Adzuna API vs Jooble 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. Jooble API is a REST API that lets site owners take Jooble job search results and show them on their own website.
The short answer
- Adzuna API: Building a job board or labour-market tool with an aggregated, multi-country job feed plus salary data.
- Jooble API: Embedding Jooble search results in your own site design for a single country.
Side by side
| Adzuna API | Jooble API | |
|---|---|---|
| Searches | Adzuna's aggregated job ads, queried per country via a two-letter code in the URL (docs examples use gb). | Jooble's aggregated job search, one country per key (a jooble.org key covers US listings; other countries use their regional domain). |
| 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 with totalCount and jobs, each with id, title, location, snippet, salary, source, type, link, company and updated. |
| Before the first call | Register for an app_id and app_key, sent as query parameters on every call. | Fill in a form (name, position, email, website, phone) to get a key; each country domain needs its own key, sent in the URL path of a POST. |
| 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. | The free plan has a lifetime limit of 500 requests per key (not monthly). |
| Acting on a result | redirect_url; the documented examples point to adzuna.co.uk/jobs/land/ad/... (through Adzuna), not straight to the employer. | link is the job posting on Jooble. |
| 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 |
| Coverage | Not stated on its pages | Per-country keys via Jooble's regional domains (e.g. jooble.org for the US, uk.jooble.org, de.jooble.org). |
| MCP server | No official server listed | No official server listed |
