From the company's own job postings. Each posting is read for the technologies it names, and every company and technology pair is graded: confirmed when two independent checks agree on C# in at least one posting, likely when it is a stated requirement or appears in two separate postings. A single passing mention is not counted here. It is evidence of a team working with C#, not a purchase record. ## Reproduce ```bash curl -X POST https://api.jobspipe.dev/v1/companies/search -H "Authorization: Bearer $JOBSPIPE_API_KEY" -H "Content-Type: application/json" -d '{"company_technology_slug_or":["c#"],"tier_min":"confirmed","company_country_code_or":["KR"],"limit":25}' ``` --- Try it with no key: `curl -d '{"limit":3}' https://api.jobspipe.dev/v1/sandbox/jobs/search`.
