HTTP error 429 when trying to buy token

[fm360]

After executing trade.py, whenever the bot tries to buy a coin it always receives an HTTP error 429

Was this ever resolved? I am getting same error on many occasions. On other occasions, it just fails to create associated token account.

[akegaviar]

Hey guys, 429 means you are getting rate limited. Check these:

• API error codes
• Solana specific limits

[Sahilkhurana]

Thanks. Looks like it is near impossible to run this in free (developer plan) to test proof of concept. Have tried 20+ times with each time getting rate limited.

[Firesampo]

Yeah, same problem here. I'm not sure how trying to make a purchase could make it already exceed the rate, I haven't had success to execute this even once. This happens every time, on the first coin I try to buy.

[akegaviar]

You can try the public RPC or other RPCs if you want to stay on the free plan. I'll also update the project with a bunch of features and requests and will include the ability to set the RPS pace in config.py,

(in the meantime you can do it yourself btw, just play around with the code and tune it to your needs like setting the RPS to match the one of the RPC node you use)
