LeadIQ Prospector REST API is one of 3 APIs that [LeadIQ](https://apis.io/providers/leadiq/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include REST, Prospecting, Contact Data, and CRM Enrichment. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and authentication docs.

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.
