3. CoinStats API — Best for Multi-Chain Data Aggregation & Portfolio Integration
Company Overview: CoinStats started as a portfolio tracking application used by over 1.2 million monthly users and has since opened its data infrastructure to third-party developers through a public REST API. The API provides aggregated, pre-structured data rather than raw blockchain RPC access, which means developers receive clean wallet balances, transaction histories, DeFi position data, and market feeds without needing to parse low-level on-chain responses.
Core Strengths
- 120+ Blockchain Networks: Unified wallet balances and transactions across Solana, Ethereum, Bitcoin, and the full range of EVM-compatible chains (Polygon, Arbitrum, Hyperliquid, Tron), all returned through one endpoint and one consistent schema.
- 200+ Exchanges: Aggregated market data from centralized and decentralized exchanges, including Binance, Coinbase, Hyperliquid, and others, with real-time pricing, volumes, and market caps for thousands of cryptocurrencies.
- 10,000+ DeFi Protocols: Staking positions, lending balances, LP holdings, and yield data are automatically detected and returned alongside standard wallet balances, with no additional integrations required.
- Portfolio Data Access: Developers can pull portfolio data already stored in CoinStats (total value, holdings breakdown, P/L, performance charts) via a ShareToken-based authentication flow, making it possible to embed portfolio views into custom applications.
- News and Market Sentiment: Aggregated cryptocurrency news and trending topics from trusted sources, useful for building research dashboards or sentiment-aware trading tools.
- 100,000+ Coins: Real-time and historical pricing data, market caps, and volume metrics covering over 100,000 cryptocurrencies across both on-chain tokens and exchange-listed assets.
Pricing
CoinStats uses a credit-based pricing model. Developers receive a free plan at signup, then upgrade only when they need more credits or higher rate limits. Credit usage scales with endpoint complexity and request parameters. For example, querying a single-chain wallet balance costs fewer credits than requesting balances across all supported networks in one call.
Specific credit multipliers are documented transparently, and developers can track their usage in real time through the API dashboard.
Free tier included with paid plans available for higher volumes.
Documentation Quality: Well-organized docs hub at coinstats.app/api-docs with endpoint references and code examples.
