Adzuna API vs Careerjet 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. Careerjet API is a job search API for Careerjet publishers who show Careerjet's job listings on their own sites.
The short answer
- Adzuna API: Building a job board or labour-market tool with an aggregated, multi-country job feed plus salary data.
- Careerjet API: Publishers who want to monetize traffic by showing Careerjet job listings to their own human visitors.
Side by side
| Adzuna API | Careerjet API | |
|---|---|---|
| Searches | Adzuna's aggregated job ads, queried per country via a two-letter code in the URL (docs examples use gb). | Careerjet's aggregated job listings, selected by a locale_code (language plus country, default en_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. | Jobs with title, company, date, description excerpt, locations, salary (currency, min, max, type) and url; plus type, hits, pages and response_time. |
| Before the first call | Register for an app_id and app_key, sent as query parameters on every call. | A Careerjet Publisher account and one API key per publisher website (Basic auth); every call must send the end user's IP address and user agent. |
| 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. | The url field example is a tracking link (https://jobviewtrack.com/v2/...), not a direct employer link. |
| 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 | No official server listed |
