Are there any web wallets around with open APIs? For a long while, blockchain.info offered a web wallet with a convenient web API, but it recently turned out that it now requires an installation to function. I'm wondering - are there any other reputable web wallets out there for developers, with open APIs for sending / receiving coins that don't require an installation of any sorts?
Yes, block.io is a good alternative with full wallet functions. No requirement for NPM or a VPS.
