OpenClaw x GPT Image

GPT Image is OpenAI's image generation model, supporting text-to-image and image editing. Through RunAPI, all GPT Image endpoints share one key and per-call pricing.

Public versions and endpoints

Configuration

Guide endpoint: /api/v1/gpt_image/text_to_image

export RUNAPI_API_KEY=your_api_key

curl -X POST https://runapi.ai/api/v1/gpt_image/text_to_image \
  -H "Authorization: Bearer $RUNAPI_API_KEY" \

}'

Verify

POST /api/v1/gpt_image/text_to_image and save the returned Task id.
GET /api/v1/gpt_image/text_to_image/<task-id> until status is completed or failed.
Verify the completed response contains the endpoint-specific output documented in the API reference.

How it works

1. Choose a model ID
Select a public catalog model ID and review its endpoint and current starting price.
2. Configure RunAPI
Set RUNAPI_API_KEY before making the endpoint request.
3. Verify the result
For asynchronous endpoints, poll the same endpoint until the Task reaches a terminal status.
