  "summary": "Apollo.io is automatable today through its REST API. This record is the Apollo.io sales-intelligence and engagement platform (people and company search, enrichment, contacts, sequences, deals, tasks, and analytics), including the first-party remote MCP at https://mcp.apollo.io/mcp. It is not Apollo GraphQL, HubSpot, Salesforce Sales Cloud, or Gong. Apollo users authenticate with an API key. Partners acting for mutual customers use OAuth 2.0. Most endpoints are available to all accounts; free accounts need a work email for some search, enrichment, and retrieval calls. Enrichment and some search actions consume credits. First-party MCP uses Streamable HTTP. Interactive clients complete OAuth 2.0. Headless clients send a master API key as X-Api-Key; scoped keys return 403 API_INACCESSIBLE. Apollo forbids using MCP traffic for model training. The official CLI (apollo-io-cli) installs via Homebrew or platform binaries and authenticates with OAuth 2.0, with no API key required. Pricing sells a trial that can downgrade to a free-forever Starter plan. Standard plans are for internal business use. Official language SDKs and iPaaS catalogs were not established from the opened pages. Computer-use viability is unassessed. API and MCP each score 8. API is the best path because scoped keys can limit REST access, while headless MCP requires a master key.\n"
