Side by side
| Greenhouse Job Board API | Coresignal | |
|---|---|---|
| Searches | One employer's Greenhouse job board per call (by board_token); employer-direct, no cross-company search. | Company websites, professional networks, ATS platforms and major job aggregators; 486M+ postings, 52M+ active, 195+ countries. |
| Returns | JSON jobs with id, title, location.name, updated_at, absolute_url and, with content=true, the full description, departments and offices. | Records with job_id, status, title, description, seniority, employment_type, company_name, company_domain, location, country/city, salary (min, max, currency), external_url and job_sources[].url. |
| Before the first call | Nothing for GET: no authentication; you need the company's board_token. Submitting applications needs the company's API key. | A Coresignal account and API key (trial available); queries use Elasticsearch DSL. |
| Free | No key needed, and its pages state no price | Trial with 2,000 free credits, no credit card required (1 credit per job posting record). |
| Paid | Not stated on its pages | Self-serve plans from $49 per month (Mini, 2,500 credits per month); datasets are custom-priced from $1,000. |
| Acting on a result | absolute_url is the employer's own job post (the docs don't say where it is hosted). | external_url is the job URL on the company's own site (not always filled); job_sources[].url gives each source posting. |
| Coverage | Wherever the employer hires. | 195+ countries. |
