# Look up company profile by domain

`GET /v1/tech-lookup/companies/lookup`

## Request

- Base URL: `https://api.stackscan.com/api`
- URL: `https://api.stackscan.com/api/v1/tech-lookup/companies/lookup`
- Auth: HTTP bearer and API key in header `X-Tenant-Id`

Given a domain, returns the company behind it: name, industry, city,
country, address, LinkedIn URL, and how many technologies StackScan
tracks for that site. Deducts 1 Bulk Lookup Credit only when the
lookup finds data.

Rate limit: 500 requests per minute, counted per API token. Going over returns 429 with `error_code: rate_limited` and a `Retry-After` header in seconds. A 429 costs no credits. Traffic is also subject to a higher shared ceiling per network address, applied before authentication.

## Query parameters

- `domain` string, required
- `fresh` boolean

## Response `200`

Company profile for a domain (success). Returns Company Name, Industry, City, Country, Address, LinkedIn URL and total technologies tracked. No data: `{success: false, error: "No data available"}`. Deducts 1 Bulk Lookup Credit when success is true.
