[OI]-compatible LLM inference API for autonomous agents
[OI]-compatible LLM inference API for autonomous agents. Supports reasoning, coding and chat workloads. Pay with USDC on Base using x402 (upto scheme, true-up billing): the 402 quotes a spending CAP (estimated input tokens + your max_tokens at the model's per-1M price), and after the model answers you are settled for the ACTUAL usage — always <= the cap, never more. Minimum $0.001, cap $3.0 per call. Cached input bills at 10%. Failed calls are never charged. Any model from GET /v1/models.
