Did you get the reschedule method to work? Looks like it's missing the g-recaptcha-response parameter. I was thinking of rewriting this method using selenium automation instead.
Also, do you notice requests being throttled and start getting empty array from DATE_URL? I ended up increasing SLEEP_TIME to 5 min - this gives me about 4 hours of consistent API calls and then again start getting empty values for a while.

Yes, I noticed it will get empty for a while. I am logging the output in my version, and it seems 60 SLEEP_TIME gives about 3 hours of consistent API calls. I think increasing to 5mins will be too conservative to get available space. Regarding the reschedule, it is not working now. I am trying to capture the POST data it was sending while rescheduling and then modify the reschedule method accordingly. But I do not have the chance to capture it at this moment. Do you have any suggestions?

When you are using the reschedule method, what response do you get?
I got <429 response> "a padding to disable MSIE and Chrome friendly error page" which is wierd because it's about too much requests and i only use POST once...
Also, for how long do you wait until you stop getting the empty arrays?

@PharAcc The thing is that I get this error on the first POST...and i wait 61 seconds between each call. In the end I used selinium to schedule an appointment so I managed to avoid the problem...

Hi @ADHDvir could you please share the solution you found for the scheduled , I'm still stuck at that point. thanks in advance

Hello, I tested it with the Colombia country code, I had an error with the get_time method but I fixed, I have not yet been able to test the reschedule method, there aren't available days, but I have a question, Does this code contemplates the scheduling of the consular appointment and the appointment of the ASC? I

@ADHDvir Could you kindly share the selenium solution?

You will always get the empty array, is a security configuration, but you can set on your code a sleep function and try later. I did that and I always try again after 1 hour.

I do the same, I think is the only way for keep the checking stable.

Any luck with the throttling? I've built a similar app on my side and getting the same issue, empty array after 48 requests. Then light ban for 5 hours

Do you know the period that 48 requests limit? Like 48 request within 1 hour?

I tried 5 locations every 10 minutes, also getting empty array after 4 hours. I'm not sure what the criteria is

Yes after getting the first empty array, I sleep for 1 hour until the next non-empty array (then it's back to checking every 5 minutes). But it still takes 5 hours to reset

I have a solution for that

Is the e-mail address' inbox still being monitored?
If not, could you please reply to mine?

Thanks.

Hey dresansol, did you figure out how to reschedule the ASC appointment? I haven't been able to do so :(

Guys, has anyone found out a way to deal with the throttling/ban?

Hey dresansol, did you figure out how to reschedule the ASC appointment? I haven't been able to do so :(

Here there is a repo with ASC appointment: https://github.com/Narias1999/visabot
Also, there is a repo with the original gist, here: https://github.com/uxDaniel/visa_rescheduler

The appointment, ASC and consular, should be scheduled with the UI because the post request doesn’t work. You have to write a js code for click on each list box and set the dates

I am also interested, emailed you.

I see that many people write here about the problem, so I will write here some points that will lead to a solution
In order to monitor the available dates, it is recommended to use accounts that have already had an interview meeting, even accounts that have already had an interview show available dates, if the account no longer shows available dates move to the next account, you need several accounts for this to monitor the dates,
The monitoring should be done in a separate window of the browser, and the central account for which you want to make an appointment in a separate window, if a queue is found, of course, continue the script in the window of the central account.
In addition, queues enter the system (except for very unusual cases) only during a round minute, for example 20:00 20:05 20:10 and so on... the mechanism that searches for available queues should only be activated during these minutes.
Someone needs to update the code here according to this data

Thanks for your code. It helps a lot.

Has anyone adjusted the code according to the data I wrote down?

Are you sure this was the reason? I've been executing my code for some friends and coincidentally they have been denied, but they have never told them anything related to the rescheduling process

Just wanted to come by and let you guys know that I had my visa cancelled last week by the US embassy, for running this script on my own, which apparently violates the Terms of use of the ais website.
Not sure how the heck they found out. I feel so miserable. Not worth it, mate. Good luck to y'all.

Was this canceled at the embassy before being approved or after it was approved some time after?

Hello Friends, I do not have any programming background. Could you please help me to run this script to get my appointment ?

its group of 3.

I am using a windows 11 laptop

hey guys, anyone has an idea about their rate limiting policy? I got 5 hour-bans twice and I dont want to risk it again. What is the optimal frequency and break-time to overcome this? Thanks in advance
