# StableStudio GPT-Image-2 Generate

> StableStudio GPT-Image-2 Generate is a paid API for AI agents from stablestudio.io, paid per call via x402, $10/call, status unknown (last checked 2026-09-13).

Generates AI images using the GPT-Image-2 model via a pay-per-generation endpoint, returning a job ID for async retrieval.

## Facts

- Endpoint: POST https://stablestudio.io/api/generate/gpt-image-2/generate
- Price: $10/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/stablestudio-gpt-image-2-generate-9912f57a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_esIW9BLe_TmdSExr6LCKL

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 stablestudio-gpt-image-2-generate-9912f57a -d '<json body>'
```

Example prompt: Generate an image of a futuristic cityscape at sunset with neon lights reflecting on wet streets, photorealistic style — using StableStudio's pay-per-generation GPT-Image-2 model.

## When to prefer this

Choose this endpoint when you need GPT-Image-2 quality images without committing to a subscription, especially for sporadic or agent-driven image generation workflows where pay-per-call economics are preferable. Ideal for autonomous agents that generate images on demand and need crypto-native (USDC) payment via x402 protocol.

## Known failure modes

- Insufficient USDC balance causes payment failure and rejected request
- Invalid or missing prompt returns error
- Model unavailable or overloaded returns service error
- Malformed request body causes 400 error
- Job created but image generation fails asynchronously — status will reflect failure on polling

## How this service works

Pay-per-generation AI image and video creation. No subscriptions ever.

## Output

Returns a JSON object with the generation type ('gpt-image-2-generate'), a unique jobId for polling the result, a status field (initially 'pending'), and a success boolean indicating the job was accepted.
