LeadIQ Prospector REST API
REST API for LeadIQ's saved prospecting workspace — create and read prospect lists, create prospects singly or in batches of up to 100, search saved prospects, verify email deliverability, and export a saved prospect into the caller's Salesforce as a Lead or Contact with duplicate detection. Fourteen operations under /v1, described by an OpenAPI 3.1.0 document LeadIQ serves publicly at https://prospector.leadiq.com/openapi.json. Authenticates with the base64-DECODED LeadIQ API key in an X-API-Key header (the GraphQL Data API takes the same key in its encoded form), or with a bearer JWT. This is the surface LeadIQ's own MCP tools AttachProspectToList, CreateProspect, SearchProspects, VerifyEmail, VerifyProspectEmail and ExportProspectToSalesforce are built on.
