Use `fiberIndustries` for `industriesV2`, `linkedinIndustries` for `linkedinIndustries`, `crunchbaseIndustries` for `crunchbaseCategories`, `crunchbaseCategoryGroups` for `crunchbaseCategoryGroups` (case-sensitive — copy them verbatim), `companyTags` for `tags`, `naicsCodes[].code` for `naicsCodes`, `countries[].apiCode` for both `headquartersCountryCode` and `officeLocationsV2`, and `accelerators[].acceleratorSlug` for `acceleratorsV2`. Filters with no enumerable vocabulary are documented on the request schema instead: `status` (active / acquired / closed), `stage` (pre_seed, seed, series_a…series_j, public, acquired, closed, private_equity, venture_other, no_funding_yet, unknown), `fortuneRankings` (fortune-500 / fortune-1000) and `technologies`; company names, investor domains and `headquartersCity` place names come from GET /companies/autocomplete. Static vocabulary: no tenant data and no credits. Errors: - `429` `RATE_LIMITED` — Per-token rate limit for this bucket exhausted; retry after the window in the RateLimit-Reset header. - `500` `UNEXPECTED_ERROR` — The request failed inside the service; nothing was billed and the request_id identifies the failure.
