> Use this endpoint to find a B2B person profile based on the provided email.
# Email to B2B Person Profile
Convert an email address into a B2B person profile. Find the professional identity behind any email.
## Endpoint Details
| Metric | Value |
| -------------- | -------------------------------- |
| **Cost** | **10 credits** per profile found |
| **No Results** | **FREE** if no profile found |
Reverse lookup is more resource-intensive than forward lookup, hence the higher cost.
### Per-Endpoint Limit
| Metric | Value |
| ------------------- | ------------------- |
| **Requests/Minute** | 300 |
| **Burst Capacity** | \~5 requests/second |
Rate limits are subject to change. Custom rate limits are available on enterprise plans — [contact us](mailto:support@leadmagic.io).

## Quick Example
```bash cURL theme={"theme":{"light":"github-light","dark":"github-dark"}}
curl -X POST 'https://api.leadmagic.io/v1/people/b2b-profile' \
-H 'X-API-Key: YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{"work_email": "alex.rivera@example.com"}'
```
```javascript Node.js theme={"theme":{"light":"github-light","dark":"github-dark"}}
const response = await fetch('https://api.leadmagic.io/v1/people/b2b-profile', {
method: 'POST',
headers: {
'X-API-Key': 'YOUR_API_KEY',
'Content-Type': 'application/json'
},
body: JSON.stringify({ work_email: 'alex.rivera@example.com' })
});
const data = await response.json();
if (data.profile_url) {
console.log(`Profile: ${data.profile_url}`);
}
```
```python Python theme={"theme":{"light":"github-light","dark":"github-dark"}}
import requests
response = requests.post(
'https://api.leadmagic.io/v1/people/b2b-profile',
headers={'X-API-Key': 'YOUR_API_KEY'},
json={'work_email': 'alex.rivera@example.com'}
)
data = response.json()
print(f"Profile: {data.get('profile_url', 'Not found')}")
```
***
## Request Parameters
Work email address to lookup. Preferred over personal\_email.
Personal email address to lookup. Alternative identifier.
You must provide either `work_email` or `personal_email` (or both for better match rates).
***
## Response
B2B person profile URL or slug (null if not found)
Credits used (10 if found, 0 if not)
Human-readable status message
### Example Response
```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
"profile_url": "linkedin.com/in/alex-rivera",
"credits_consumed": 10,
"message": "Profile URL found."
}
```
***
## Success Messages
| Message | Meaning | Cost |
| ---------------------------------- | ------------------------------------------ | ---------- |
| `Profile URL found` | B2B person profile successfully identified | 10 credits |
| `No profile found for this email.` | No matching profile found | FREE |
***
## Workflow
Send the work or personal email address.
We search our database for matching B2B person profiles.
Receive the B2B person profile.
Use [B2B Person Profile](/docs/v1/reference/profile-search) to get full profile details.
***
## Best Practices
Work emails have higher match rates than personal emails for professional profiles.
After finding a profile URL, use B2B Person Profile to get complete profile data.
Not all emails have associated professional profiles. Plan for partial enrichment.
***
## Use Cases
Add B2B person profile links to your CRM contacts.
Identify the professional identity behind inbound leads.
Match website visitors to professional profiles.
Fill in missing profile URLs in your contact database.
