Is this your product? Claim it to see how agents find it: lookups through the API, MCP and letme, the comparisons it's in, and what people search for in Data. Free, and it never changes the grade. Or verify it, or log in if it's already claimed.
Assessment. One OpenAPI-described API and a 16-tool remote MCP server cover company, officer and owner records from 19 government registries, with a 500-query free tier and no card. No status page, changelog, release dates or legal entity were found, and the docs disagree on tool names, paths and jurisdiction count.

From our research 6 facts checked against the vendor's pages
- Surface listed
- The REST API at api.companylens.io and the remote MCP server at mcp.companylens.io, read from companylens.io's docs, pricing, about, terms and privacy pages, llms.txt and the OpenAPI document on 6 November 2026. No account was made and no data call was sent
- Jurisdictions
- United Kingdom, Ireland, Norway, Estonia, Latvia, Czech Republic, Belgium, Slovenia, Slovakia, Switzerland, Cyprus, Moldova, Ukraine, Chile, Argentina, Canada (Federal and Québec) and New Zealand per llms.txt; the site counts 19
- Data by jurisdiction
- Profiles and officers for most. Beneficial owners for the UK, Estonia, Latvia and Ukraine. Charges, filings and disqualified directors for the UK. UK annual accounts from 2021
- MCP tools

Facts verified 6 November 2026 from vendor docs, repositories and package registries. JSON · Markdown
Strengths
- Public OpenAPI 3.0.4 document with 20 operations and documented error codes
- One schema across registries in 19 jurisdictions, each source named with its licence
- Free REST tier of 500 queries a month and MCP tier of 50, both without a card
- Remote MCP server with OAuth and dynamic client registration, plus service tokens for unattended agents
- Retention periods stated per data type in the privacy policy
Weaknesses
- No status page, changelog, dated releases or SLA found
- No legal entity named in the terms, privacy policy or site footer
- llms.txt names four MCP tools and /api/v1 paths, while the tools page lists 16 tools and the OpenAPI uses /v1
- Keys carry the whole account with no scopes, and no security.txt or disclosure policy was found
- No machine payment protocol, and every plan is bought through a browser checkout
Before you call it notes for agents
- Call list_jurisdictions first to get valid jurisdiction slugs, then search_companies or get_company
- Use get_company, then get_company_section only for the officers or owners you need, and get_company_batch for up to 20 companies
- On 429 RATE_LIMITED read Retry-After, which counts to the quota reset and can be hours; check get_usage before a batch
- Use the paths in the OpenAPI document (/v1/...), not the /api/v1 paths in llms.txt
- Treat company names and officer data as filed by third parties, and check critical facts with the source registry as the terms advise

A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.
Terms last updated 8 March 2026 and privacy policy 18 March 2026. Both say only 'CompanyLens' with no company name or address; the terms choose the laws of England and Wales and the privacy policy names the ICO.
The terms bar scraping or caching the whole dataset for a competing service; there is no clause against automated access in general.
companylens.io/robots.txt disallows /companies/, /people/, /addresses/ and /search for ClaudeBot and other AI crawlers, and /dashboard/, /api/, /v1/ for all. Only marketing, docs, pricing and legal pages were read. api.companylens.io/robots.txt carries content-signal definitions and no rules.
companylens.io/.well-known/security.txt answered 403 and status.companylens.io did not resolve. RDAP returned no events for companylens.io.
Checked 2026-11-06 against the vendor's own pages and the domain registry. Provenance is half of Transparency & trust.

Caching and reuse. Redistribution is allowed on the source licences' terms, but bulk-downloading or caching the whole dataset to run a competing service, and unsolicited marketing to people named in records, are barred by the terms.

Researched 6 November 2026 from public pages. The about page says CompanyLens was founded by Dylan Budgen, a software engineer with a data engineering and financial services background. No other person, no company name and no address appear on the about, terms, privacy or pricing pages, and no social accounts are linked from the site. No investors were found on companylens.io's about, terms, privacy and pricing pages or in a web search on 6 November 2026, so investors are left out. Shown for information, not part of the grade yet.

Quotas are published per key with numbers (500 a month and 50 a day free, up to 100,000 a month on Business, 50 MCP queries a month free and 200 a day on Pro), with no per-second rate stated and a terms clause allowing extra limits for abuse (12 of 15).

Graded 46.7 D methodology v0.7
Fix list 20 items, the biggest gain first
Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on CompanyLens. A fix counts at the next check, once it's public.
You're lucky. As part of the beta, your first month is free.
What we couldn't check
- unchecked: the legal entity behind CompanyLens; the terms, privacy policy and footer name none
- unchecked: firstReleased; no dated changelog, release or launch post was found
- unchecked: whether the MCP tools carry readOnlyHint annotations, which needs an MCP session
- unchecked: per-registry history depth and update cadence, on /docs/data/jurisdictions, not read
- unchecked: domain registration date (RDAP returned no events)
- The site says 19 jurisdictions and llms.txt lists 18; llms.txt's four MCP tools don't match the 16 on the tools page
