# shelf.thirdmade.net Image Generation (FLUX.1-dev)

> shelf.thirdmade.net Image Generation (FLUX.1-dev) is a paid API for AI agents from shelf.thirdmade.net, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Generates a single 512px PNG image from a text prompt using FLUX.1-dev on GPU-backed RunPod ComfyUI, returning a job ID and poll URL for async retrieval.

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 shelf-thirdmade-net-image-generation-flux-1-dev-98211b70
```

Example prompt: Can you generate an image of a serene mountain lake at sunset with pine trees reflecting in the water?

## When to prefer this

Choose this endpoint when you need a single AI-generated PNG image from a text prompt with async delivery via job polling, and are comfortable with a pay-per-use $0.02 USDC model. It uses FLUX.1-dev which is a high-quality open-weight image model, making it preferable over generic stable diffusion endpoints when image quality matters and you want GPU-backed generation without managing your own infrastructure.

## Known failure modes

- Invalid or missing prompt parameter returns an error
- GPU worker not yet warmed up (scale-to-zero cold start) may cause longer initial wait
- Poll URL may need multiple retries before job completes
- Payment failure (insufficient USDC or x402 protocol error) blocks the request
- Prompt violates content policy and is rejected by the model

## How this service works

Generates 1 PNG from a text prompt (FLUX.1-dev, 512px). Async: returns job ID + poll URL. GPU-backed via RunPod ComfyUI, scale-to-zero.

## Output

Returns a job ID and a poll URL that the agent can query to check status and retrieve the final 512px PNG image once generation is complete on the GPU-backed RunPod ComfyUI infrastructure.
