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 the enrichment patch applied to the lead graph: confirmed phone numbers with confidence scores, contact names and titles, billing confirmation (billed/matched flags), coverage metrics, wall time, and a markdown summary of findings. Also includes a persist block with the lead enrichment record ID and idempotency status.
Example use cases
Resolving ambiguous phone match after first pass
“That enrichment session for Greenfield Plumbing in Denver left candidate uc_4a92b1 unmerged because the phone confidence was borderline — re-run it from session sess_88xyz99 and tell me if the number checks out.”
Confirming owner contact for high-value prospect
“We enriched Morris Bakery Supply in Akron last week under session sess_22abc44 and there's an unmerged candidate uc_5f13c2 that might have the owner's direct line — investigate that specific finding and patch the lead.”
Recovering missing email after partial enrichment
“The first enrichment pass on Capital City Auto Parts in Lansing, MI didn't resolve candidate uc_9d05e8 — re-run that finding from session sess_77def11 with extra focus on finding a contact email and owner name.”
Technical details
Endpoint
POSThttps://411data.io/api/v1/enrich/lead-session/finding-rerunWhen to prefer
Use this endpoint when a prior agentic lead-enrichment session left one or more candidate findings unmerged or uncertain, and you need a targeted second pass on a specific candidate rather than re-running the full session. It is the right choice when you have a candidate_id from a backfill.unmerged_candidates array and want to cheaply resolve that single finding without re-paying for a full enrichment run. Prefer this over the full lead-session endpoint when the session is already complete and only one or two candidates remain ambiguous.
Side effects
- candidate_id not found or expired — returns unmatched status with no billing
- chat_session_id invalid or session graph not found — 400 or empty prior_backfill
- lead contact_id mismatch with session — graph patch rejected
- no new data found for the candidate — matched:false, billed:false
- research model unavailable — falls back to default or returns error
- progress_key already cleared from a completed run — stale key error
