Logo.dev

Product Introduction

1. Logo.dev is an API-driven service that provides instant access to millions of company logos, stock ticker symbols, and cryptocurrency project logos for integration into web applications, dashboards, and enterprise systems. It serves structured logo data through developer-friendly API endpoints with global CDN delivery and automatic fallback mechanisms. The platform maintains daily updates to ensure logo accuracy across both public and private companies worldwide.
2. The core value lies in eliminating manual logo management for developers while guaranteeing UI consistency through reliable brand assets. It solves critical pain points in fintech applications, SaaS platforms, and internal tools by providing pixel-perfect logos with sub-100ms response times globally. The service reduces user drop-off rates during onboarding flows by replacing placeholder graphics with verified brand imagery.

Main Features

1. The API supports multiple identifier types including company names, stock tickers (NASDAQ/NYSE), cryptocurrency symbols, ISIN codes, and domain names through a single RESTful endpoint. Developers can request logos in webp/png formats with size parameters from 16px to 512px, optimized for retina displays through the retina=true parameter. All responses include fallback options like monogram initials when exact matches aren't available.
2. Global CDN infrastructure delivers cached logos with 99.9% uptime across 200+ edge locations, ensuring sub-second load times worldwide. The system automatically updates logos daily through automated verification processes with primary sources and user-submitted corrections. Cache invalidation occurs within 15 minutes of logo updates while maintaining version history for 30 days.
3. Smart fallback mechanisms activate when no direct match exists, first attempting domain-based matches (walmart.com → Walmart logo), then generating monogram initials from company names. The fallback system includes automatic color contrast adjustment to maintain UI readability and provides JSON metadata about match confidence levels for debugging purposes.

Problems Solved

1. Manual logo curation creates significant technical debt for product teams, requiring constant updates for mergers, rebrands, and new market entries. Traditional solutions like Clearbit lack specialized support for financial instruments and crypto assets, forcing developers to maintain multiple vendor integrations.
2. The primary target users are engineering teams building fintech platforms requiring stock/crypto logos, SaaS products needing company branding during onboarding flows, and enterprise systems processing transaction data with merchant logos. Specific verticals include job board platforms, CRM systems, and financial dashboards.
3. Typical use cases include automatically displaying correct merchant logos in banking apps (e.g., "SBUX_STORE_321_NYC" → Starbucks logo), showing up-to-date stock logos in trading interfaces, and maintaining consistent employer branding on career sites without manual design team involvement.

Unique Advantages

1. Unlike generic logo APIs, Logo.dev provides specialized handling for financial identifiers including 150+ global stock exchanges and 20,000+ cryptocurrency projects. The system cross-references multiple authoritative sources like SEC filings, exchange websites, and official brand guidelines to verify logo authenticity.
2. The platform introduces dynamic logo versioning that allows developers to pin specific logo iterations (e.g., pre-rebrand logos) through API version parameters. Advanced matching algorithms process raw transaction descriptors and partial company names with 93% accuracy across 52 languages.
3. Competitive differentiation comes from three technical pillars: 628 million domain-to-logo mappings for precise matching, dedicated infrastructure for financial/crypto assets, and machine learning models that predict branding changes 14 days before public announcements through pattern analysis.

Frequently Asked Questions (FAQ)

1. How frequently are logos updated in the system? Logo.dev performs daily batch updates at 02:00 UTC, incorporating new companies, rebrands, and design changes verified through multiple sources. Real-time updates occur for critical financial instruments within 15 minutes of exchange notifications.
2. What happens if no logo exists for a specific merchant string? The API first attempts fuzzy matching on the provided text, then returns a fallback monogram generated from the company name with complementary background colors. Developers can configure fallback strategies through API parameters like fallback=monogram|none|placeholder.
3. Does the API support stock tickers from non-US exchanges? Yes, coverage includes 150+ global exchanges such as LSE, TSE, and HKEX with support for both ticker symbols (e.g., 7203.T for Toyota on Tokyo Exchange) and ISIN codes. Exchange-specific identifiers can be prefixed in requests (e.g., LON:HSBA for HSBC on London Stock Exchange).
4. What CDN providers does the service use? Logo.dev utilizes a multi-CDN strategy combining Cloudflare, Fastly, and AWS CloudFront, automatically routing requests through the fastest available edge node. All logos are served with immutable cache headers and Brotli compression for optimal load times.
5. Can we migrate from Clearbit without code changes? The API offers a compatibility mode that mimics Clearbit's response structure through the ?migration=clearbit parameter, including identical field names and error codes. A dedicated migration guide documents rate limit differences and authentication method transitions.
