+## Detail
+
+```
+GET https://www.linkedin.com/jobs-guest/jobs/api/jobPosting/<jobId>
+```
+
+Returns a single job's HTML: title (`top-card-layout__title`), company
+(`topcard__org-name-link`), location (`topcard__flavor--bullet`), the rich description
+(`show-more-less-html__markup` / `description__text`), and job-criteria items
+(seniority, employment type, job function, industries).
+
+## Notes

+- No authentication required.
+- Respect rate limits — the CLI backs off on 429/5xx.
+- Country-agnostic: pass any `--location` (city, region, country, or "Remote").
