如何解析仅含数组与嵌套数组、无属性名的JSON数据？

Got it, let's work through this together. That API returns a JSON object where each key is a unique identifier (like a game's AppID) and the corresponding value is an array—the first element of that array is exactly the number you need.

Here's a simplified look at the JSON structure: #

{
  "10": [0.05, "Counter-Strike", ...],
  "20": [0.10, "Team Fortress Classic", ...],
  "30": [0.15, "Day of Defeat", ...]
}

Core Logic (Works for Any Language) #

The steps are straightforward, no fancy identifiers needed:

1. Fetch and parse the JSON into a native object/dictionary.
2. Iterate over all the values of this object (each value is an array).
3. Grab the first element (index 0) from each array.

Example Code Snippets #

Python

Using requests and json modules:

import json
import requests

# Fetch the API data
response = requests.get("https://www.steamcardexchange.net/api/request.php?GetBadgePrices_Guest")
# Parse JSON into a Python dictionary
badge_data = json.loads(response.text)

# Extract the first number from every entry
first_numbers = [entry[0] for entry in badge_data.values()]

# Use or print the result
print(first_numbers)

JavaScript (Browser)

Using native fetch:

fetch('https://www.steamcardexchange.net/api/request.php?GetBadgePrices_Guest')
  .then(res => res.json())
  .then(data => {
    // Pull the first element from each array value
    const firstNumbers = Object.values(data).map(entry => entry[0]);
    console.log(firstNumbers);
  })
  .catch(err => console.error('Fetch error:', err));

JavaScript (Node.js)

Using axios (install first with npm install axios):

const axios = require('axios');

axios.get('https://www.steamcardexchange.net/api/request.php?GetBadgePrices_Guest')
  .then(res => {
    const firstNumbers = Object.values(res.data).map(entry => entry[0]);
    console.log(firstNumbers);
  })
  .catch(err => console.error('Request error:', err));

The key insight here is that you don't need to worry about the keys (those random-looking identifiers) — you just care about the array values, and grabbing their first element is all it takes.
