# PayWeave Replicate – GPT-Image-2 Image Generation

> PayWeave Replicate – GPT-Image-2 Image Generation is a paid API for AI agents from replicate.payweave.services, paid per call via x402, $0.03/call, status healthy (last checked 2026-09-16, last successful call 2026-08-29).

Runs OpenAI's GPT-Image-2 model via Replicate to generate images from prompts, payable per-call with USDC.

## Facts

- Endpoint: POST https://replicate.payweave.services/models/openai/gpt-image-2/predictions
- Price: $0.03/call
- Payment: x402
- Status: healthy
- Last checked: 2026-09-16
- Last successful call: 2026-08-29
- Success rate: 96% of calls made through Zero
- Activations on Zero: 52
- Tags: x402
- Canonical page: https://www.zero.xyz/c/payweave-replicate-gpt-image-2-image-generation-60de31fd
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_uzubWVP9n0sE8lkuXOUKZ

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 payweave-replicate-gpt-image-2-image-generation-60de31fd -d '<json body>'
```

Example prompt: Generate an image of a futuristic cityscape at sunset with neon lights reflecting on wet streets using the GPT-Image-2 model.

## When to prefer this

Choose this endpoint when you need on-demand image generation using OpenAI's GPT-Image-2 model specifically, want pay-per-call USDC billing with no subscription, and are comfortable with Replicate-hosted CDN output URLs that expire after 24 hours. Prefer over self-hosted or subscription-based alternatives when cost predictability per image and access to the latest OpenAI image model via a simple POST are priorities.

## Known failure modes

- Model inference fails — status returns 'failed' with a non-null error message
- Payment rejected or insufficient USDC balance — 402 Payment Required before inference runs
- Invalid or missing input object — 422 validation error returned
- Replicate backend timeout — status may remain 'processing' or return 'canceled'
- CDN URL expires after ~24 hours — output image URL becomes inaccessible

## How this service works

Run open-source AI models — image, video, audio.

## Output

Returns a Replicate prediction object containing a prediction ID, the model name, a status (succeeded/failed/canceled/processing/starting), a CDN-hosted image URL with ~24h TTL as the output, timing metrics (total_time, predict_time), timestamps, and the USD amount charged for the call.
