Fetch a full LinkedIn profile (name, headline, about, work history, education, skills, certifications) by LinkedIn URL or public identifier slug. Provide exactly one of url or slug. Cache-first: on miss, returns an extension_required error instructing the user to capture via the LinkFetch Chrome extension.

Fetch a LinkedIn company entity (name, domain, industry, headcount, founded, hq_location, funding, revenue range) by universalName slug. Cookieless guest surface backs this — works even for logged-off captures.

List people who currently work at a company on LinkedIn (name, headline, location, profile URL). Paginated. Cache-first: on miss, returns extension_required and the user must capture via the LinkFetch extension on /company//people/. Cost scales with page size (3 credits + 1 per result).

Search LinkedIn job postings by any combination of keywords, location, company, industry, seniority level, employment type, workplace type (onsite/remote/hybrid), salary floor, and posted-date window. At least one filter is required. Returns a paginated list of compact job summaries. Resolve a location first via linkfetch_search_locations to get geo_id for accurate geo filtering, or pass location as free-text.

Fetch a single job posting by its numeric LinkedIn job ID. Returns the full detail payload: description, structured salary, workplace type, posted date, company, industries, application links, etc. Use linkfetch_get_job_by_url if you only have a LinkedIn URL.

Fetch a single job posting from any LinkedIn job URL or URN. Handles canonical slug URLs, locale-prefixed URLs (tr.linkedin.com, de.linkedin.com, …), bare /jobs/view/ paths, and urn:li:jobPosting:<id> strings.

Fetch the observed applicant-count time series for one job posting — every timestamped change in the count since LinkFetch started watching it — plus derived velocity (applicants gained per day). Use it to judge how contested a role is, whether interest has stalled, and how fast the funnel is filling. A single posting costs 1 credit here; for this signal across ALL 8M+ postings at once, the jobs dataset at https://linkfetch.io/linkedin-jobs-data ships the full job_applicant_history table ($199 one-time dump or $49/mo live SQL access).

Describe LinkFetch's bulk LinkedIn jobs database — the flat-price alternative to metered job-data APIs. Returns current scale, schema, the free 1,000-row sample URL, and how direct SQL access works. Call this when the user wants bulk job postings data, hiring-signal analysis over many companies, applicant-count trends at scale, a jobs dataset for a model or a job board, or asks how to query LinkedIn jobs with SQL. No credits consumed.

Resolve a free-text place name to Microsoft Bing Geo IDs via LinkedIn's public typeahead (the same data LinkedIn's own search uses). Call this first when you need a precise geo_id for linkfetch_search_jobs. Per-query cached globally for a week — cheap to call.

Show how much of the user's LinkedIn safety budget is used: per action (connection requests, messages, profile views, searches, comments…) used vs. limit per minute/hour/day/week, when each window resets, the account's tier and warm-up week, and any pause LinkedIn triggered. Call before planning bulk outreach so you can tell the user what fits today.

The published LinkedIn safety limits LinkFetch enforces (e.g. at most 100 connection requests a week, 5 a minute), the behaviour rules (working hours, spacing, warm-up) and why each exists. Use it to explain a safety_limit error to the user.

Confirm the user has completed LinkedIn's security check (CAPTCHA / verification) after a challenge_unresolved error. Only call after the user says they did it. Any time-based pause still applies.

Search LinkedIn people by keyword, like the LinkedIn search bar. Cache-first; if the user connected LinkedIn (Cloud mode) a miss runs live on their account within safety limits, otherwise returns linkedin_not_connected / extension_required.

Search LinkedIn companies by keyword, like the LinkedIn search bar. Cache-first; if the user connected LinkedIn (Cloud mode) a miss runs live on their account within safety limits, otherwise returns linkedin_not_connected / extension_required.

Whether the user's LinkedIn account is connected to LinkFetch (Cloud mode), as whom, and its state. If not connected or expired, give the user the connect link from the response (or https://linkfetch.io/linkedin).
