I think the biggest question is whether there's really a market for it, and companies willing to pay for it. It might take a while for Mint-like applications to come up, and solar companies to discover your API and start/consider using it. You might have to build something like that yourself; e.g. a Mint-like web app for all my utility accounts -- if anything to make the existence of pulese.energy more well-known. I'll admit that it's definitely very useful. Having a standard API to query usage data that works across various electric & gas companies is great. I personally might sign up for your API because I like having that sort of data. recently bought a WeMo Insight Switch to measure how much energy my desktop computer was using. But is there a larger market for it, besides nerds like myself? Are there B2B opportunities for your product; i.e. startups or large companies that need an API like pulse.energy? What you're trying to build reminds me of the Clever API for education: https://clever.com/ https://clever.com/ They provide a standard API to access student data that works across the heterogeneous systems that school districts. I've worked at an educational software company in the past, and the product I was building was critically reliant on Clever. Our product simply wouldn't work without it.
