LinkedIn Jobs vs Adzuna API for AI agents
LinkedIn documents no public job search API; its jobs API is for approved partners (ATS systems, job distributors) to post jobs to LinkedIn, and it is closed to new partners. Adzuna API is a REST API from the Adzuna job search engine for searching its job ads plus salary and labour-market data.
The short answer
- LinkedIn Jobs: ATS vendors and job distributors that already partner with LinkedIn and need to publish jobs to it; not for finding jobs.
- Adzuna API: Building a job board or labour-market tool with an aggregated, multi-country job feed plus salary data.
Side by side
| LinkedIn Jobs | Adzuna API | |
|---|---|---|
| Searches | Not a search API: it posts jobs into LinkedIn on behalf of customers. | Adzuna's aggregated job ads, queried per country via a two-letter code in the URL (docs examples use gb). |
| 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. |
| Before the first call | LinkedIn approval, a signed API agreement with data restrictions, and Talent Solutions partner status; currently not accepting new partnerships (points to Apply Connect instead). | Register for an app_id and app_key, sent as query parameters on every call. |
| 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. |
| Acting on a result | – | redirect_url; the documented examples point to adzuna.co.uk/jobs/land/ad/... (through Adzuna), not straight to the employer. |
| Limits on keeping or showing results | LinkedIn API Terms forbid caching or storing Content except as needed to run your application, and bar content obtained by scraping or crawling outside the APIs. | 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. |
| MCP server | – | No official server listed |
