# Prospecting Contacts

Search for contacts that match your Ideal Customer Profile using rich filter criteria.

Filter by contact attributes:
- Job title, seniority, department
- Location (city, state, country, continent)
- Existing data points (e.g. only contacts with a known work email)
- Signal activity (promotion, job change)

Filter by company attributes:
- Size, revenue, industry, technologies
- Location, intent topics, funding

Results are paginated up to 50,000 total (1,000 pages × 50 results). Use the returned contact id values with Enrich Contacts to reveal emails and phones.

> Billing: Charged per result via api_search. If signals are requested, an additional charge applies per matched signal per result.
