Adzuna API vs JSearch 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. JSearch is a commercial job search API that returns live job postings and salary estimates gathered from Google for Jobs.
The short answer
- Adzuna API: Building a job board or labour-market tool with an aggregated, multi-country job feed plus salary data.
- JSearch: Broad, Google-for-Jobs-style job search across many boards from one API.
Side by side
| Adzuna API | JSearch | |
|---|---|---|
| Searches | Adzuna's aggregated job ads, queried per country via a two-letter code in the URL (docs examples use gb). | Aggregated postings via Google for Jobs, covering LinkedIn, Indeed, Glassdoor, ZipRecruiter and other public job sites. |
| 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 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 | Register for an app_id and app_key, sent as query parameters on every call. | An account and API key from the OpenWeb Ninja developer portal (also sold on RapidAPI). |
| 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. | Not stated on its pages |
| Acting on a result | redirect_url; the documented examples point to adzuna.co.uk/jobs/land/ad/... (through Adzuna), not straight to the employer. | job_apply_link is the primary apply link; apply_options lists links from other publishers, each flagged is_direct. |
| 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. | 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 |
