So as the title says, im having this error since a few weeks ago, i tried in computer and in a phone but it always appears that error of "You made too many requests", it says try it later but i think that 1 week or almost 2 are more than enough.

I sold 2 cards that gave me 0.25 cents so maybe that haves something to do with this error? because after that everything was okay

You hit an API quota limit. This quota limit is IPv4 based. If restarting your router doesn't help, you'll have to wait it out.

IPv4 addresses are not unique anymore. As there are more humans (8 billion) than IPv4 addresses (4.2 billion), ISPs have chosen to route users together on an identical IPv4 address. This technique is known as CGNAT.[en.wikipedia.org]

For Valve's inventory and community market API this bundled together group of users using CGNAT or Dual Stack Lite looks like a single user.

If you waited several days to weeks, your only recourse is getting a public IPv4 address. It doesn't matter whether this one is static or dynamic. Ask your ISP on how to obtain one.

If you already have a public also known as dedicated IPv4 address, you should stop spamming inventory actions.
