Documentation: Node.js Script for Private Blockchain Deep Search via RapidAPI

Introduction

This document provides an in-depth guide for a Node.js script designed to interact with a private blockchain search service through RapidAPI. The script employs axios, a popular HTTP client, for sending POST requests.

Setup and Dependencies

1. Environment: Node.js.
2. Library: axios (Install via npm install axios if not present).

Script Breakdown

1. Importing Dependencies

   const axios = require('axios');
   

   • Purpose: Includes the axios library for HTTP requests.

2. API Request Configuration

   const options = {
     method: 'POST',
     url: 'https://private-blockchain-deep-search-layer.p.rapidapi.com/v1/custom/search/v1',
     params: { query: '<REQUIRED>' },
     headers: {
       'content-type': 'application/json',
       'X-RapidAPI-Key': 'YOUR_API_KEY',
       'X-RapidAPI-Host': 'private-blockchain-deep-search-layer.p.rapidapi.com'
     },
     data: { query: 'hello', secret_key: '' }
   };
   

   • Components:
     • method, url: Defines the request type and target endpoint.
     • params: Contains search parameters. Replace <REQUIRED> with actual query.
     • headers: Essential headers including API key (replace YOUR_API_KEY).
     • data: Payload of the POST request with query and potential secret key.

3. Executing the Request

   try {
     const response = await axios.request(options);
     console.log(response.data);
   } catch (error) {
     console.error(error);
   }
   

   • Functionality:
     • Try Block: Executes the request and logs the response.
     • Catch Block: Catches and logs any errors encountered.

Usage Guidelines

1. Query Replacement: Ensure the query in params and data reflects your search needs.
2. API Key Insertion: Input your valid RapidAPI key in the headers.
3. Adjust secret_key: Modify if necessary for blockchain network access.
4. Execution: Run in a Node.js environment.

Security and Error Handling

• API Key Management: Securely store and use the API key to prevent unauthorized access.
• Response Handling: Familiarize with the API’s response structure for effective data processing.
• Error Management: Implement comprehensive error handling for different failure scenarios.
