latestOpenAPI 3.1.02026-07-22103475.9 KBSearch Lookalikes Bulk
Asynchronous, high-volume variant of Search Lookalikes. Same lookalike engine and inputs, but it accepts up to 10000 companies and runs as a background job: the call returns a job_id immediately, and you poll a separate endpoint for status + paginated results.

Find lookalike companies from either a natural-language description or a set of seed company websites, with optional firmographic filters.
Use it for queries such as:
- Healthcare companies building with voice AI
- Companies that provide customer support software for B2C
- Companies that build workflow automation for non technical industries
Or supply 1-10 seed company websites and let OpenFunnel synthesize the query for you.
Two input modes
At least one of query or seed_domains is required. Both can be combined for a hybrid trait.
- Natural language (query): describe the kind of company you want.
- Seed-based discovery (seed_domains): pass up to 10 company websites and OpenFunnel uses them to synthesize the lookalike query for you. The response manifest echoes back the LLM-synthesized derived_query, plus resolved_seed_domains and unresolved_seed_domains.
- Both together: pass seed_domains AND query - the query becomes a must-have angle layered on top of the seeds.
Omitting filters
If you omit filters, search runs across all company sizes, funding stages, and supported locations. Use the optional firmographic filters (min_employees, max_employees, funding_stages, locations) to restrict to your ICP.
Discovering available firmographics
The funding_stages, locations, min_employees, and max_employees filters accept a fixed set of values. Fetch the current set via GET /api/v1/account/firmographic-options - it returns the accepted funding_stages labels, the supported HQ locations (code + name), and the min/max employee bounds.
Polling for results
This endpoint responds immediately with a job_id and status: "pending". Poll GET /api/v1/account/search-lookalikes-bulk/{job_id} ("Search Lookalikes Bulk Results", listed under Agent Helpers) until status is completed, then walk the result pages using next_cursor. A large limit can take minutes - polling avoids a long-held connection.
Credits
1 credit per company returned, charged when the job completes. Empty result sets are free. The amount is echoed in the manifest's credits_consumed.
Cancelling a job
If you need to stop a running or pending job early, call POST /api/v1/account/search-lookalikes-bulk/{job_id}/cancel. The job moves to a transient cancelling state and stops at its next checkpoint; whatever companies were already delivered stay readable via the poll endpoint, and you are charged only for those - nothing for the abandoned remainder.
The response returns a job_id; then poll GET /api/v1/account/search-lookalikes-bulk/{job_id} for status and results.
