Billed at $1.00 minimum on a successful match; vendor costs above $1 are passed through at 30% markup.
Example use cases
Pre-sales outreach contact research
“I need to reach out to Greenfield Manufacturing in Columbus, Ohio — can you find their main phone numbers, any key decision-makers with titles, and their business address so I can prepare my outreach list?”
Legal compliance due diligence
“Before we send the demand letter, can you pull up all publicly available legal associates — attorneys, registered agents — for Pacific Rim Imports LLC in Los Angeles? I also need their address and any known phones.”
Investor target background check
“We're considering reaching out to BlueSky Ventures in San Francisco — can you find their public phones, people on record with job titles, address, and any legal counsel associated with them from web sources?”
Technical details
Endpoint
POSThttps://411data.io/api/v1/enrich/websearchWhen to prefer
Choose this endpoint when you need managed, web-researched enrichment for a business entity and require not just basic contact data but also key personnel with titles and legal associates (attorneys, registered agents) for compliance-aware outreach. It is preferable over directory-only lookups when the target company may not be in structured databases, and over person-search endpoints when the primary query entity is a business rather than an individual.
Side effects
- No match found — business name too ambiguous or not indexed publicly (no charge on no-match)
- Partial match — some fields returned but others unavailable due to sparse web presence
- Rate limit or quota exceeded — API returns an error requiring retry
- Invalid input — missing required business name field returns a validation error
- Vendor upstream failure — web research provider unavailable causing a timeout or error response
