# Stability AI Stable Fast 3D via Locus x402

> Stability AI Stable Fast 3D via Locus x402 is a paid API for AI agents from stability-ai.x402.paywithlocus.com, paid per call via x402, $0.115/call, status unknown (last checked 2026-09-14).

Converts a single 2D image of an object into a 3D model using Stability AI's Stable Fast 3D, with configurable mesh type and texture resolution.

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 stability-ai-stable-fast-3d-via-locus-x402-f075da72 -d '<json body>'
```

Example prompt: Take this product photo and generate a 3D model from it using Stable Fast 3D — use quad remeshing, set the foreground ratio to 0.85, and render it at 2048 texture resolution.

## When to prefer this

Choose this endpoint when you need to lift a 2D object photograph into a full 3D mesh with texture in a single API call, especially for e-commerce, game asset pipelines, or AR/VR workflows. It is backed directly by Stability AI's Stable Fast 3D model, making it preferable over generic 3D reconstruction services when quality and speed matter. Use it when you need control over mesh topology (none/triangle/quad) and texture resolution (512–2048).

## Known failure modes

- Image does not contain a clear foreground object — poor segmentation or mesh quality
- Invalid remesh value (must be none, triangle, or quad) — API may reject or default silently
- Texture resolution not one of 512/1024/2048 — may cause validation error
- Image URL inaccessible or malformed — request fails with input error
- Payment insufficient or USDC wallet not funded — 402 payment required error
- Async job timeout — status URL may return pending indefinitely for complex inputs

## How this service works

Generative AI platform for images, 3D models, and audio — text-to-image, editing, upscaling, and more.

## Output

Returns a JSON response with a request ID and a status URL to poll for the completed 3D model asset, along with payment confirmation details (settled and authorized USDC amounts) and a success flag. The actual 3D mesh data is retrieved asynchronously via the status URL.
