Company Registry Scraper — UK Companies House & Singapore ACRA

Official government APIs only — no scraping, no proxies, no proxy surcharges. From $2 per 1,000 companies. Search the registers, enrich UK records with officers, beneficial owners (PSC), and filing history, and get newly incorporated companies on a schedule. The legal, ban-proof alternative to scraped B2B databases.

Runs out of the box: no API key, no setup, for every mode. Singapore modes use open data; UK modes run on the actor's built-in Companies House key at the standard rate. Power users: add your own free Companies House key (2 minutes) and UK events are billed at the discounted BYOK rate.

What it does

Mode	Input	Output	Key needed
sg-search	keyword	Singapore companies (ACRA open data)	No
sg-lookup	UENs	Exact Singapore entity records	No
uk-search	keyword	UK companies matching the query	Free CH key
uk-enrich	company numbers	Full profile + officers + PSC + filing history	Free CH key
uk-new-incorporations	date range + SIC codes	Companies registered in that window	Free CH key

Getting the free Companies House key: register at developer.company-information.service.gov.uk, create an application, and copy the REST API key.

Fast Singapore name search. ACRA open data is sharded by the first letter of the entity name. sg-search checks the shard matching your query's first letter and returns in seconds when it fills your maxItems. For broad keyword queries (e.g. tech, logistics) where matches can start with any letter, enable sgFullSweep to merge results from all 27 shards (takes ~1–2 minutes, exhaustive).

The lead-gen workflow this was built for

Run uk-new-incorporations on a weekly schedule with your target SIC codes (e.g. 62012 software development, 56101 restaurants, 43390 fit-out contractors). Every run delivers the week's newly registered companies in your niche — names, addresses, incorporation dates — before they appear in any commercial database. Pipe into your CRM via the API, or enrich the interesting ones with uk-enrich to get current directors.

Pricing

Pay per event: company-found per search/monitoring result, company-enriched per full UK profile (officers and PSC included in the price). UK runs on the built-in key bill the -zero-setup variants (standard rate); bring your own free Companies House key for the discounted rate. Failed lookups are never charged. Set maxItems to cap spend.

Data sources & fair use

• UK: Companies House public API (Crown copyright, public register)
• Singapore: ACRA Information on Corporate Entities via data.gov.sg open data (updated by ACRA; registered-address granularity as published)

Both registries are public by law. Officer and PSC data are public-register records — use them lawfully (GDPR/PDPA apply to how you process them downstream). This actor is not affiliated with Companies House or ACRA.

Field coverage differs by registry: UK records include named officers, PSC, and filings (live API). Singapore records include entity details, status, SSIC codes, address, and officer count — the ACRA open dataset does not publish officer names.

Telemetry

Each run records one anonymous telemetry event to the developer's own storage: a salted hash of the caller account ID (never the raw ID), the run origin (e.g. web console vs API), and a timestamp. No inputs, results, or personal data are collected - this only measures adoption (distinct and returning users).
