Overview

The BLACKBOX AI API provides powerful web search capabilities through the blackbox-search model. This feature allows your AI applications to access real-time information from the web, providing up-to-date answers with cited sources.

​
Key Features

  • Real-time Information: Access current data from the web
  • Source Citations: Get URLs and titles of sources used
  • Seamless Integration: Works with the standard chat completions API
  • Automatic Context: Web results are automatically incorporated into responses
To enable web search, simply use the blackbox-search model in your chat completion requests: 
curl --location 'https://api.blackbox.ai/v1/chat/completions' \
--header 'Authorization: Bearer YOUR_API_KEY' \
--header 'Content-Type: application/json' \
--data '{
  "model": "blackbox-search",
  "messages": [
    {
      "role": "system",
      "content": "You are a helpful assistant that provides accurate, up-to-date information."
    },
    {
      "role": "user",
      "content": "What are the latest developments in AI from OpenAI?"
    }
  ],
}'

​
Response Format

When using web search, the response includes an annotations array containing URL citations: 
{
  "id": "gen-...",
  "created": 1757140020,
  "model": "blackbox-search",
  "object": "chat.completion",
  "choices": [
    {
      "finish_reason": "stop",
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "Here's the latest news I found: OpenAI recently announced...",
        "annotations": [
          {
            "type": "url_citation",
            "url_citation": {
              "url": "https://www.example.com/openai-news",
              "title": "Latest OpenAI Developments",
              "content": "Content of the web search result",
              "start_index": 100,
              "end_index": 200
            }
          }
        ]
      }
    }
  ],

    model="blackbox-search",
    messages=[
        {"role": "user", "content": "What are today's top technology news?"}
    ]

Research and Fact-Checking
response = client.chat.completions.create(

    ]
)
Product Information
response = client.chat.completions.create(
    model="blackbox-search",
    messages=[
        {"role": "user", "content": "Compare the latest iPhone and Samsung Galaxy models"}
    ]
)
Market Data
response = client.chat.completions.create(

    ]
)

​
Best Practices

  1. Be Specific: Provide clear, specific queries for better search results
  2. Use System Messages: Set context about the type of information needed
  3. Handle Citations: Always check for and display source citations to users
  4. Rate Limiting: Be mindful of API rate limits when making frequent searches
  5. Verify Information: While web search provides current data, always encourage users to verify critical information
Web search works seamlessly with streaming responses: 
stream = client.chat.completions.create(
    model="blackbox-search",
    messages=[
        {"role": "user", "content": "Latest AI breakthroughs in 2025"}
    ],
    stream=True
)

for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)
