LeadIQ

LeadIQ is a B2B sales intelligence and contact data platform headquartered in Santa Clara, California (with engineering in Singapore and Brisbane) that helps outbound sales teams identify, capture, enrich, and engage prospects across Salesforce, HubSpot, Outreach, Salesloft, Gong, and other revenue tools. The product portfolio includes Prospector (Chrome extension for contact capture with verified work emails and direct-dial mobile phones), Scribe (AI message writer), Refresh / CRM Enrichment (continuous contact and account hygiene for Salesforce and HubSpot), Champion Tracking (job-change alerts on existing contacts), AI Account Prospecting (ICP-fit account and persona discovery), and Lando — an agentic AI assistant that fuses first-party CRM data with LeadIQ's third-party intelligence behind a conversational interface. LeadIQ exposes a public GraphQL Data API at https://api.leadiq.com/graphql for programmatic people search, company search, advanced grouped search, prospect-list management, usage reporting, and data-feedback submission, authenticated via HTTP Basic auth with an API key issued in the LeadIQ dashboard. The same API surface is also reachable through a Model Context Protocol (MCP) server so AI agents (including Claude) can query verified contact and account data conversationally. LeadIQ actually runs three programmable surfaces over one data core: the GraphQL Data API, a REST Prospector API at https://prospector.leadiq.com described by an OpenAPI 3.1.0 document LeadIQ serves publicly (14 operations for lists, prospects, email verification, Salesforce export and caller identity), and a remote MCP connector at https://mcp.leadiq.com/mcp with seventeen tools behind OAuth 2.0 and dynamic client registration. The published rate limit is 60 requests/minute (Standard), with credit-based metering in Universal Credits where a verified work email costs 1 UC, a direct phone 10 UC, company firmographics 3 UC and a profile 0.1 UC. All plans get 50 one-off test calls; sustained API access is sales-gated.

LeadIQ publishes 4 APIs on the APIs.io network, including GraphQL API, Account API, Lists API, and 1 more. Tagged areas include Sales Intelligence, B2B Data, Contact Data, Lead Generation, and Prospecting.

LeadIQ’s developer surface includes authentication, documentation, API reference, getting-started guide, pricing, signup flow, engineering blog, and 44 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/leadiq: open an issue to ask a question, or submit a pull request to add artifacts.
