Company search API, answered.
More details in the API documentation.
What is a company search API?
A company search API finds businesses that match a description and returns them as structured data. Send a query such as “solar startups in California that raised a Series B” and get up to 10 companies per request, each with its domain, industries, headquarters, headcount, and funding.
How much does the Company Search API cost?
Each search returns up to 10 companies for 2 credits, and searches with no matches are free. The free plan includes 1,000 credits every month, enough for 500 searches. Paid plans start at $20 a month for 10,000 credits.
Is there a free company search API?
Yes. The free plan includes 1,000 credits a month with no credit card, which covers 500 searches and up to 5,000 companies. You can also try the free Company Search tool without signing up.
What does each result include?
The name, domain, description, industries, founding year, headquarters, headcount as an exact count or a range, and funding with the current stage, total raised, latest round, and known rounds. Organization type, operating status, stock symbols, and an estimated revenue range are included when available.
How do the country and headcount filters work?
filters.countries limits headquarters to two-letter country codes such as US or DE. employees_min and employees_max set a headcount range and include companies whose reported range overlaps it, with exact matches preferred.
How does funding search work?
funding.stage is the company’s current stage, while latest_round and rounds describe its history. Ask for “Series B companies” to match the current stage, or “companies that raised a Series B” to match a past round.
How do I get more than 10 results?
Pass next_cursor from the response back as cursor, with the same query and filters, to fetch the next page. Stop when next_cursor is null. There is no limit parameter.
Which languages can I use?
Any language that can send an HTTPS request. POST to https://api.context.dev/v1/company/search with your API key in the Authorization header. The examples on this page cover TypeScript, Python, Ruby, PHP, Go, and cURL.
How is Company Search different from Auto-complete Brand?
Auto-complete Brand matches a company name or domain as someone types. Company Search finds companies that fit a description. Use Retrieve Brand for a company’s logos, colors, and full brand profile.

Describe the market and get structured company data back. The same API key works for people search, brand data, and scraping.
