MATIC limits messed up?

API Spot/Margin API
1

MATIC appears to be missing part of its ‘limits’ information in the API. I think this used to work fine. (the missing bit is in bold)

for s in [‘BTC’, ‘ETH’, ‘BNB’, ‘RAY’, ‘MATIC’]:
print(s, ‘:’, a[s + ‘/USDT’][‘limits’])

BTC : {‘amount’: {‘min’: 1e-05, ‘max’: 9000.0}, ‘price’: {‘min’: 0.01, ‘max’: 1000000.0}, ‘cost’: {‘min’: 10.0, ‘max’: None}, ‘market’: {‘min’: 0.0, ‘max’: 188.56935531}}
ETH : {‘amount’: {‘min’: 0.0001, ‘max’: 9000.0}, ‘price’: {‘min’: 0.01, ‘max’: 1000000.0}, ‘cost’: {‘min’: 10.0, ‘max’: None}, ‘market’: {‘min’: 0.0, ‘max’: 3217.68945562}}
BNB : {‘amount’: {‘min’: 0.001, ‘max’: 900000.0}, ‘price’: {‘min’: 0.1, ‘max’: 100000.0}, ‘cost’: {‘min’: 10.0, ‘max’: None}, ‘market’: {‘min’: 0.0, ‘max’: 13475.17657152}}
RAY : {‘amount’: {‘min’: 0.1, ‘max’: 9222449.0}, ‘price’: {‘min’: 0.0001, ‘max’: 10000.0}, ‘cost’: {‘min’: 10.0, ‘max’: None}, ‘market’: {‘min’: 0.0, ‘max’: 254569.23875}}
MATIC : {‘amount’: {‘min’: 0.1, ‘max’: 9000000.0}, ‘price’: {‘min’: 0.0001, ‘max’: 1000.0}, ‘cost’: {‘min’: None, ‘max’: None}, ‘market’: {‘min’: 0.0, ‘max’: 2196458.97}}

Looking at your post I can’t seem to see any part of it which is bold? Can you please specify exactly what the issue being faced is?

In fact the issue is deeper than that. There are 10 assets that are busted this way.

import requests
import json
import traceback

url = f"https://api.binance.com/api/v3/exchangeInfo"
data = json.loads(requests.get(url).text)
for symbol_idx in range(len(data['symbols'])):
    try:
        min_notional = data['symbols'][symbol_idx]['filters'][2]['minNotional']
    except Exception as e:
        print(data['symbols'][symbol_idx]['symbol'], traceback.format_exc())
        min_notional = data['symbols'][symbol_idx]['filters'][6]['minNotional']  # This works for these ones
