Create an opensea bidding and selling tool using metamask api

I need a small program that will post bids on the Opensea NFT platform.

Tldr it takes ages to post several bids on Opensea and I want a program that can automate this.


https://docs.opensea.io/reference/api-overview

https://docs.metamask.io/guide/


What it would need to do:

- user connects the programme to their metamask account
- User selects a collection e.g. https://opensea.io/collection/decentraland
- The program would list all items in the collection along with the current winning bid (0 if none).
- The program would then put a bid slightly higher on all the items in the collection that a user selected (or select all)
- The amount to bid should be editable so a custom price can be selected.
- Users should be able to choose whether they bid in weth/dai/usdc
- Users should be able to choose the criteria of their bid (e.g. when it expires/amount/currency)
- The bot should then sign the transaction from a metamask wallet so the user doesn't have to

The purpose is to be able to make lots of offers and place lots of sells on NFTs without it having to take ages.

I would also like to see the finished code so that I can audit everything.
