Example Prompts for Claude Desktop

Once configured, you can use these natural language prompts in Claude Desktop:

Basic Health Check

Check the OpenSincera API connection status

Publisher Domain Lookup

Get publisher information for yahoo.com from OpenSincera

Detailed Analysis Request

Analyze the publisher metrics for cnn.com and explain: - Their verification status - Ad to content ratio and what it means - Supply chain complexity - Overall advertising quality

Multiple Domain Comparison

Compare the following publishers using OpenSincera data: - nytimes.com - washingtonpost.com - reuters.com Focus on their verification status, ad quality metrics, and supply chain efficiency.

Publisher ID Lookup

Get detailed information for OpenSincera Publisher ID 2737

Targeted Metric Analysis

For the domain example.com, explain: - What is their ID Absorption Rate and why does it matter? - How does their page weight affect ad performance? - Are they using too many resellers?

Business Context Questions

I'm considering running ad campaigns on forbes.com. Can you check their OpenSincera profile and tell me: - Is this a verified publisher? - What's their ad refresh rate and is it good or bad? - How many supply paths do they have? - Would you recommend this publisher for quality ad placement?

These prompts will automatically trigger the appropriate OpenSincera MCP tools and return formatted responses with detailed metric explanations.
