Measure the advertised openings observed in a defined corpus. Postings are not completed hires, headcount growth, unique vacancies, or the entire labor market.
Setup
Set CRAWLORA_API_KEY to your key from crawlora.net.
Run the bundled scripts/crawlora.sh from this skill directory or by absolute
path. It sends x-api-key to https://api.crawlora.net/api/v1; keep the key in
the environment. Read reference/endpoints.md for
jobs search, global facets, company discovery, and posting detail.
Define the population before counting
- Specify the role/skill question, locations, providers, employment/workplace
scope, observation date, and required sample coverage. Search
/datasets/jobs/search; open roles are the default.include_closed=trueadds stored closed roles but does not reconstruct past point-in-time vacancies. - Read
/datasets/jobs/facets?size=...for corpus context and labels. This endpoint accepts only bucket size, not search filters. Itstotal_open,remote_open, and buckets are global. Do not use them as the denominator or skill distribution for a filtered search. Buckets are capped, not exhaustive. - Use search fields that actually exist:
qspans title/company/description;city,state,country,department, andjob_familyhave their documented matching behavior.workplace_typeacceptsonsite,hybrid,remote. Skill and seniority facets are not equivalent to server-side search filters. Inspect/classify returned rows when those dimensions define the analysis. - Collect within the agreed bound (
page_size<=100, 10,000-result window). Preserveposting_id, provider, employer, URL, raw location, structured fields, posted date, open status, and available crawl timestamps. Deduplicate by posting ID, then identify likely syndicated/reposted roles using employer, requisition, title, location, and canonical URL. Keep ambiguous multi-location roles explicit. - For skill demand, distinguish required, preferred, and incidental mentions;
a keyword hit in a company description is not necessarily a job requirement.
Treat
seniority_leveland occupation fields as classifications, not employer assertions. Seniority isentry,mid, orsenior, with uncertain roles assigned tomid; ambiguous occupations may lack ajob_familyentirely. - For compensation, retain
compensation_min,compensation_max, currency, period, and source wording.min_salary/max_salaryrequiresalary_currencyand match overlapping range bounds, not guaranteed pay. Currency filtering alone does not normalize hourly/monthly/annual figures; verify period locally. Do not annualize without explicit hours/weeks assumptions or treat base salary as total compensation. Report pay-disclosure coverage before summaries. - Return counts and proportions with a defined denominator: deduplicated
eligible observed postings, unique employers, or salary-disclosing rows.
Multi-skill labels can total above 100%. Label truncated samples and corpus
gaps; raw search
totalis not the deduplicated population size.

Interpretation and reporting
Return query/cohort definitions, coverage and exclusions, counts by relevant dimension, cited example postings, and limitations. A one-time snapshot describes observed demand; trend claims require comparable dated snapshots and stable coverage.
- Structured locations can be missing while enrichment catches up. Missing is not remote, and remote does not mean eligible from every country.
- Some providers omit employment type or posting dates. Do not equate ingestion date with publication date or classify undated roles as newly opened.
- Historical employer visa filings, if returned, are not a role-specific promise. Keep this contextual evidence separate from the demand analysis.
- Salary summaries describe advertised ranges among disclosing postings, not accepted compensation or a representative wage survey. State midpoint choices.
- Back off on
429, retry transient5xxonce, stop on401/403, and check applicationcode. Stop on repeated pages; research does not apply to jobs or contact employers, and a snapshot request does not create ongoing monitoring.
Current search context
For a current multi-employer search sample, use google_jobs separately from
stored dataset counts. It calls POST /google/jobs with a flat JSON body, for
example:
scripts/crawlora.sh -X POST /google/jobs '{"query":"software engineer","location":"San Francisco, CA","page":1}'
This is Google's aggregated job-search surface, distinct from Google's own
careers site at /google-jobs/search. Returned snippets are discovery leads;
verify the employer and posting before using them. Keep this bounded search
sample separate from stored job-dataset denominators, refresh dates, and demand
calculations. Do not infer a filled vacancy or absent demand from an empty result.
