Clay
Clay is an AI-native sales prospecting and GTM data orchestration platform built around Clay Tables — spreadsheet-like workspaces that combine 150+ data providers, AI research agents, and outbound automations. Clay's developer surface is integration-oriented rather than a traditional public REST API: HTTP API enrichment columns, incoming and outgoing webhooks, a Chrome extension, and native connectors to CRMs, sequencers, and data providers. External systems push data into Clay Tables and consume enriched rows via webhooks or exports back to systems of record.
Clay publishes 1 API on the APIs.io network: Public API. Tagged areas include Prospecting, Go-To-Market, Sales, Enrichment, and Automation.
The Clay catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Clay’s developer surface includes changelog, CLI, API reference, getting-started guide, support, authentication, documentation, and 38 more developer resources.
