Crypto APIs evolve to support AI agents and real-time trading

The landscape of cryptocurrency APIs is shifting as AI models increasingly access data directly to perform real-time discovery and endpoint selection. This evolution requires API providers to offer features such as Model Context Protocol (MCP) servers, agent-ready integrations, and pay-per-request access models that bypass traditional account signups.

Key providers in the crypto trading stack include CoinStats API for unified market and wallet data, altFINS for pre-computed trading signals, StealthEX for non-custodial cross-chain swaps, Codex, and Hyperliquid API. Effective API selection now depends on several layers, including aggregated market data, wallet and portfolio state, real-time on-chain data, execution capabilities, and accessibility for AI agents.
