Hello i am developing some kind of marketplace i dont want to download whole blockchhain on my pc even in prune mode
anybody know any website which provide username password and api url so i can configure it with my application for testing perpose

I couldn't find any but check this one https://chainquery.com/

Or I think if you don't have enough space in your PC why not use a cloud service or VPS hosting where you can install a full node and start your project there?

Aws is offering a free trial for 1 year I think and Google Cloud also offers $100 free credit that you can use to start a remote desktop.

already used trail funds of google cloud and aws also digitaloccean and many other compnies .

if this kind of service doesnt exist i should start one becuase every developer dont have much diskspace and bandwidth .

a simple question can we add multiple username in bitcoin config ?

to access rpc and assigm them seprate wallets

It cost me less than $0.50 (https://bitcointalk.org/index.php?topic=5434679.msg61714795#msg61714795) to download and prune the full Bitcoin blockchain on a cheap pay-per-hour VPS. If you're developing a marketplace, I don't think you should rely on third parties for your data lookups.
If it's for testing, use testnet. It has a much smaller blockchain.

I sometimes use getblocks... They have a free api that's more than sufficient for normal day-to-day implementations. There is a limit on the amount of daily calls tough.

getblock.io (i'm not affiliated with them)

QuickNode and GetBlock are two options. Also you can rent a server from any reputable vendor, install Bitcoin Core on it, and then add your own username and password to it so that once the blockchain is completely synced on that server, you can query it privately.

It is not recommended to share RPC credentials because this will lead to the server getting DoS'ed by bad guys. (denial of service attack)

So you want to develop a web wallet where users don't need to download a full blockchain with a separate wallet and want to manage them on a pooled single wallet with your node?

If it's for the RPC server then no it doesn't support multiple users you will need to develop software where you can track sent/received to each user and make sure that they can only spend BTC that belongs to their wallet address.
Or else you will need separate full nodes for each user but this will require more resources.

Since you mentioned you are planning to develop a marketplace why not use BTCpayserver for your users? It has a feature called "BTCPay Server Wallet".
You can find more details about this here https://docs.btcpayserver.org/Wallet/

Don't worry about hosting BTCpayserver you can run it with your PC and it requires a node but you don't need to download the entire blockchain, the minimum pruned is around 5GB according to their documentation.

Yes we are using btcpayserver  its give wide options of integration of coins

Yes to the testnet local.
If you don't want to do testnet any of the BTC clone / shitcoins wallets should be easy enough to test on so long as their codebase is close to current core.

Keep in mind that if you are dealing with peoples money you really should be running your own server, since if the service you are using has an issue then YOU have an issue.
