Interest Signals

​

Data categories

• Investor activity. Which investors are showing interest (signal_investors, returned as names).
• Signal strength. A confidence score (signal_score, 1–10) based on engagement patterns.
• Target. The company or person the interest is focused on (signal_type is Company or Talent).
• Context. A plain-English signal_summary, plus funding context at signal time (signal_total_funding_usd, signal_last_funding_date) and signal_date.
• Source type. Where the signal was observed (source_types: insider, venture_capital, angel, journalist, influencer, investment_bank, private_equity, investor).

Endpoints

​

How to use the API

• A company → Get company investor-interest signals. Every signal attributed to that company, newest first.
• An investor → Get investor-interest signals. Everything that investor has shown interest in.
• A person → there’s no per-person endpoint; sweep Get investor-interest signals by date and keep the Talent-type signals whose entity_id is the person_id you’re after.

• entity_id → Get company by ID (Company signals) or Get person 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 Enrich investor or Search entities by 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.
• Every endpoint here is charged per signal returned, so bound the date range before widening pages. The entity-scoped endpoints page at 50 results; see each endpoint’s “Costs” note.
• On the entity-scoped endpoints an unknown company or investor returns 404, while a known one with no signals returns 200 with an empty array.
