The Specter API is built around three kinds of data — core data, signals, and your team’s network — plus workflows for finding and pulling them: lists, saved searches, and AI search.

​
Core Data

The foundational entities you can search, enrich, and expand:

Companies

Firmographics, funding, headcount, growth, and historical data.

People

Professional profiles, career history, and contact information.

Investors

Funds and angels, including investment focus, activity, and portfolios.

Transactions

Funding rounds, acquisitions, and IPOs.
Each entity has a stable ID and is designed to link seamlessly across the system, enabling traversal between companies, people, investors, and transactions.

​
Signals

Time-based insights that capture change, momentum, and intent:

Talent Signals

Career moves, stealth activity, and leadership changes.

Interest Signals

Which investors are tracking which companies — and how strongly.

Revenue Signals

Real-time indicators of company revenue and growth momentum.

News Signals

Real-time detection of company-relevant news and events.
Signals are designed for monitoring, alerting, and powering real-time workflows on top of the underlying data.

​
Network Mapping

Your team’s LinkedIn relationship graph.

People in your network

Everyone your team is connected to on LinkedIn, deduplicated across teammates.

Companies in your network

Where those contacts work, ranked by how many you know there.

Your network at a company

Who you know at a target company, their roles, and which teammates are linked.

Team members

Your active team roster, to resolve teammate IDs back to named people.
Use it to find a warm path into a target account, or see who already knows a given contact.

​
Workflows

Ways to find records and pull them in bulk, not one at a time.

Lists

Curated sets of companies, people, or investors you pull on demand.

Saved searches

Turn a search you’ve saved in the app into a live API feed.

AI Search

Query every product in plain English.
Any list or saved search must be shared with the API to be reachable from your integration.

​
Make your first call

Every request carries your team’s key on the X-API-Key header. This example calls Enrich companies to look up a company by its domain: 
curl --request POST \
  --url https://app.tryspecter.com/api/v1/companies \
  --header 'X-API-Key: YOUR_API_KEY' \
  --header 'Content-Type: application/json' \
  --data '{ "domain": "tryspecter.com" }'
A match comes back as JSON. The Quickstart walks you from API key to your first result.
Access is approval-based — there’s no self-serve signup. Request an API key via the API Console; approvals are typically granted within one business day. Usage is metered in credits. See Plans & Pricing for details.
