US Nursing Jobs API - JobsIndex by Aspen Tech Labs

Access US nursing jobs through the JobsIndex API, built by Aspen Tech Labs. JobsIndex aggregates 6M+ active US job listings daily from over 175K employer source sites, sourced directly from company career pages and ATS platforms, not scraped from job boards. The nursing job category alone covers over 650,000 active US job postings from 18,500+ unique employer domains, updated every day.

Approximately 60% of nursing jobs come directly from employers such as health systems and hospital networks such as Trinity Health, DaVita, and Addus, with the remaining 40% sourced from recruitment agencies and staffing firms. This gives you full market coverage across both direct-hire and agency-sourced nursing roles.

This Actor covers the full breadth of US nurse and nursing roles, from registered nurse (RN) and licensed practical nurse (LPN) to nurse practitioner, LVN, nurse anesthetist, and travel nurse positions. Within each role type, data is organized into granular subcategories by specialty: cardiology, critical care, behavioral health, dialysis, bone marrow, brain injury, correctional, and many more. Travel nurse variants are also included across role types.

This Actor serves two primary use cases: teams that want to publish nursing job listings on their platform, and teams that need structured nursing workforce data for matching algorithms, AI model training, or healthcare workforce intelligence.

What You Can Use It For

• Power a niche healthcare job board, nurse recruiting platform, or niche travel nurse jobs site with fresh jobs across all major US nursing roles and specialties
• Feed a matching platform with structured nursing data, filterable by role, subcategory, location, salary, or posting age
• Monitor nursing hiring demand across US states, cities, and metro areas, useful for healthcare workforce planning, market research, or sales intelligence
• Analyze advertised salary and seniority signals across RN, LPN, NP, and travel nurse roles by location and specialty
• Collect structured US nursing jobs for training datasets, research, or product development

Built-In Search Preset

This Actor is fixed internally to country=United States and category=Nursing. Both fields are shown in the input example, and the runtime always enforces those values even if different values are submitted. Users can narrow the search by nursing role, location, salary, company, posting age, employment type, or seniority.

Because the enforced country and category take precedence over where and what in the current JobsIndex API, those free-text inputs are intentionally not exposed. Use the structured job and location filters below to narrow results without replacing the preset.

Location Filtering

This Actor is fixed to country=United States. Use structured location filters to narrow results within the US:

• region
• city
• postal_code
• metro_area

Limits and Pagination

This Actor uses the JobsIndex jobs API. Results are paginated with page and size.

Parameter	Default	Min	Max
page	0	0	Depends on size and the item cap
size	5	1	100

Individual numeric bounds are checked before a run starts. Query-dependent pagination is checked after the run starts, as explained below.

One Run, One Page

Each run requests one page, not all available pages. size is the requested number of jobs for that page, with an absolute maximum of 100. Company filters can reduce the effective page size to 5 or 20; see Item Caps below.

For searches without company filters, the retrieval window is 1000 jobs: page * size must be less than 1000. The page number is zero-based.

size	Valid page range	First page outside the window
100	0-9	10
20	0-49	50
10	0-99	100
1	0-999	1000

The last page can contain fewer jobs than requested. For example, page=12, size=80 starts at job 960 and can return up to 40 jobs. Narrow the search with filters to retrieve a different result set beyond the window; the Actor does not change the requested page or paginate automatically.

The input schema checks page and size individually. It cannot pre-validate their combination: page=10, size=100 passes the individual bounds but is rejected after a run starts, so the run can still finish as FAILED.

Item Caps

The maximum number of retrievable jobs depends on the query shape:

Query shape	Max items	Effective max size	Over-size behavior
No company filter	1000	100	Validation error; not silently capped
Company filter plus another keyword or filter	20	20	Silent cap with capping metadata
Company filter only	5	5	Silent cap with capping metadata

A company filter means company_name or company_domain. Another filter means a value in fields such as title, sub_category, industry, posted, salary, employment_type, remote, or seniority. The fixed country and category preset remains part of every request.

Because this Actor always applies the built-in country=United States and category=Nursing preset, company-filtered requests normally use the 20-item company|keywords cap.

When a company-filtered request asks for size greater than the effective cap, the API returns up to the capped number of results instead of erroring. The response metadata includes:

• size_requested - the original requested size
• size_capped_by - "company" for the 5-item cap or "company|keywords" for the 20-item cap

On uncapped responses, size_requested and size_capped_by are not present.

No-company-filter requests are not silently capped. If the request exceeds the 1000-item retrieval window, the API can return 400 Item limit reached. Maximum of 1000 items can be retrieved.

Field Validation

Apify validates the input schema before creating a run, including requests made directly through the API. A schema violation returns HTTP 400 with error.type = invalid-input; no run is created. API clients should handle this response when starting the Actor; there is no run ID to poll or run error file to fetch.

Input	Accepted values / limits
page	Integer 0-999; the usable maximum also depends on size and query shape.
size	Integer 1-100; company capping remains upstream.
company_domain	A domain name only, e.g. example.com; 3-100 raw input characters. No protocol, path, port, or internal spaces. The API trims surrounding ASCII whitespace.
posted	Recommended windows: 1d, 1w, 1m, 1y, or a real calendar date (YYYY, YYYY-MM, YYYY-MM-DD). Use 2-10 raw input characters. Surrounding ASCII whitespace is trimmed after the raw length check. Relative amounts use 1-4 digits without leading zeros.
salary	2-30 raw input characters. 1-9 digits plus h, d, w, m, or y; a range needs units on both ends, e.g. 20h-30h. Surrounding ASCII whitespace is trimmed. Decimals and currency prefixes are not accepted.
employment_type	2-50 raw input characters in total. Comma-separated values; 1-31 characters per item after trimming surrounding spaces. No empty items.
seniority	2-50 raw input characters in total. Comma-separated values; 1-31 characters per item after trimming surrounding spaces. No empty items.
remote	remote, on-site, hybrid, or an empty string for no filter.
Other text fields	Raw input character ranges: region (2-80), city (2-100), postal_code (3-15), metro_area (2-100), title (2-200), company_name (2-150), sub_category (2-100), industry (2-100). Empty optional inputs remain allowed.

Empty optional text fields are allowed and are omitted from the upstream request. Raw input length means the decoded string including surrounding whitespace, before API trimming, not URL-encoded bytes. The schema checks preliminary formats, list structure, and lengths, not whether a matching location, employer, role, or job exists. The API retains its detailed character checks, including permitted Unicode characters in list values. A valid search with no matching jobs succeeds with an empty dataset.

Query-dependent pagination, combined filters, and other backend-only checks remain upstream or runtime checks. If they reject a request after a run starts, the run can still finish as FAILED. Technical errors are not reported as successful searches.

Output

Each run stores job records in the default Apify dataset. The dataset schema includes an Overview table for the most useful fields and a Raw data (all fields) table for the complete JobsIndex record.

Example dataset item:

{
  "id": "3956505510037809027",
  "title": "Registered Nurse - Emergency Room",
  "company_name": "Example Health System",
  "category": "Nursing",
  "sub_category": "Registered Nurse",
  "country": "United States",
  "region": "Texas",
  "city": "Fort Worth",
  "salary_value": "42.00-55.00",
  "salary_currency": "USD",
  "salary_unit": "HOUR",
  "employment_type": "Full-Time",
  "remote": "remote",
  "posted": "2026-04-20",
  "url_apply": "https://example.com/apply"
}

Field availability depends on the source job posting.
