Response Fields

Field	Type	Description
`success`	boolean	Whether the enrichment was initiated successfully
`mode`	string	`sync` or `async`
`enrichment_type`	string	The enrichment type used
`enriched_count` / `total_count`	integer	Number of prospects enriched

`remaining_credits`	integer	Your remaining credit balance
`webhook_url`	string	(Async only) Webhook URL if provided
`results`	array	(Sync only) Enrichment results for each prospect

How It Works

Validation: Checks if you have enough credits
Credit Deduction: Deducts credits upfront from your account
Status Update: Sets prospects to “Loading…” status
Background Processing: Enrichment happens asynchronously
Auto-Update: Prospects are automatically updated when data is found

Important Notes

Asynchronous: Enrichment happens in the background. Results appear gradually.
Credit Deduction: Credits are deducted immediately, even if enrichment fails for some leads
Automatic Filtering: Only prospects without valid emails/phones are enriched
PEOPLE Lists Only: This endpoint only works for people lists, not company lists
Refunds: If an email/phone is not found, credits may be refunded (varies by type)

Monitoring Enrichment Progress

Since enrichment happens asynchronously, you can poll the lead list to check progress:

def wait_for_enrichment(lead_list_id, timeout=300):
    """
    Poll the lead list until enrichment is complete or timeout.
    """
    start_time = time.time()

    while time.time() - start_time < timeout:
        response = requests.get(
            f"{BASE_URL}/public/lead-lists/{lead_list_id}/leads/",
            headers={"X-API-Key": API_KEY},
            params={"page": 1, "page_size": 100}
        )

        prospects = response.json()['prospects']
        loading_count = sum(1 for p in prospects if p.get('email') == 'Loading...')

        if loading_count == 0:
            print("✓ Enrichment complete!")
            return True

        print(f"Still processing... ({loading_count} prospects remaining)")
        time.sleep(10)

    print("⚠ Timeout reached")
    return False

Best Practices

Check Cost First: Always use the count endpoint before enriching
Start Small: Test with a small batch before enriching thousands
Monitor Credits: Keep track of your credit balance
Batch Processing: Enrich in batches rather than all at once
Waterfall for Higher Success: Use FIND_EMAIL_WATERFALL for better results (costs more)
Phone Last: Phone enrichment is expensive (30 credits) - use sparingly
Check Results: Poll the lead list to verify enrichment completed successfully
