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 metallic-roughness-packer-mcp-f824d06c -d '<json body>'
```

Example prompt: Pack my metallic and roughness texture maps into a single combined PBR texture — here's the base64-encoded image data for both channels.

## When to prefer this

Choose this endpoint when you need to pack separate metallic and roughness PBR texture channels into a single combined texture map for use in GLTF pipelines, game engines (Unreal, Unity), or WebGL renderers like Three.js. Prefer this over manual image editing when automating texture pipeline steps in an agentic workflow.

## Known failure modes

- Invalid or malformed base64 image data returns an error
- Input data string missing or empty causes processing failure
- Unsupported texture format or resolution may result in rejection
- Mismatched channel dimensions between metallic and roughness inputs

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

A processed, channel-packed texture combining metallic and roughness data into a single PBR-compatible image asset, suitable for use in GLTF, game engines, or WebGL renderers.
