free-apis-catalog skillA
free-apis-catalog is agent-read markdown (skill) from jamditis/claude-skills-journalism: Curated free APIs with verified free-tier limits. Use when suggesting APIs or finding free weather, news, finance, or sports data..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add jamditis/claude-skills-journalism/free-apis-catalog@git:20260818.3e0e3a8mdr add jamditis/claude-skills-journalism/free-apis-catalog@sha256:8efa266374ddd49ePin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
