Side by side
| Greenhouse Job Board API | The Muse API | |
|---|---|---|
| Searches | One employer's Greenhouse job board per call (by board_token); employer-direct, no cross-company search. | Jobs listed on The Muse, filterable by company, category, level and location (including flexible/remote). |
| Returns | JSON jobs with id, title, location.name, updated_at, absolute_url and, with content=true, the full description, departments and offices. | JSON pages of 20 results; each job has name, contents (description), publication_date, locations, levels, categories, company and refs.landing_page. |
| Before the first call | Nothing for GET: no authentication; you need the company's board_token. Submitting applications needs the company's API key. | Nothing for testing; an api_key from registration is required for any use beyond testing. |
| Free | No key needed, and its pages state no price | 500 requests per hour without a key; 3,600 per hour with a registered key. No price is stated. |
| Acting on a result | absolute_url is the employer's own job post (the docs don't say where it is hosted). | refs.landing_page points to the job page on themuse.com. |
| Limits on keeping or showing results | Not stated on its pages | Content shown via the API must link back to The Muse; on termination you must destroy stored Muse Content (terms last modified 7/25/2015). |
| Coverage | Wherever the employer hires. | The location filter lists cities worldwide; no stated country coverage. |
| MCP server | No official server listed | No official server listed |
