Lever Postings API vs The Muse API for AI agents
Lever Postings API is Lever's REST API for a company's published job postings, designed to help that company build a job site. The Muse API is a public JSON API for job and company listings posted on The Muse.
The short answer
- Lever Postings API: Reading a known company's live openings, with direct apply links, from its own Lever account.
- The Muse API: A free, no-key way to pull The Muse's curated job listings with company context.
Side by side
| Lever Postings API | The Muse API | |
|---|---|---|
| Searches | One company's Lever postings per call (by site name); employer-direct; global and EU endpoints. | Jobs listed on The Muse, filterable by company, category, level and location (including flexible/remote). |
| Returns | JSON (or iframe/HTML) postings with id, text, categories, country, workplaceType, description, descriptionPlain, lists, salaryRange (optional), hostedUrl and applyUrl. | 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 to read postings: no key, only the company’s board name. Sending applications needs the company’s 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 | applyUrl is Lever's hosted application form for the employer's job. | 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 (EU-hosted accounts use api.eu.lever.co). | The location filter lists cities worldwide; no stated country coverage. |
| MCP server | No official server listed | No official server listed |
