Diff Checker API

br0ski777/diff-checker-x402

A straightforward diff utility that compares two text inputs and returns line-by-line changes showing additions, deletions, and unchanged content. It runs as a hosted service over SSE transport and includes x402 micropayment integration, meaning you'll pay per use rather than a flat subscription. The repository is fairly minimal with no readme or detailed documentation visible, so you're working with basic diff functionality without much insight into advanced features or configuration options. Reach for this when you need programmatic text comparison in Claude and don't want to run a local server, though the payment model means costs could add up with heavy use.
