# Xingchen Agent Micro-Utilities

> A paid web-API suite of 10 deterministic developer microservices for autonomous AI agents, priced at 0.01 USDT0 per call and settled on-chain via the OKX APP x402 v2 protocol on the X Layer network. All 10 tools are pure-algorithm implementations with sub-10-millisecond latency, zero private-key custody, and no large language model in the serving path, which makes every result reproducible and hallucination-free.

Key facts: 10 tools; sub-10 ms latency; 0.01 USDT0 per call; X Layer chain (eip155:196); x402 v2 payments via facilitator https://x402.okx.com; zero-private-key mode; zero-LLM mode.
