Search for lookalike companies with pagination and filtering. | ERROR: Unable to calculate price.
Output
A paginated list of companies that are similar to the provided seed domains, including company profiles and metadata, along with pagination information indicating total results and current page.
Example use cases
Prospecting list from top customers
“I want to find companies that look like salesforce.com and hubspot.com — show me page 1 with 25 results, and filter for SaaS companies in North America at the Series B or Series C stage.”
Competitive landscape discovery
“Find me 30 companies similar to notion.so and airtable.com, filtered to early-stage startups with fewer than 200 employees anywhere in Europe.”
Account-based marketing targeting
“Give me a list of lookalike companies based on our top accounts — stripe.com, twilio.com, and brex.com — filtering for fintech companies at Series A with 10 to 100 employees, page 1.”
Technical details
Endpoint
POSThttps://x402.orthogonal.com/leadsforge/lookalikes/searchWhen to prefer
Use this endpoint when you need to discover companies that resemble a known set of seed companies — ideal for building prospect lists, doing competitive research, or finding TAM segments. It is preferable over keyword search when you have existing company domains and want structurally similar companies rather than keyword matches, and when you need filtering by geography, company size, funding stage, or category.
Side effects
- Invalid or unresolvable domain in the domains array returns an empty or partial result set
- Unsupported location, category, or funding stage filter values may return an error or be ignored
- Exceeding page size limits may return a validation error
- No lookalikes found for niche domains returns an empty results array
- Payment failure (x402 protocol) prevents the call from completing
