"expected_company": "Old Example Robotics",
"credits_consumed": 3,

}
```
***
## Success Messages
| Message | Meaning |
| ------------------------------------------------------------- | -------------------------- |
| `No job change detected. Still employed at expected company.` | Person still at company |
| `Job change detected. Person has moved to a new company.` | Person changed jobs |
| `Never worked at the expected company.` | No employment record found |
***
## Best Practices
Run weekly checks on your top accounts to catch job changes early.
Job changers in their first 90 days are 3x more likely to buy. Reach out quickly.
When your champion moves, reach out at their new company - they already know your value.
Check multiple contacts in parallel to efficiently monitor your database.
***
## Use Cases
Follow your product champions when they move to new companies.
Know when key contacts leave accounts before renewal conversations.
Automatically trigger outreach when contacts move to target accounts.
Keep contact records accurate by detecting role changes.
