​
Prerequisites

Before you begin, ensure you have:
  • An OpenAI account
  • API access to create and configure custom GPTs
  • A Dappier API Key (Get it from Dappier API Keys)

​
Step 1: Access the GPT Builder

  1. Navigate to OpenAI’s Custom GPT Page
  2. Log in to your OpenAI account
  3. Click on “Create a GPT” to begin customization

​
Step 2: Define GPT Characteristics

​
Name

Set the GPT’s name to Dappier Stock & Financial News Analyst

​
Description

Use the following description:
Delivers stock trend analysis and financial insights with ticker-specific investment context.

​
Instructions

This GPT provides structured financial insights by analyzing:
  • Market trends
  • Stock prices
  • Financial news
When answering financial queries, it:
  • Reformulates prompts to ensure comprehensive investment insights before calling the Dappier API.
  • Ensures all queries contain a stock ticker symbol (required by the Dappier API).
  • Requests all relevant market trends and financial data before providing insights.
  • Prioritizes concise, actionable insights rather than generic news updates.
  • Avoids making direct investment recommendations but helps users interpret data effectively.
The GPT will not process API queries unless the required ticker information is included.

​
Step 3: Configure API Integration

​
API Endpoint

Your GPT will communicate with the Dappier Stock & Financial Data API at: 
https://api.dappier.com/app/aimodel/am_01j749h8pbf7ns8r1bq9s2evrh

​
Authentication

Use Bearer Token authentication. Include the API key in the Authorization header: 
Authorization: Bearer <your_api_key>

​
Request Body Format

Send queries in JSON format: 
{
  "query": "Analyze stock trends of AAPL and TSLA with the latest market insights."
}

​
Example API Request (cURL)

curl -X POST "https://api.dappier.com/app/aimodel/am_01j749h8pbf7ns8r1bq9s2evrh" \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"query": "Analyze stock trends of AAPL and TSLA with the latest market insights."}'

​
Step 4: Configure Capabilities

  • Can you summarize key takeaways from today’s market movement for TSLA and AMZN?
  • Which stocks (AAPL, NVDA, TSLA) are gaining the most from recent economic policy changes?

    "description": "Fetch real-time AI stock and financial insights with web search integration using Dappier's API. AI generates quick investment insights based on trending financial news and analysis.",
    "version": "v1.0.0"
  },
  "servers": [
    {
      "url": "https://api.dappier.com"
    }
  ],
  "paths": {
    "/app/aimodel/am_01j749h8pbf7ns8r1bq9s2evrh": {
      "post": {
        "description": "Query real-time stock and financial news data from Dappier, including market trends, financial news, and investment insights.",
        "operationId": "getRealTimeFinancialData",
        "requestBody": {
          "required": true,
          "content": {
            "application/json": {
              "schema": {
                "$ref": "#/components/schemas/QueryRequest"
              }
            }
          }
        },
        "responses": {
          "200": {
            "description": "Successful response with real-time financial insights",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/QueryResponse"
                }
              }
            }
          }
        },
        "security": [
          {
            "ApiKeyBearer": []
          }
        ]
      }
    }
  }
}

​
Step 6: Test and Iterate

  1. Use the OpenAI GPT interface to test queries like:
    • “Analyze stock trends of AAPL and TSLA with the latest financial news.”
    • “What are the top investment insights from today’s market trends?”
  2. Ensure responses are accurate and formatted correctly.
  3. Refine GPT behavior by adjusting instructions as needed.

​
Step 7: Deploy and Share

Once finalized, you can:
  • Share your GPT publicly or privately
  • Embed it in financial applications
  • Continuously refine it based on feedback
Sharing Options:
  • Private: Only accessible to you
  • Unlisted: Accessible via a direct link
  • Public: Available in the GPT Store

​
Privacy & Security

  • All API interactions must comply with OpenAI and Dappier’s terms.
  • Keep your API key secure and do not expose it publicly.
  • Review Dappier’s Privacy Policy for more details.
