LeadOcean - 2026 Pricing, Features, Reviews & Alternatives

LeadOcean is a cloud-based B2B people and company data API designed for engineers, RevOps teams, AI and agent builders, outbound and demand generation teams, agencies, and data teams that access contact and company data through code, scripts, workflows, or AI agents. The platform aggregates 693M people profiles and 67M company records unified from 20+ licensed and proprietary sources into a single schema, with 366M profiles carrying an email address and 166M carrying a phone number. Access is provided exclusively through a REST API and a hosted MCP server — no CRM, sequencer, dialer, or Chrome extension is included.

LeadOcean exposes three core REST endpoints (people search, people enrichment, and company enrichment) alongside a hosted MCP server at https://api.leadocean.io/mcp with 13 typed, self-describing tools including search_leads, get_lead, find_phone, get_company, search_companies, count_leads, count_companies, and export_leads. People search supports 50 filters and company search supports 34 filters, spanning title, seniority, industry, headcount, revenue, funding, technology stack, location, email status, and reachability. Bulk CSV export handles up to 50,000 rows per request. Every record carries an email deliverability status drawn from 13 classification values ranging from verified to spam_trap, and phone lookup is available via a dedicated endpoint. Person enrichment accepts a LinkedIn URL, email, phone, or person ID and returns current role, company firmographics, skills, education, location, career history, and all verified contact details. Company enrichment accepts a domain. Responses use cursor paging with a stable envelope; unknown fields return null rather than inferred values, and the X-Source response header identifies which dataset answered each request.

The MCP server connects via OAuth 2.1 and is compatible with Claude, ChatGPT, Claude Code, Cursor, Codex, VS Code, Windsurf, and Gemini CLI, allowing AI agents to call search, enrichment, count, phone lookup, and export tools autonomously. A llms.txt reference file allows a model to learn the full API in a single fetch. LeadOcean also integrates with Clay, Zapier, Make, and n8n for workflow automation. Pricing is flat monthly with no per-record charges or overage invoices; a free plan provides 1,000 records for life with full API and MCP access and no credit card required.
