API call in Flask

i am making the system where i can search the nse and nfo in search bar and can add it to the wishlist we want but while i wrote it in flask its not working please Guide me
Flask code -
from flask import Flask, render_template, request, jsonify
from kiteconnect import KiteConnect

app = Flask(__name__)

# Initialize Kite Connect API client
api_key = ''
api_secret = ''
kite = KiteConnect(api_key=api_key)
kite.set_access_token('') # Set your access token here

# Mock wishlist data (you can use a database instead)
wishlist = []

def dashboard():
return render_template('dashboard.html')

@app.route('/search', methods=['POST'])
def search_instruments():
query = request.form.get('query')
# Use Zerodha API to search instruments
instruments = kite.instruments('NSE') # Replace 'NSE' with 'NFO' for futures & options
search_results = [instrument for instrument in instruments if query.lower() in instrument['tradingsymbol'].lower()]
return jsonify(search_results)

@app.route('/add_to_wishlist', methods=['POST'])
def add_to_wishlist():
instrument_token = request.form.get('instrument_token')
# Check if the instrument is already in the wishlist
if instrument_token not in wishlist:
return jsonify({'message': 'Instrument added to wishlist'})

if __name__ == '__main__':

    Make sure your query variable is receiving valid instrument name from frontend code.
