Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

const url = "https://api.binance.com/api/v3/ticker/price?symbol=BTCUSDT";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

import requests

url = "https://api.binance.com/api/v3/ticker/price?symbol=BTCUSDT"
headers = {"X-API-Key": "YOUR_API_KEY"}

response = requests.get(url, headers=headers, timeout=30)
response.raise_for_status()
data = response.json()
print(data)

curl "https://api.binance.com/api/v3/ticker/price?symbol=BTCUSDT"

What Can You Build?

// Fetch current cryptocurrency prices
const headers = { 'X-Api-Key': 'YOUR_API_KEY' };
const response = await fetch(`https://github.com/binance/binance-spot-api-docs`, { headers });
const data = await response.json();
const coins = data.data || data.coins || data;
const top5 = Array.isArray(coins) ? coins.slice(0, 5) : [coins];
top5.forEach(coin => {
  console.log(`${coin.name || coin.symbol}: $${coin.price || coin.current_price}`);
});

// Track portfolio value with current prices
const headers = { 'X-Api-Key': 'YOUR_API_KEY' };
const holdings = { BTC: 0.5, ETH: 2.0 };
const response = await fetch(`https://github.com/binance/binance-spot-api-docs`, { headers });
const data = await response.json();
let total = 0;
Object.entries(holdings).forEach(([symbol, amount]) => {
  const price = data[symbol]?.usd || 0;
  total += price * amount;
  console.log(`${symbol}: ${amount} x $${price} = $${(price * amount).toFixed(2)}`);
});
console.log(`Total portfolio value: $${total.toFixed(2)}`);

// Monitor price and trigger alerts
const headers = { 'X-Api-Key': 'YOUR_API_KEY' };
const ALERT_THRESHOLD = 50000;
const response = await fetch(`https://github.com/binance/binance-spot-api-docs`, { headers });
const data = await response.json();
const price = data.price || data.bitcoin?.usd || 0;
console.log(`Current BTC price: $${price}`);
if (price > ALERT_THRESHOLD) {
  console.log('🚀 Price alert: BTC is above $' + ALERT_THRESHOLD);
}

How This API Fails

We deliberately sent this API a broken request and recorded exactly what came back on 2026-08-10. Knowing the shape of an error before you hit it makes error handling much easier to write.

{
  "code": -1100,
  "msg": "Illegal characters found in parameter 'symbol'; legal range is '^[\\w\\-._&&[^a-z]]{1,50}$'."
}

Common Errors & Troubleshooting
