**Describe the bug** I'm trying to sign a message with the `wallet-selector` and getting a 404 on the NEAR Wallet.  **To Reproduce**...

How should we approach testing to improve our test coverage on Mintbase.js?

As started here: https://github.com/Mintbase/mintbase-js/pull/106 We should spend some time to finish the implementation.

Let's simplify the API by reducing the amount of methods that can for example list tokens in the marketplace to one. Similarly to how `transfer` works.

- Create endpoint for offers on `mainnet` and `testnet` - Integrate on [API](https://github.com/Mintbase/mintbase-js/blob/main/src/api.ts)

Assure fetch by id, returns a unique result and not an array.
