# Introduction

> Crustdata's public Company, Person, Job, Web, and Social Post APIs for search, enrich, identify, autocomplete, and content retrieval.

Crustdata provides public APIs for the data layer behind sales,
recruiting, and research workflows. You can query indexed datasets of
companies, people, jobs, and social posts, enrich a known entity with
fresh attributes, resolve identifiers, search the web, and fetch page
content — all over a single versioned REST surface.

<Note>
  Every endpoint in this version requires `Authorization: Bearer <key>`
  and `x-api-version: 2025-11-01`. Live endpoints (real-time retrieval
  from the web) are enterprise-only and plan-specific — review
  [Pricing](/general/pricing) before you build against them.
</Note>

## API areas

Five product areas, grouped by entity. Pick the area for the entity you
work with; each area's introduction page walks the simplest query and
links onward to filters, pagination, and the full reference.

<CardGroup cols={2}>
  <Card title="Company" icon="building" href="/company-docs/search/introduction">
    Search the indexed company dataset, enrich a known company, resolve a
    domain/name/URL to a Crustdata ID, and surface valid filter values with
    autocomplete.
  </Card>

  <Card title="Person" icon="user" href="/person-docs/search/introduction">
    Search the indexed people dataset, enrich a known person, discover developer
    profiles, and surface valid filter values with autocomplete.
  </Card>

  <Card title="Job" icon="briefcase" href="/job-docs/search/introduction">
    Search the indexed job-listings dataset with filters, cursor pagination, and
    aggregations. Fetch real-time openings for a single company on demand.
  </Card>

  <Card title="Web" icon="globe" href="/web-docs/search/introduction">
    Search the web across news, web, scholar, social, and deep-research sources,
    or fetch the HTML content of any URL.

  </Card>
</CardGroup>

## What lives where

Every API area's section opens with a
short overview (orientation), then progressive how-to pages (filters,
pagination, recipes), and finishes with reference (the full request /
response schema). Use this map to pick the right page for your task:

| If you want to…                                   | Go to                                                                                                    |

| Build a query step-by-step                        | The area's **Filters**, **Pagination**, **Recipes** pages                                                |

| Port an existing integration from the legacy APIs | [Migration guides](/migrations/overview)                                                                 |

## First call

If you haven't called the API yet, start with the simplest possible
request — Company search by name, then layer filters from there.

```bash theme={"theme":"vitesse-black"}
curl --request POST \
  --url https://api.crustdata.com/company/search \
  --header 'authorization: Bearer YOUR_API_KEY' \
  --header 'content-type: application/json' \
  --header 'x-api-version: 2025-11-01' \
  --data '{
    "filters": { "field": "basic_info.name", "type": "=", "value": "Crustdata" },
    "limit": 1
  }'
```

Continue with [Company search](/company-docs/search/introduction) or
jump to any of the [API areas](#api-areas) above.

## Migrating from the legacy APIs?

If you have an integration on the legacy `/screener/*` or `/data_lab/*`
endpoints, head to the [Migration guides overview](/migrations/overview)
— it lists every legacy endpoint, its current replacement, and the
universal changes (auth scheme, version header, error envelope) that
apply across every migration.
