Max retries exceeded

When I call comtradeapicall.getFinalData, I will get HTTPSConnectionPool(host='comtradeapi.un.org', port=443): Max retries exceeded with url error. Is there any limitation of getFinalData?

Gotcha,

Thanks!

Following up on this to clarify whether I understand the new API restrictions correctly.

When making the following query (see below), I would expect to receive a dataframe with at most 97 rows because there are at most 97 2-digit HS codes in a specific year. However, I get Error code: 429 Error message: Rate limit is exceeded. Try again in 2 seconds. If the restriction is that we get a max of 500 entries/rows per query and we're still limited to 100 queries/hour with the free tier, then @uncomtrade help me understand why I keep running into this rate limit exceeded error. I have not exceeded my 100 queries/hour limit.

mydf = comtrade.previewFinalData(
  typeCode='C', 
  freqCode='A', 
  clCode='HS', 
  period='2002',
  reporterCode='842',  #USA
  cmdCode='AG2',
  flowCode='M', 
  partnerCode='156', #China
  partner2Code=None,
  customsCode=None, 
  motCode=None, 
  maxRecords=500, 
  format_output='JSON',
  aggregateBy=None, 
  breakdownMode='classic', 
  countOnly=None, 
  includeDesc=True
)

I guess the service is currently undergoing maintenance. I have conducted some tests, and the requests that used to work fine are now giving the same error as you mentioned.

Waiting for the official team to resolve this issue~😀

@uncomtrade do you happen to know when this issue will be resolved?

[senn117]

You can check if the search page on the official website can successfully fulfill your query (similar to calling an API).
[https://comtradeplus.un.org/TradeFlow?Frequency=M&Flows=X&CommodityCodes=0201&Partners=0&Reporters=124&period=201509&AggregateBy=none&BreakdownMode=plus]

If you're in a hurry, you can try contacting them through their official email or Twitter. I noticed they are quite active on Twitter, so you can give it a try. 😁

Thanks @senn117. I sent them an email; hoping they'll resolve this sooner rather than later since it seems to be affecting their web interface as well.

[senn117]

You're welcome @najuzilu 😀. I also look forward to the issue being fixed smoothly by the official team. I use their API services to query data every month, which is very convenient.

It looks like the API is now working.
