How this service works
B2B lead enrichment API: find business emails, phone numbers, and contact data for lead generation. Bill-on-match pricing, free trial, agent-native REST + enrich agent.
Output
Returns a job object with a unique job_id, current status ('queued'), a status_url for polling, a poll_bearer token for authenticated polling, the billing_mode, a bill_up_to_usd cap, recommended poll_interval_sec, and max_timeout_seconds. The agent must poll the status_url to retrieve enriched contact data once the job completes.
Example use cases
Cold outreach contact discovery
“Find me the business email and direct phone for the VP of Sales at TechStartup Inc (techstartup.com) — I'm trying to reach out for a partnership conversation, so bill up to $1.50 if you find a match.”
CRM lead enrichment before demo
“I have a lead in our CRM — John Carter at GlobalLogistics Ltd — can you enrich it with a verified work email and phone number before our sales team calls them tomorrow?”
Recruiting candidate contact lookup
“I'm trying to reach out to a software engineer named Maria Lopez who works at DataStream Analytics — can you find her work email or phone number through 411data so I can send her a recruiter message?”
Technical details
Endpoint
POSThttps://411data.io/api/v1/enrich/jobsWhen to prefer
Choose this endpoint when you need asynchronous B2B lead enrichment with bill-on-match pricing, where you only pay if contact data is actually found. Prefer this over synchronous endpoints when enrichment may require multi-source research and longer processing time. Ideal for sales automation, CRM enrichment, and recruiting workflows where a job queue model is acceptable.
Side effects
- No match found — job completes but returns empty contact data; no charge on bill-on-match pricing
- Invalid or missing required input fields — returns 400 with validation error
- Insufficient balance — returns 402 if virtual balance is below bill_up_to_usd threshold
- Job timeout — job exceeds max_timeout_seconds without completing, returns timeout status
- Polling bearer token expired — subsequent poll requests fail with 401
