## What it's good for

The Companies API is in Enrichment. Reach for it to enrich a company from its domain or name; find companies matching a filter; find companies similar to one you name.

As of 2026-09-28 (catalog revision 85280) it serves 8 jobs through 13 endpoints.

## Access

- **Runs on looot's key** for 13 endpoints: nothing to set up, the run spends your looot balance. You can connect your own key instead; see [Bring your own key](/guides/bring-your-own-key).

## Price basis

1 per call (from $0.0019), 12 charged at the cost the provider reports. A call that fails at the provider costs $0; see [What's free](/money/free-and-failures).

## Free first in fallback

No. Every endpoint bills on each answer, found or not, so a fallback walk pays for a miss here. See [Free first](/concepts/free-first).

## Run it

A job run takes shared input names, not The Companies API's own field names; looot maps them for each provider. For `job:company.enrich`, `domain` is taken by 14 of its 20 providers, `company` is taken by 7 of its 20 providers, `linkedin_url` is taken by 7 of its 20 providers. See [Job inputs](/concepts/job-inputs).

Example input for `looot run` or the MCP [`run`](/mcp-tools/run) tool, with placeholder values:

<CodeGroup>

```bash CLI
looot run job:company.enrich --input '{"domain":"example.com","company":"Example Inc","linkedin_url":"https://www.linkedin.com/in/janedoe"}'
```

```json MCP
{
  "endpointId": "job:company.enrich",
  "input": {
    "domain": "example.com",
    "company": "Example Inc",
    "linkedin_url": "https://www.linkedin.com/in/janedoe"
  },
  "idempotencyKey": "<new unique key>"
}
```

</CodeGroup>

A job run picks among all the job's providers. To run The Companies API itself, name one of its endpoints (MCP [`search`](/mcp-tools/search) with `{"filters": {"provider": "thecompaniesapi"}}` lists them), for example `thecompaniesapi-companies`: `looot inspect thecompaniesapi-companies` prints its exact input fields and price.
