### `classify_contact` (~540 tokens)

Classify Contact

One contact in, one classified row out. Give it a job title and it returns the department, the seniority level, a seniority_rank from 1 to 12 you can filter with a comparison, and classification_rule, the named rule that fired, so every decision is auditable. The classification is a deterministic rule table: it needs no API key, calls no model, and returns the same answer for the same title every time. Only job_title is required. full_name and company_domain are read only when verify_position is on, which checks whether the person is still listed on their employer's own website and adds roughly 3 seconds and 9 requests per contact. The optional LLM fallback for titles the rules cannot place runs on your own key, set as the LLM_API_KEY secret environment variable on your own copy of the actor, and only the title is ever sent, never the person's name. With no key set those titles come back null rather than failing the row. This actor does not discover people: the name and title come from you. Requires an APIFY_TOKEN and consumes Apify credits. Read only.

Input parameters:

- `company_domain` (string): Only needed for position verification. The company's website domain, with or without https.
- `full_name` (string): Only needed for position verification. Classification works without it. This name is never sent to any language model.
- `job_title` (string, required): The contact's job title, exactly as you hold it. Classified by deterministic rules with no API key needed.
- `llm_model` (string): Model id passed straight through to the provider. Only read when the LLM fallback is on. Default: "gpt-4o-mini".
- `llm_provider` (string): Which provider your LLM_API_KEY belongs to. Only read when the LLM fallback is on. Default: "openai".
- `skipCache` (string): Set to true to ignore cached results and classify from scratch. Default: "false".
- `use_llm_fallback` (boolean): Off by default. When on, titles the rules cannot place are sent to your own model using the LLM_API_KEY secret environment variable you set on your copy of this Actor. Only the title is sent, never t…
- `verify_position` (boolean): Check whether the person is still listed on their employer's own website. Off by default. Adds roughly 3 seconds and 9 requests per contact, and needs both the name and the domain. Default: false.
