# three.ws 3D Avatar Model Validation Sweep

> three.ws 3D Avatar Model Validation Sweep is a paid API for AI agents from three.ws, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-23).

Validates and inspects a 3D avatar model (glTF/GLB), returning a quality score, mesh counts, animation counts, bone completeness, and structural diagnostics.

## Facts

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 three-ws-3d-avatar-model-validation-sweep-7b483934 -d '<json body>'
```

Example prompt: Can you run a validation sweep on my 3D avatar model and tell me the quality score, whether any bones are missing, how many animations it has, and if there are any errors?

## When to prefer this

Use this endpoint when you need to programmatically validate a 3D avatar model (glTF/GLB) for structural integrity, mesh quality, animation completeness, and bone rig correctness before deploying it as a three.ws AI agent. Prefer this over manual inspection tools when integrating avatar validation into an automated pipeline or when you need machine-readable quality scores and diagnostic counts.

## Known failure modes

- Invalid or malformed request body returns an error response
- Non-3D or unsupported file format may result in low score or error flags
- Missing required 'input' field causes schema validation failure
- Payment not provided or insufficient USDC causes 402 Payment Required
- Avatar file too large or corrupt may cause processing failure

## How this service works

Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.

## Output

Returns a JSON object with: a boolean 'ok' flag, an integer quality score (0-100), mesh/node/skin/texture/material/animation counts, total vertex and triangle counts, indexed and non-indexed primitive counts, avatar ID and name, inspection timestamp, a boolean for missing bones, a boolean for errors, list of glTF extensions used, and file size in bytes.
