Company logo API

Product Introduction

1. Definition: Hunter.io's Company Logo API is a RESTful web service that programmatically retrieves high-resolution company logos using domain URLs as input. It falls under the technical category of Brand Intelligence APIs.
2. Core Value Proposition: This API eliminates manual logo sourcing by automating instant, accurate logo extraction for any business domain—100% free with zero authentication barriers.

Main Features

1. Domain-to-Logo Retrieval: Submit a company domain URL via HTTP GET request; the API scans public databases and structured data sources (Schema.org, OpenGraph) to return the logo URL in JSON format. No preprocessing or parsing required.
2. Zero-Authentication Access: Unlike competitors requiring API keys or accounts, this service operates without registration, tokens, or rate limiting—ideal for rapid prototyping and scaling.
3. Real-Time Resolution: Leverages Hunter.io’s proprietary web-crawling infrastructure to fetch logos directly from company homepages, ensuring up-to-date results with <500ms average response time.

Problems Solved

1. Pain Point: Manual logo searches consume hours of developer/marketing time and risk outdated/inconsistent assets. This API automates brand asset aggregation at scale.
2. Target Audience: SaaS developers (e.g., CRM, email signature tools), marketing teams managing brand directories, and data analysts compiling company databases.
3. Use Cases: Auto-populating customer dashboards with client logos, generating investor reports with portfolio company branding, or enriching lead databases with visual identifiers.

Unique Advantages

1. Differentiation: Competitors like Clearbit or Brandfetch mandate paid tiers for logo APIs; Hunter.io delivers identical functionality permanently free without usage caps.
2. Key Innovation: Patented domain-matching algorithm cross-references multiple authoritative sources (Crunchbase, LinkedIn) to resolve logos even for obscure domains, achieving 98% accuracy.
