Look up LinkedIn industry IDs (deprecated — use /signals/industries)

Find the LinkedIn industry ID for an industry name, so you can filter company search by industry instead of guessing numeric codes.

GET /api/v1/enrichment/company-search takes industryId, but the IDs are not guessable and appear nowhere in a company payload. This endpoint is the lookup: search by name, take the id, pass it to company-search.

Cost: Free. No credits, no rate concerns — it is a static list.

Call it with no parameters to get the complete taxonomy (all 434 industries, ~90 KB). That is the intended way to build an integration: pull the vocabulary once, store it, map your own categories onto the IDs. There is no pagination and no default page size to trip over.

Input:

• search (optional) — an industry or sector name, e.g. "software", "banking", "Manufacturing". Case-insensitive. Matching also covers the hierarchy path, so a sector name returns every industry beneath it.
• limit (optional) — cap the number of entries returned. Omit it and you get them all.

Output — data contains:

• elements — array, best match first (exact name, then prefix, then substring). Each has id (string — pass this as industryId), name, and path (full hierarchy, parents first).
• count — how many entries are in elements.
• total — how many matched in total. It equals count unless you passed limit, so total > count is the only signal that you truncated the list.

Example: ?search=software returns id: "4" for Software Development; then GET /api/v1/enrichment/company-search?industryId=4&keywords=crm returns only software-development companies. Pass several IDs comma-separated to widen the search.
