Most software that touches companies needs the same few facts before anything else: what the company is called, what its logo looks like, where it lives online, and what kind of business it is. A full research profile is more than that job needs, and priced like it.
Company brand lookup is a small, cheap read for exactly those facts. Send one URL the company owns to GET /v1/entities/brand, and get back its brand kit:
- Names: the brand name (
Stripe), the legal name (Stripe, Inc.), and other names it goes by. - Logos: a standard logo and a square logo, with a flag that marks a letter monogram.
- Links: its current website and profile URLs, such as LinkedIn, X, Crunchbase, and GitHub, websites first.
- Tags and categories: tags such as
SaaSandPlatform, industries, main products, customer and revenue types, ownership, and industry codes such as NAICS and SIC, each with its primary value marked. - Its aVenture page, for when a person wants to read more.
Only current links and categories come back, and a field with no value is left out of the response.
curl -H "Authorization: Bearer $AUTH_TOKEN" \
"https://api.aventure.vc/v1/entities/brand?url=stripe.com"
The Company Brand Lookup guide documents every field, with examples in curl, JavaScript, Python, the CLI, and MCP.
Any URL the company owns works
The url can be the company's website or any current profile joined to it: LinkedIn, X, Crunchbase, GitHub, or its aVenture page. The lookup ignores the scheme, a leading www., and the case of the host, so stripe.com, https://www.stripe.com, and HTTP://STRIPE.COM all return Stripe. twitter.com counts as x.com, and LinkedIn country hosts count as linkedin.com.
When you already hold an aVenture slug or id, send that instead. Send exactly one of url, slug, or entityId.
The answer is exact, not a guess. The same input always returns the same company. If no company owns the URL, the call answers 404. If two companies share it, such as an investment firm and one of its funds, it answers 409 with both ids instead of picking one. When all you have is a company name, use Lookup, which weighs the evidence and tells you when it cannot decide.
What it costs
Each distinct company you look up counts as one brand view per calendar month (UTC). Looking up the same company again that month is free, whichever identifier you use. Brand views have their own allowance, separate from profile views:
| Plan | Brand views included each month |
|---|---|
| Essential (free) | 250 |
| AI Plus | 5,000 |
| AI Pro | 50,000 |
On AI Plus and AI Pro with additional usage turned on, each brand view past the allowance costs $0.001, or one dollar per thousand companies. That is a twenty-fifth of the price of a full company profile view.
What you can build with it
Logos and names in your own product. Show the right logo and name next to every customer, vendor, portfolio company, or prospect in a dashboard, a CRM, or a "trusted by" section. The logoSquare field is a storage path; call GET /v1/entities/{entityId}/logo for a full CDN URL you can put straight into an <img> tag.
Personalized sign-up and onboarding. When a new user signs up with a work email, send the domain and greet them with their company's name and logo, or route them by industry and customer type.
CRM and spreadsheet cleanup. Run each account's website through the lookup to fill in a consistent brand name, the legal name, and missing LinkedIn or X links. Two rows that return the same core.id are the same company. For a whole list at once, POST /v1/entities/lookup-matches answers one row per website, in input order.
Spend and transaction categorization. A card or bank export often names a counterparty by its domain. The brand kit turns that domain into a recognizable name and logo, and its industry codes give you a category for each line.
Contracts and vendor records. The legal name is the one that belongs on an invoice, a contract, or a vendor onboarding form, and it is often not the name on the website.
Lead routing and segmentation. Tags, industries, and revenue and customer types sort inbound companies into the right queue without a research step.
Link previews. When someone pastes a company URL into your chat app or notes tool, unfurl it into a card with the company's name, logo, and primary tag.
AI agents. An agent that only needs to know who a company is can call the brand lookup through the MCP server first, and read the full profile only when the task calls for funding, people, or news.
Recipes that start from a brand kit
The new Use Cases and Examples page in the aVenture docs starts with a brand kit from a website. Its other recipes pick up where the brand kit stops: matching a list of websites to companies, building a target list with filters, reading a funding history and the investors in a round, listing an investor's recent portfolio, tracing a founder's career, finding competitors, and monitoring news. Each recipe shows the API request, the aventure CLI command, and the MCP tool call side by side, with a real response.
From the CLI, the brand lookup is one command:
aventure entities brand get --url https://www.linkedin.com/company/stripe
Pick the right read
| You need | Use |
|---|---|
| Names, logos, links, and tags for a company you can identify by URL, slug, or id | GET /v1/entities/brand |
| The full record: research, funding, people, and news | GET /v1/entities/lookup-exact, which counts as a profile view |
| The company a bare name refers to | POST /v1/entities/lookup, described in Identify a company or person |
Try it
Brand lookup works on every plan, including the free plan's 250 brand views a month. Create an account, get an API key or sign in to the CLI, and send your first URL. The guide and the use cases page have everything else.
