# StableMesh Text-to-3D Model Generation

> StableMesh Text-to-3D Model Generation is a paid API for AI agents from stablemesh.dev, paid per call via x402, $1/call, status unknown (last checked 2026-09-14).

Generates a 3D model from a text prompt using AI, charged at $1 USDC per request with no API key or subscription required

## Facts

- Endpoint: POST https://stablemesh.dev/api/text-to-3d
- Price: $1/call
- Payment: x402
- Status: unknown

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 stablemesh-text-to-3d-model-generation-0b075c0b -d '<json body>'
```

Example prompt: Generate a 3D model of a low-poly wooden treasure chest with iron hinges and a lock — I need a mesh I can use in a game scene.

## When to prefer this

Choose this endpoint when you need on-demand AI-generated 3D models without committing to a subscription or managing API keys — ideal for one-off asset generation, prototyping, or pay-as-you-go workflows where you want to pay $1 USDC per model via the x402 protocol

## Known failure modes

- Payment not received or insufficient USDC — request rejected with payment-required error
- Ambiguous or overly complex text prompt may yield a low-quality or malformed mesh
- Timeout if generation takes too long for complex prompts
- Invalid or malformed request body returns a 400 error
- Service unavailable or generation pipeline failure returns a 5xx error

## How this service works

Pay-per-request AI 3D model generation. No API keys, no subscriptions.

## Output

A JSON response containing the generated 3D model data or a reference to the mesh file produced from the input text prompt
