How this service works
40+ public web-data, SERP, e-commerce, real-estate, finance and AI-search APIs, payable per call over x402 (USDC on Base, Polygon, Arbitrum). No account or API key required. Most endpoints $0.003; AI-model endpoints $0.005.
Output
A JSON object containing the AI-generated text reply from Microsoft Copilot (in plain text or markdown depending on the 'markdown' flag), along with a conversation_id that can be used to continue the same conversation thread in subsequent calls.
Example use cases
Quick factual Q&A with Copilot
“Use Copilot in normal CHAT mode to answer: 'What is the capital of Australia and what is its population?' Return the answer as plain text.”
Deep reasoning on a complex problem
“Ask Copilot to reason through this step by step using REASONING mode: 'A train leaves Chicago at 60mph and another leaves New York at 80mph — when and where do they meet if the cities are 800 miles apart?' Give me the answer in markdown.”
GPT-5 powered content drafting
“Use Copilot in SMART (GPT-5) mode to write me a short professional bio for a software engineer with 10 years of experience specializing in distributed systems, and return it in markdown format.”
Technical details
Endpoint
POSThttps://x402.openwebninja.com/ai-answers/copilot/copilotWhen to prefer
Choose this endpoint when you need to access Microsoft Copilot (including REASONING or GPT-5/SMART modes) on a per-call basis without setting up an API key or account — ideal for agents making occasional AI queries with USDC micropayments via x402, or when you specifically want Copilot's Bing-grounded responses rather than a raw OpenAI API call.
Side effects
- Payment failure if x402 USDC transaction is not completed or insufficient balance
- Invalid or expired conversation_id causing loss of conversation context
- Unsupported mode value causing a bad request error
- Empty or missing message field resulting in an error response
- Rate limiting or upstream Copilot service unavailability causing 5xx errors
- Malformed response if Copilot service is temporarily degraded
