Note that `officeLocationsV2` is a different filter and takes country `apiCode`s from GET /companies/filter-options, not these place names. Same vocabulary as the product's type-ahead; free. Errors: - `422` `VALIDATION_FAILED` — The request failed the declared schema; `param` names the offending key and `message` quotes the rule it broke. - `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. Requires one of the following token scopes: companies. ## OpenAPI ````yaml /openapi.json get /business/companies/autocomplete openapi: 3.1.0 info: title: Fuse Business API version: 1.0.0 description: >- External API for lists, campaigns, prospect search and contacts.
