What Olostep Company Data API is
Olostep Company Data API looks up a company by name and returns normalized firmographic information from a live web search. Responses may include industry, description, founding year, headquarters, employee count, total funding, website, and LinkedIn. The service searches relevant pages, synthesizes fields, and includes a sources array containing the URLs used. If a field cannot be determined confidently, it returns NOT_FOUND instead of inventing a value. JSON results can feed storage, analysis, CRM systems, and downstream workflows. Olostep lists sales enrichment, market and investment research, CRM data hygiene, competitive intelligence, and AI agents as use cases. Integrations include Claude Desktop, n8n, Cursor, LangChain, Apify, Mastra, Zapier, Relay, and MCP-compatible clients. Batch processing accepts up to 100,000 URLs in one job, with parallel results in 5–8 minutes. Trial costs nothing for 500 successful requests; Starter costs $9 a month for 5,000. Higher plans include larger request allowances and concurrency. Data is not stored by default, while request logs are purged after 30 days.
