Prerequisites

1. API Key

First, you'll need a ScrapeCreators API key to authenticate your requests.

Sign up at app.scrapecreators.com to get your free API key with 100 requests.

2. Development Environment

Make sure you have the following installed:

  • • Rust and its dependencies
  • • A code editor (VS Code, Sublime, etc.)
  • • Basic understanding of API requests
  • • Command line interface access

Step 1: Install HTTP Client

Reqwest is a high-level HTTP client for Rust

cargo
cargo add reqwest

Step 2: API Implementation

Now let's make a request to the Bluesky API using Rust. Replace YOUR_API_KEY with your actual API key.

Rust
use reqwest;
use std::collections::HashMap;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let result = scrape().await?;
    println!("Response: {}", result);
    Ok(())
}

async fn scrape() -> Result<String, Box<dyn std::error::Error>> {
    let client = reqwest::Client::new();
    
    // Build query parameters
    let mut params = HashMap::new();
    params.insert("handle".to_string(), "espn.com".to_string());
    params.insert("user_id".to_string(), "did:plc:x7d6j54pm22ufehkes6jo4jf".to_string());
    
    let response = client
        .get("https://api.scrapecreators.com/bluesky/user/posts")
        .header("x-api-key", "YOUR_API_KEY")
        .header("Content-Type", "application/json")
        .query(&params)
        .send()
        .await?;
    
    if response.status().is_success() {
        let body = response.text().await?;
        Ok(body)
    } else {
        Err(format!("HTTP {}: {}", response.status(), response.text().await?).into())
    }
}

Step 3: Testing Your Code

API Parameters

This endpoint accepts the following parameters:

handleOptional(string)

Bluesky handle

Example: espn.com

user_idOptional(string)

Bluesky 'did'. (For some reason Bluesky calls their user ids, 'did' for whatever reason)

Example: did:plc:x7d6j54pm22ufehkes6jo4jf

Run Your Code

Execute your script to test the API connection. You should see a JSON response with Bluesky posts data.

✅ Success: You should receive a structured JSON response containing the requested data.

Expected Response

Here's an example of the JSON response you'll receive:

Best Practices

1

Error Handling

Implement comprehensive error handling and retry logic for failed requests. Log errors properly for debugging.

2

Caching

Cache responses when possible to reduce API calls and improve performance. Consider data freshness requirements.

3

Security

Never expose your API key in client-side code. Use environment variables and secure key management practices.

Performance Tips

Batch Requests

When scraping multiple posts, consider batching requests to maximize throughput while staying within rate limits.

Async Processing

Use asynchronous processing in Rust to handle multiple requests concurrently and improve overall performance.

Common Use Cases

Troubleshooting

Common Errors

401 Unauthorized

Check your API key is correct and properly formatted in the x-api-key header.

402 Payment Required

You ran out of credits and need to buy more.

404 Not Found

The resource might not exist or be private.

500 Server Error

Temporary server issue. Implement retry logic with exponential backoff.
