Endpoint
POSThttps://gpt55.558686.xyz/v1/tools/answer/standardWhen to prefer
Choose this endpoint when you need a reliable, short-to-medium answer grounded in provided context text at a standard quality tier ($0.0025/call), and you are already paying via x402 USDC on Base. Prefer this over the mini tier when answer quality matters more than cost. Prefer this over the GPT-5.5 endpoint when cost savings matter and the task is standard QA rather than complex reasoning.
