“I'm running an ABM campaign targeting Salesforce, HubSpot, and Zendesk — can you pull me all the Marketing Directors and CMOs at those three companies with their contact details?”

Technical details
Endpoint
POSThttps://api.agenticdata.host/v1/search/list-buildWhen to prefer
Choose this endpoint when you need to build or filter a targeted list of B2B contacts from a large database (800M+ records) in real time. It is well-suited for outbound sales prospecting, ABM campaigns, and recruiting where you need emails, phone numbers, or LinkedIn profiles for people matching company and persona filters. Prefer it over point-enrichment endpoints when you need to discover new contacts rather than enrich known ones.
Side effects
- Empty results array if filters are too narrow or no matching contacts exist
- Missing email or phone fields if data is not available for matched contacts
- Request rejected if required body fields (type, method, bodyType, body) are missing
- Payment failure if USDC balance is insufficient for the $0.05 per-call fee
- Timeout or degraded response if filter complexity exceeds processing thresholds
