Adzuna API vs The Muse API for AI agents
Adzuna API is a REST API from the Adzuna job search engine for searching its job ads plus salary and labour-market data. The Muse API is a public JSON API for job and company listings posted on The Muse.
The short answer
- Adzuna API: Building a job board or labour-market tool with an aggregated, multi-country job feed plus salary data.
- The Muse API: A free, no-key way to pull The Muse's curated job listings with company context.
Side by side
| Adzuna API | The Muse API | |
|---|---|---|
| Searches | Adzuna's aggregated job ads, queried per country via a two-letter code in the URL (docs examples use gb). | Jobs listed on The Muse, filterable by company, category, level and location (including flexible/remote). |
| Returns | JSON results with id, title, a description snippet, company.display_name, location, category, salary_min/salary_max, salary_is_predicted, contract_type, created, latitude/longitude and redirect_url. | 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 | Register for an app_id and app_key, sent as query parameters on every call. | Nothing for testing; an api_key from registration is required for any use beyond testing. |
| Free | Default limits of 25 hits per minute, 250 per day, 1,000 per week and 2,500 per month; commercial use is permitted subject to a 14-day trial. | 500 requests per hour without a key; 3,600 per hour with a registered key. No price is stated. |
| Acting on a result | redirect_url; the documented examples point to adzuna.co.uk/jobs/land/ad/... (through Adzuna), not straight to the employer. | refs.landing_page points to the job page on themuse.com. |
| Limits on keeping or showing results | Each displayed ad must carry an 'Adzuna' label at least 116x23 px, linked to Adzuna; on termination all Adzuna data must be removed; after the trial a licence agreement may be required. | 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 | Not stated on its pages | The location filter lists cities worldwide; no stated country coverage. |
| MCP server | No official server listed | No official server listed |
