Get your Ace Data Cloud API key

Open Ace Data Cloud → Applications. Sign in, or register an account first.
Find General application. If it has not been created, choose Initialize General Application. A general key can use the services available to your account; a dedicated application's key is limited to its service. Check the required service/model access and current pricing.
Copy the API Key from the application card, or open Keys / Manage Keys → Create to create a separate key for this integration. Give it a recognizable name so you can revoke or rotate it independently.
When creating a key, review Expiration Time, Set Usage Limitation, and Allowed APIs. Enable only the restrictions you need, allow the operations you will call, then click Create and copy the token from the key list. Task lookup does not grant permission to submit a generation. Confirm the application's balance can cover your first request; any trial allowance is whatever your account currently displays.
Copy only the token value, without quotation marks, spaces, or Bearer . An API Key / API Token field expects this raw value; only a manually configured HTTP Authorization header needs the Bearer prefix. A platform-... account-management token cannot replace a generation API key.

Save the key in the client's credential store or the environment variable shown below. Never put it in a prompt, shared workflow, screenshot, or Git commit. If authentication fails, check the full copied value, application/service access, expiration, usage limit, and balance before creating another key.

Frequently Asked Questions

Common questions about using the OpenAI API

What is the difference between using this and directly using the official OpenAI API?›

Ace Data Cloud provides a proxy interface fully compatible with the official OpenAI format, without the need to register an OpenAI account or bind an overseas credit card. One API Key can access multiple models such as OpenAI, Claude, Gemini, Grok, etc.

What is the difference between GPT-5 and GPT-4o?›

GPT-5 is a high-end flagship-tier model (the newest being the GPT-5.6 series), surpassing GPT-4o in reasoning, creativity, and knowledge capabilities. GPT-4o is a well-validated cost-effective choice, suitable for cost-sensitive scenarios.

What scenarios are the o series reasoning models suitable for?›

Models like o3, o3-pro, and o4-mini perform deep thinking before providing answers, particularly suitable for tasks requiring deep reasoning such as mathematical calculations, logical reasoning, and code analysis. o3-mini and o4-mini offer lower-cost reasoning capabilities.

What is the difference between GPT Image and DALL·E 3?›

GPT Image models support both generation and editing. GPT Image 2.5 Flare prioritizes speed, while Sunburst prioritizes higher-fidelity output and finer control. Each 2.5 model also has an :official variant billed from actual token usage. DALL·E 3 remains a dedicated generation model with Standard and HD modes.

Which model is good for Embeddings?›

It is recommended to use text-embedding-3-small, which has the best cost-performance ratio ($0.0027 / million Tokens). For higher precision, use text-embedding-3-large ($0.017 / million Tokens). The older ada-002 is no longer available; existing vector indexes must be rebuilt before switching models.
