API Error Fix Guide

Issue: "API Error: Failed to fetch"

This happens when the Groq API request fails. Here's how to diagnose and fix:

Step 1: Verify Your Groq API Keys

Your current keys in .env look suspicious (they appear to be test/placeholder keys).

Get real Groq API keys:

1. Go to: https://console.groq.com
2. Sign up or log in
3. Create an API key
4. Copy it and paste into .env:

GROQ_API_KEY=gsk_xxxxxxxxxxxxxxxxxxxxxxxxxxxx
GROQ_API_KEY2=gsk_yyyyyyyyyyyyyyyyyyyyyyyyyyyyy

Step 2: Test Your Setup

Start your server first:

npm start

Then test your API keys using the new test endpoint:

# Test Groq API keys
curl -X POST http://localhost:3000/test/groq-keys

# Test Binance connection  
curl -X POST http://localhost:3000/test/binance

# Test full analysis flow
curl -X POST http://localhost:3000/test/full-analysis \
  -H "Content-Type: application/json" \
  -d '{"symbol":"BTCUSDT","question":"Is BTC bullish?"}'

Step 3: Check Logs

Look for errors in the server logs. The test endpoint will show:

• ✓ VALID if the API key works
• ✗ INVALID if there's an auth issue
• ERROR if there's a network issue

Common Issues & Fixes

"INVALID ✗" - Auth Error

• Your Groq API key is wrong/expired
• Fix: Get a new key from https://console.groq.com

"ERROR" - Network Issue

• Can't reach Groq servers or Binance API
• Fix: Check your internet connection, try ping api.groq.com

"Request timeout"

• Binance API is slow or not responding
• Fix: Try again, or increase timeout in src/services/binance.js (currently 15s)

Step 4: Verify in UI

1. Open http://localhost:3000
2. Type your question: "Is BTC bullish?"
3. If it works: You'll see an analysis ✓
4. If it fails: You'll see a detailed error message
