Companies House API for the UK register: search by company name (current and former names), then pull the full register entry with status, SIC codes, registered office and accounts due dates, the officers current and resigned, and filing history with the filed PDF. 4 endpoints, 1 credit each, structured JSON.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add scavio-ai/skills/companies-house-api@sha256:96e66b193f67e889The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
