AI & Machine Learning Jobs API - JobsIndex by Aspen Tech Labs

Access AI and machine learning job postings data through the JobsIndex API, built by Aspen Tech Labs.

JobsIndex aggregates 11M+ active jobs daily from 300K+ employer sources worldwide. Jobs are sourced directly from company career sites and ATS platforms, not scraped from job boards. That means cleaner data on AI jobs with direct application links where available.

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

What You Can Use It For

• Power a job board, niche AI careers site, or job search feature with fresh, normalized AI and machine learning jobs
• Feed a matching platform or recommendation engine with structured AI jobs by role, skills, location, seniority, employer, and more
• Train or fine-tune AI models using real-world artificial intelligence job postings as source data
• Track AI and machine learning hiring demand across markets and geographies for workforce analytics or competitive intelligence

Built-In Search Preset

This Actor is fixed internally to category=Information Technology and sub_category=AI Specialist. 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 country, structured location, role keywords, salary, company, posting age, employment type, or seniority.

Quick Start

{
  "country": "United States",
  "size": 5
}

Salary Filter Format

Use:

NUMBER[UNIT]

or:

NUMBER[UNIT]-NUMBER[UNIT]

Supported units:

• h - per hour
• d - per day
• w - per week
• m - per month
• y - per year

Examples:

• 20h-30h - hourly rate between 20 and 30
• 35h - fixed hourly rate
• 20h-200000y - range from hourly to yearly comparison

Advanced Filters

what and where support plain-text search, boolean logic, and field-targeted search.

If no field is provided, the API expands the search across a default set of relevant fields.

Plain keyword examples:

what = engineer OR manager
where = United States

Field-specific examples:

what = @title engineer OR manager
where = @country United States

Multi-field examples:

what = @(title,description) (python)
what = @(title,title_raw,description) (engineer OR manager)
what = @(title,description) (python AND developer)

where = @(country,region,city,metro_area,county,sub_city) (United States)
where = @(city,region,metro_area) (San Francisco OR California)
where = @(city,region,metro_area) (California)

When using where, avoid sending separate structured location parameters for the same request unless you want those structured parameters to take priority. For example, country, region, city, postal_code, and metro_area can override or narrow where.

Common job/content fields for what:

• title, title_raw, description, reference
• category, sub_category, seniority, industry, company_type
• company_name, company_domain, company_name_raw
• employment_type, remote, language
• posted, posted_raw, expired
• url_source, url_apply
• salary_value, salary_currency, salary_unit
• id

Common location fields for where:

• country, region, city, metro_area, county, sub_city, postal_code

Location Filtering

For precise location matching, use structured filters exposed for this Actor:

• country
• region
• city
• postal_code
• metro_area

Use where only as a free-text location search when the structured location filters above are not set. If where is provided together with structured location filters, the structured filters take priority and where may be ignored or deprioritized.

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

Invalid page or size values can return 400 Invalid page or size parameters.

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, company_domain, or a company field referenced inside what. Another keyword or filter means anything in what other than company_*, or a value in fields such as title, category, sub_category, industry, posted, salary, employment_type, or seniority where available on this Actor.

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.

Free-Text Query Limits

what and, where available, where support advanced matching syntax but have safety limits:

Limit	Value	Error behavior
Raw URL length before decoding	700 characters	400 'what' or 'where' parameters exceed 700 characters
Decoded text length	500 characters	400 MATCH input exceeds length limit
Combined operator characters: ?, +, pipe, @	20	400 Too many MATCH operators
Unsafe SQL-like keywords	blocked	400 Unsafe MATCH expression

Unsupported characters may be normalized before search. Unbalanced quotes and trailing @ characters may be stripped.

Field Validation

Invalid filter values can return 400 Invalid value for parameter: <name>. Common validation examples include malformed company domains, invalid dates or relative posted values, invalid salary format, invalid job IDs, unsupported location formats, or overly long field values.

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": "14242019290845606376",
  "title": "ML Engineer",
  "company_name": "Example AI Company",
  "category": "Information Technology",
  "sub_category": "AI Specialist",
  "country": "Canada",
  "region": "n/a",
  "city": "n/a",
  "salary_value": "178,000.00-228,000.00",
  "salary_currency": "USD",
  "salary_unit": "YEAR",
  "employment_type": "Full-Time",
  "remote": "remote",
  "posted": "2026-05-07",

}

Field availability depends on the source job posting.
