# Welcome to the Specter API

Specter is a private-markets intelligence platform that provides structured data and proprietary signals on companies, people, investors, transactions, and real-time signals like revenue, investor interest, and talent movement.

More than 300 firms rely on Specter, including venture and corporate VC teams sourcing deals, private equity firms tracking targets, recruiters mapping talent, and B2B sales teams identifying accounts.

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.

## <Icon icon="cubes" /> Core Data

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

<CardGroup cols={2}>
  <Card title="Companies" icon="building" href="/api-ref/products/companies">
    Firmographics, funding, headcount, growth, and historical data.
  </Card>

  <Card title="People" icon="users" href="/api-ref/products/people">
    Professional profiles, career history, and contact information.
  </Card>

  <Card title="Investors" icon="money-bill-trend-up" href="/api-ref/products/investors">
    Funds and angels, including investment focus, activity, and portfolios.
  </Card>

  <Card title="Transactions" icon="money-bill-transfer" href="/api-ref/products/transactions">
    Funding rounds, acquisitions, and IPOs.
  </Card>
</CardGroup>

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

## <Icon icon="bolt" /> Signals

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

<CardGroup cols={2}>
  <Card title="Talent Signals" icon="briefcase" href="/api-ref/products/talent-signals">
    Career moves, stealth activity, and leadership changes.
  </Card>

  <Card title="Interest Signals" icon="eye" href="/api-ref/products/interest-signals">
    Which investors are tracking which companies — and how strongly.
  </Card>

  <Card title="Revenue Signals" icon="chart-line" href="/api-ref/products/revenue-signals">
    Real-time indicators of company revenue and growth momentum.
  </Card>

  <Card title="News Signals" icon="newspaper" href="/api-ref/products/news-signals">
    Real-time detection of company-relevant news and events.
  </Card>
</CardGroup>

Signals are designed for monitoring, alerting, and powering real-time workflows on top of the underlying data.

## <Icon icon="sitemap" /> Network Mapping

Your team's LinkedIn relationship graph.

<CardGroup cols={2}>
  <Card title="People in your network" icon="users" href="/api-reference/network/get-people-in-your-teams-network">
    Everyone your team is connected to on LinkedIn, deduplicated across teammates.
  </Card>

  <Card title="Companies in your network" icon="building" href="/api-reference/network/get-companies-in-your-teams-network">
    Where those contacts work, ranked by how many you know there.
  </Card>

  <Card title="Your network at a company" icon="location-dot" href="/api-reference/network/get-your-teams-network-at-a-company">
    Who you know at a target company, their roles, and which teammates are linked.
  </Card>

  <Card title="Team members" icon="user-circle" href="/api-reference/organization/list-your-teams-members">
    Your active team roster, to resolve teammate IDs back to named people.
  </Card>
</CardGroup>

Use it to find a warm path into a target account, or see who already knows a given contact.

## <Icon icon="bookmark" /> Workflows

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

<CardGroup cols={3}>
  <Card title="Lists" icon="list" href="/api-ref/lists">
    Curated sets of companies, people, or investors you pull on demand.
  </Card>

  <Card title="Saved searches" icon="bookmark" href="/api-ref/saved-searches">
    Turn a search you've saved in the app into a live API feed.
  </Card>

  <Card title="AI Search" icon="sparkles" href="/api-ref/ai-search">
    Query every product in plain English.
  </Card>
</CardGroup>

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](/api-reference/enrichment/enrich-companies) to look up a company by its domain:

```bash theme={null}
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](/api-ref/quickstart) walks you from API key to your first result.

<Note>**Access is approval-based** — there's no self-serve signup. Request an API key via the [API Console](https://app.tryspecter.com/settings/api-console); approvals are typically granted within one business day. Usage is metered in credits. See [Plans & Pricing](/api-ref/plans) for details.</Note>

## Where to go next

<CardGroup cols={1}>
  <Card title="Quickstart" href="/api-ref/quickstart">Request to first result in four steps.</Card>
  <Card title="Authentication" href="/api-ref/auth">API keys, the X-API-Key header and credits.</Card>
  <Card title="Companies" href="/api-ref/products/companies">The core data product and its endpoints.</Card>
</CardGroup>
