legal authenticity.
