Side by side
| Greenhouse Job Board API | JSearch | |
|---|---|---|
| Searches | One employer's Greenhouse job board per call (by board_token); employer-direct, no cross-company search. | Aggregated postings via Google for Jobs, covering LinkedIn, Indeed, Glassdoor, ZipRecruiter and other public job sites. |
| Returns | JSON jobs with id, title, location.name, updated_at, absolute_url and, with content=true, the full description, departments and offices. | JSON jobs with job_id, job title, employer_name, job_publisher, job_city, job_country, job_min_salary, job_apply_link and apply_options; endpoints search-v2, job-details, company-job-salary, estimated-salary. |
| Before the first call | Nothing for GET: no authentication; you need the company's board_token. Submitting applications needs the company's API key. | An account and API key from the OpenWeb Ninja developer portal (also sold on RapidAPI). |
| Free | No key needed, and its pages state no price | Not stated on its pages |
| Acting on a result | absolute_url is the employer's own job post (the docs don't say where it is hosted). | job_apply_link is the primary apply link; apply_options lists links from other publishers, each flagged is_direct. |
| Coverage | Wherever the employer hires. | Not stated on its pages |
| MCP server | No official server listed | Official OpenWeb Ninja MCP server (npm @openwebninja/mcp-server) includes a jsearch tool: https://github.com/OpenWeb-Ninja/openwebninja-mcp |
