Chris Troutner -

Current Work:
*bch-api is my personal fork of It’s the REST API I’m focusing on, but the pay-to-play scheme could be abstracted for any REST API, and it is my hope that other developers will copy this business model to create pay-to-play REST APIs for all sorts of services in the BCH space.
*Code repository:
*jwt-bch-frontend is a Gatsby front end web app for interacting with the jwt-bch-api back end. A live demo can be found at This lets people create an account, login, get a free-tier JWT access token, or pay for pro-tier access token for unlocking increased rate limits to bch-api. Code repository:
*jwt-bch-lib is an npm library to allow apps to interact with jwt-bch-api back end. The goal is to allow apps to automate their handling of JWT tokens, rate-limits, and access to bch-api. All the ‘account owner’ needs to do is make sure their account is topped up with BCH. This library will allow an app to automatically renew its JWT token or increase rate limits on-the-fly. It’s purpose is to make payment for access efficient and automated. Code repository:
