How to use the API

• entity_id → Get company by ID (Company signals) or Get person info by ID (Talent signals). When entity_id is absent, use the embedded company domain or person linkedin_url.
• signal_investors[].name → resolve to a Specter record via Look up investors or Search investor name (the signal carries investor names, not IDs).

​

Good to know

• Signals use UUIDs.
• signal_score is a 1–10 confidence score.
• signal_type is Company or Talent — the target can be a company or a person.
• entity_id is the company ID (Company signals) or person ID (Talent signals); it may be absent, in which case use the embedded company domain or person linkedin_url.
• Investors are returned as names (signal_investors[].name), not IDs — resolve them via investor lookup.
• Saved searches must be shared with the API to be reachable; empty results are valid, not an error.
• Get Investor Interest Signal by ID costs 1 credit per request.
