🔒 Safety Instruction for Agents

Instruct your AI Agents to check their remaining wallet balance using metadata response headers. If the headers contain X-Agent-Remaining-Balance and the amount drops below 5 PKR, direct the agent to notify the user via chat dialog to avoid runtime failures.

Interactive Code Sandbox

Perform real API tests through the proxy and watch the balance decrement instantly.

Integration Guide

            
Configure your LLMs, LangChain agents, or custom backend services to query the marketplace proxy.


            

                
1. Base URL & Header Credentials

                
All proxy endpoints use the standard marketplace host base. You must attach your custom developer key as an HTTP header name: X-Agent-API-Key.

                

                    Header Key: X-Agent-API-Key
                

                

                    Base Request Endpoint: http://127.0.0.1:8000/api/proxy/{API_NAME}
                

            


            

                
2. Error Handlers

                
If an API request fails, the proxy forwards the original error status code where possible. However, if the agent runs out of wallet balance, the proxy returns a specific 402 Payment Required code.

                
                

                    

                        
                            

                                Status Code
                                Error Description
                                Remediation Step
                            

                        
                        
                            

                                401
                                Unauthorized: API Key is invalid or missing.
                                Ensure the header X-Agent-API-Key matches the key in your developer dashboard.
                            

                            

                                402
                                Payment Required: Wallet balance is below the per-call price of target API.
                                Prompt user to top up credits in PKR using Easypaisa.
                            

                            

                                404
                                Not Found: Target API name does not exist in seed.
                                Open the explore tab and double check spelling of API name.
                            

                        
                    

                

            


            

                
3. LangChain Example Integration

                
Implement a custom python function inside LangChain tools or custom tools to make the call:

                
from langchain.agents import tool
import requests

@tool
def call_marketplace_api(api_name: str, query_params: dict = None) -> str:
    """Call a marketplace public API and pay per use. api_name should match explore catalog."""
    url = f"http://127.0.0.1:8000/api/proxy/{api_name}"
    headers = {
        "X-Agent-API-Key": "YOUR_DEVELOPER_API_KEY"
    }
    
    try:
        response = requests.get(url, headers=headers, params=query_params)
        if response.status_code == 402:
            return "Payment Required: Please notify user to top up their Easypaisa wallet."
        return response.text
    except Exception as e:
        return f"Error connecting to proxy: {str(e)}"
