## Run this action

Use the TypeScript SDK for one call. Use `ctx.tools.execute(...)` inside a Play for durable calls, scheduled calls, or CSV processing.

```ts theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'limadata_reverse_email_lookup',
  {
    "email": "jane.doe@example.com"
  },
);

console.log(result.toolResponse.raw);
```

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute limadata_reverse_email_lookup --input '{
  "email": "jane.doe@example.com"
}' --json
```

## Example response

The SDK returns this shape at `result.toolResponse.raw`. The example values illustrate the response.

```json theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
{
  "data": {
    "linkedin_url": "https://www.linkedin.com/in/jane-doe",
    "github_url": "https://example.com",
    "x_url": "https://example.com"
  }
}
```

Use `deepline describe limadata_reverse_email_lookup --json` for the latest machine-readable contract.

## Input reference

Find the LinkedIn, Github and X profile URLs from a person's email address. #### Usage notes - We search through our comprehensive database and live sources to match the email address to a person's profile. - This works with both work and personal emails. - LinkedIn is required by default. If all `require_` flags are unset, the request behaves as if `require_linkedin=true`. - If you require LinkedIn profile to be found, set `require_linkedin` to `true`. - If you require X profile to be found, set `require_x` to `true`. - When `require_x` or `require_linkedin` is `true`, we return a 404 response if the required profile is not found and you won't be charged any credits. - If both are set to `true`, we return a 404 if either profile is not found. - Only charged when a profile is found #### Rate limit This endpoint is exempt from the global rate limit and can support higher concurrency.

| Name | Type | Required | Default | Details |
| - | - | - | - | - |
| `payload.email` | `string` | Yes | — | Person's email address. Example: [jsmith@company.com](mailto:jsmith@company.com) Minimum length: 1. |
| `payload.require_linkedin` | `boolean` | No | — | Set to true if you require LinkedIn profile to be found, else return 404. |
| `payload.require_x` | `boolean` | No | — | Set to true if you require X profile to be found, else return 404. |
