Lever Postings API vs Adzuna API for AI agents
Lever Postings API is Lever's REST API for a company's published job postings, designed to help that company build a job site. 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
- Lever Postings API: Reading a known company's live openings, with direct apply links, from its own Lever account.
- Adzuna API: Building a job board or labour-market tool with an aggregated, multi-country job feed plus salary data.
Side by side
| Lever Postings API | Adzuna API | |
|---|---|---|
| Searches | One company's Lever postings per call (by site name); employer-direct; global and EU endpoints. | Adzuna's aggregated job ads, queried per country via a two-letter code in the URL (docs examples use gb). |
| Returns | JSON (or iframe/HTML) postings with id, text, categories, country, workplaceType, description, descriptionPlain, lists, salaryRange (optional), hostedUrl and applyUrl. | 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 | Nothing to read postings: no key, only the company’s board name. Sending applications needs the company’s key. | Register for an app_id and app_key, sent as query parameters on every call. |
| Free | No key needed, and its pages state no price | 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 | applyUrl is Lever's hosted application form for the employer's job. | 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 | Not stated on its pages | 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. |
| Coverage | Wherever the employer hires (EU-hosted accounts use api.eu.lever.co). | Not stated on its pages |
| MCP server | No official server listed | No official server listed |
