pokeapi, using python, json, and inserting into postgresql table i cannot figure out why this won't work. please help i need to insert 100 records

I know something wrong with the cur.execute(sql, (defaulturl, )) part but I cannot figure out how to make this work. It starts listing the guy's names off but it won't insert them into the table pleas

#assign cursor
cur = conn.cursor()


#changed id to serial
sql = '''CREATE TABLE IF NOT EXISTS pokeapi(id SERIAL, url VARCHAR (2096) UNIQUE, body JSONB);'''

#print everything to the postgresql database
print(SQL)
cur.execute(sql)


defaulturl = "https://pokeapi.co/api/v2/pokemon/"
params = {'limit': 100}

for offset in range(1, 100, 1):
    params['offset'] = offset  # add new value to dict with `limit`
response = requests.get(defaulturl, params=params)

if response.status_code != 200:
    print(response.text)
else:
    sql = 'SELECT COUNT(body) FROM pokeapi;'
    data = response.json()
    for item in data['results']:
        print(item['name'])
    sql = 'INSERT INTO pokeapi (url, body) VALUES (%s, %s);'
    print(sql)
    cur.execute(sql (defaulturl, ))

print('Closing database connection...')
conn.commit()
cur.close()
