最新报道:APIs act as standardized interfaces enabling software communication, often via HTTP methods like GET or POST, with responses in JSON/XML formats. Common types include REST, GraphQL, WebSocket, and gRPC, each suited for different use cases such as real-time data or microservices. In crypto and AI, APIs provide market data, on-chain analytics, trading execution, and model inference. Key evaluation factors include documentation, latency, data freshness, authentication, reliability, and cost. Security best practices involve HTTPS, secure key storage, rate limiting, and minimal permissions. Platforms like Token Metrics and CoinDesk offer APIs for real-time prices and blockchain insights, supporting AI-driven analytics and decision-making.
