The Retro PGF API, hosted on https://vote.optimism.io/, facilitates a blockchain-based voting mechanism for the Optimism community. Leveraging the "Sign In With Ethereum" protocol, users can authenticate themselves and engage in ballot activities such as viewing, saving, and submitting their votes. Additionally, users can express their preferences by "liking" specific lists. For administrative purposes, there's a dedicated set of functions, protected by a unique API key, enabling the OP Foundation to download and manage all the submitted ballots in a structured CSV format.
