Apollo provides a public API for programmatic access to its contact and company database, enrichment workflows, and GTM automation features. Native integrations are available for Claude, ChatGPT, Gmail, and a Chrome Extension, with 200+ additional integrations covering the broader GTM tooling ecosystem. Waterfall enrichment allows developers to chain multiple data sources to maximize field-level completeness on contact and company records. The platform's four pricing tiers (Free, Basic, Professional, Custom) gate credit volumes, AI features, call recording, advanced CRM integrations, SSO, and security controls. Credits are pooled across the team, allocated upfront at the start of each billing cycle, and expire at cycle end with no rollover. Enterprise (Custom tier) unlocks SSO, advanced security configurations, and dedicated support channels.
