OpenAI's new WebSocket mode reduces latency for AI agents, while 0x's Cross-Chain API enables multi-chain swaps across 15+ blockchains in under a minute. These updates reflect a broader shift toward real-time, event-driven architectures designed for autonomous agents rather than manual, batch-processed legacy systems.
