A name or number → the right registered company, ranked by confidence.

Companies House search, cleaned and confidence-scored. Every hit carries a 0–1 match score so you can auto-pick the right company instead of eyeballing a noisy list.

Companies House search returns an unranked list where "Smith Consulting" surfaces forty near-misses in arbitrary order — fine for a human eyeballing results, useless for software that has to pick one. This endpoint adds the missing layer: every hit carries a 0–1 match confidence built from two-way name analysis, so exact matches rank strictly above supersets and your code can auto-select safely. Company-level only, by design — it never touches officer or PSC personal data.
