Olostep Company Data API review
A low-cost API for company matching and source-cited firmographic enrichment.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Olostep Company Data API is a web and API product for finding and enriching company records. It matches companies by name and returns structured firmographic profiles with industry, description, founding year, headquarters, employee count, funding, website, and LinkedIn data. The product is aimed at sales enrichment, CRM data hygiene, market research, investment research, competitive intelligence, and AI-agent workflows. Results are returned as JSON, with API-key authentication and cited source URLs included in responses.
Pricing is organized around request volume and workflow capacity. The Trial plan costs $0 and includes 500 successful requests, JavaScript-rendered requests, residential IP addresses, and low rate limits. Starter costs $9 per month for 5,000 successful requests and 150 concurrent requests. Standard costs $99 per month for 200K successful requests and 500 concurrent requests. Scale costs $399 per month for 1 million successful requests and AI-powered browser automations. Enterprise includes hundreds of millions of credits, enterprise-grade reliability, and custom discounts. The published plans show a clear path from limited evaluation to high-volume API use.
The product’s main distinction is its live web search approach rather than a fixed pre-indexed database. It also returns low-confidence fields as NOT_FOUND, which gives downstream workflows an explicit confidence outcome instead of forcing uncertain values into a record. Batch-ready enrichment workflows and structured responses suit databases, CRMs, spreadsheets, and automation pipelines, while AI features support browser automations on the Scale plan. Buyers needing company matching, firmographic data, business-change signals, and cited evidence should consider Olostep. Teams that require technographic data, organizational structure data, or integrations should choose an alternative.
