Experiencing intermittent 429 errors when querying AeroAPI endpoints

FlightAware AeroAPI
1

Hello everyone,

I am facing intermittent 429 errors while querying AeroAPI endpoints in my application. These errors occur continuously , and I am not sure about the root cause. As far as I understand, a 429 error indicates that I’m hitting a rate limit, but I’m not consistently exceeding the rate limits specified in the AeroAPI documentation.

I primarily query the INSERT_ENDPOINT_HERE endpoint for flight data.
According to the documentation, the rate limit for my subscription level is X requests per minute, and I’m well within this limit based on my usage logs.
I make requests at regular intervals of Y seconds to ensure I’m not exceeding the rate limit.

Even after these precautions, I still get 429 errors occasionally. I have referred AeroAPI Developer Portal - FlightAware guide but haven’t found specific troubleshooting steps for intermittent 429 errors.

Are there any tips on how to handle rate limits more effectively?

Any guidance or insights would be greatly appreciated!

Thank you. :slightly_smiling_face:

If your usage is very close to the rate limit, then you might still occasionally hit the error message depending on when the minute interval roll-over occurs on the server side. The rate limiting is enforced by our network-layer partner that is providing an internet-facing front to our API backend and is mostly beyond our control.
