companies-house-cli（companies house CLI 搜索）

companies-house-cli

Use ch for UK Companies House data: company search, profiles, officers, filings, PSC, charges, and insolvency.

Setup

• npm install -g @shan8851/companies-house-cli
• Get a free API key: https://developer.company-information.service.gov.uk/
• export COMPANIES_HOUSE_API_KEY=your_key or add it to a local .env

Search

• By name: ch search "Revolut"
• With restrictions: ch search "Revolut" --restrictions active-companies
• Fetch all pages: ch search "Revolut" --all
• JSON in canonical style: ch search "Revolut" --json

Company Profile

• By number: ch info 09215862
• Force text: ch info 09215862 --text
• Short numbers auto-pad: ch info 9215862 becomes 09215862

Officers

• List directors/secretaries: ch officers 09215862
• All officers: ch officers 09215862 --all
• Order by: ch officers 09215862 --order-by appointed_on

Filings

• Filing history: ch filings 09215862
• Filter by type: ch filings 09215862 --type accounts
• Include document download links: ch filings 09215862 --type accounts --include-links
• All filings: ch filings 09215862 --all

PSC (Beneficial Owners)

• List PSC records: ch psc 09215862
• All records: ch psc 09215862 --all

Search Person

• Find a person across UK companies: ch search-person "Nik Storonsky"
• Limit enrichment fan-out: ch search-person "Nik Storonsky" --match-limit 5
• Fetch all search pages: ch search-person "Nik Storonsky" --all

Charges

• List company charges: ch charges 09215862
• All charges: ch charges 09215862 --all

Insolvency

• Check insolvency history: ch insolvency 09215862
• Returns empty result cleanly if no history exists (not an error)

Pagination

• List commands support: --items-per-page <n>, --start-index <n>, --all
• --all fetches every page automatically
• --all and non-zero --start-index cannot be combined

Output

• Defaults to text in a TTY and JSON when piped
• Canonical usage is subcommand-local flags: ch search "Revolut" --json, ch info 09215862 --text
• Root compatibility aliases still work: ch --json search "Revolut", ch --text info 09215862
• Success envelope: { ok, schemaVersion, command, requestedAt, data }
• Error envelope: { ok, schemaVersion, command, requestedAt, error }
• Command metadata now lives under data.input and data.pagination
• Disable colour: ch --no-color search "Revolut"

Agent Notes

• JSON mode writes handled errors to stdout, not stderr
• Error payloads include code, message, and retryable
• Exit codes are explicit:

- 0 success - 2 bad input or not found - 3 auth, upstream, or rate-limit failures - 4 internal failures

• Update any existing parsers that expected top-level input or pagination; those now live under data

Notes

• API key required (free, instant signup at Companies House developer portal)
• Auth is HTTP Basic (key as username, blank password)
• Rate limit: 600 requests per 5 minutes
• Company numbers are automatically zero-padded to 8 digits
• search-person fans out appointment requests for each match — use --match-limit on broad names to control API usage
• --include-links on filings derives document content URLs for direct PDF download
