Every signal carries its type, subtype, strength, polarity, dated event, source and evidence URL, so you can audit exactly what drove a company's stage — or build your own scoring on top. **Scope this call to specific companies.** Pass `domain_search_id_list`. The signal table is very large, and a request filtered only by market or date range does not complete inside the gateway timeout — the connection is dropped after about 60 seconds. Company-scoped calls typically return in well under a second. For company-level results use [Expansion Search](/en/api-reference/endpoint/expansions/market_lookup); for one company's feed use [Company Signal Events](/en/api-reference/endpoint/expansions/company_pulse_events). ## OpenAPI ````yaml en-openapi POST /expansions/signals/search openapi: 3.0.0 info: description: >- The Pubrio API delivers market expansion intelligence — real-time signals that flag when a company enters a new market — alongside the company and people data beneath them.
