# TITANHOLD AI Quality Check

> TITANHOLD AI Quality Check is a paid API for AI agents from x402.titanhold.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-20).

Analyzes an AI-generated image or short video for common generation defects such as extra fingers, garbled text, wrong vehicle geometry, physics errors, and flicker, returning a pass/fail score with detailed defect annotations.

## 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 titanhold-ai-quality-check-09429747 -d '<json body>'
```

Example prompt: Can you quality-check this AI-generated image for me — the URL is https://cdn.example.com/output.png — I ordered a sports car on a racetrack, and I want it to fail if the score drops below 75? Flag any anatomy, vehicle geometry, or text issues.

## When to prefer this

Choose this endpoint when you need automated defect detection specifically for AI-generated images or short videos — particularly for anatomy errors (extra fingers, distorted faces), vehicle geometry, garbled text, flicker, and physics impossibilities. It is purpose-built for AI generation artifacts rather than generic image quality metrics, and includes brief-aware evaluation so defects are judged against what was actually ordered. Prefer it over generic computer vision APIs when the content is AI-generated and you need a structured pass/fail gate with per-defect severity ratings.

## Known failure modes

- File URL unreachable or returns non-200 — check returns error without score
- Base64 data malformed or too large — parsing failure
- Unsupported file format — model cannot process the media type
- frames parameter outside 2-8 range — validation error
- minScore outside 0-100 range — validation error
- brief exceeds 500 characters — truncated or rejected
- Vision model inference timeout for very long videos
- Payment not included or insufficient — 402 Payment Required response

## How this service works

Paid check of an AI-generated image or short video for typical generation defects (extra fingers, garbled text, wrong vehicle geometry, physics, flicker). Runs a local vision model; files are deleted after the check.

## Output

Returns a JSON object with: the media kind (image or video), a pass/fail boolean, the vision model used, a 0-100 quality score, a list of detected defects each with type/detail/severity, human-readable reasons for failure, and the number of frames checked. Files are deleted after analysis.
