Technical details
Endpoint
POSThttps://x402.orthogonal.com/findymail/api/lookalike/searchWhen to prefer
Use this endpoint when you need to discover companies that are similar to a known seed domain for sales prospecting, competitive analysis, or market research. It is especially well-suited for building outbound lead lists from an ideal customer profile, and supports large result sets up to 10,000. Prefer this over keyword search when you have a specific reference company rather than a topic or keyword.
Side effects
- Invalid or unresolvable seed domain returns an error
- Limit exceeding 10,000 is rejected
- Invalid exclusion list IDs may cause filtering errors or empty results
- Insufficient credits for the requested result size
- Seed domain with no known lookalikes returns an empty list
