429 Error on Starter Tier Despite Rate Limiting

Hi Render Community,

I’m encountering a 429 Too Many Requests error on the Starter tier, despite implementing rate limiting and sleep intervals in my FastAPI application. Interestingly, the same setup works fine on the Free tier.

Could there be something specific to the Starter tier causing this issue? Any guidance would be appreciated.

Thanks

Hi Mohsin,

One possibility is that since the Starter tier gets you more CPU time, you’re able to hit a higher rate of requests than you do with the Free tier.

You should just adjust your rate limiting until the 429s stop.

Matt
