OpenAI SDK Drop-in

from openai import OpenAI

client = OpenAI(
    api_key="your-token-here",

Gotchas

• 100% OpenAI-compatible — use the standard OpenAI SDK with base_url="https://api.acedata.cloud/v1"
• Billing is token-based with per-model pricing (more expensive models cost more per token)
• Vision is supported on multimodal models (gpt-4o, gpt-4o-mini, grok-2-vision-*)
• Function calling works on most modern models (GPT-4+, Claude 3+)
• Streaming returns chat.completion.chunk objects via SSE
• finish_reason values: "stop" (complete), "length" (max tokens), "tool_calls" (function call), "content_filter" (filtered)

Stateful Conversations Endpoint

For stateful, session-based chat (no need to send the full history each time), use the /aichat/conversations endpoint:

curl -X POST https://api.acedata.cloud/aichat/conversations \
  -H "Authorization: Bearer $ACEDATACLOUD_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"model": "gpt-4.1", "question": "What is quantum computing?", "stateful": true}'

Parameter	Type	Description
model	string	Model name (see Available Models above)
question	string	The prompt or question to answer
id	string	Conversation ID — pass the same ID to continue a session
preset	string	Preset/system prompt for the conversation
stateful	boolean	Enable stateful conversation (maintains history server-side)
references	array	Additional context documents to include
