}'Note: when you use reasoning (thinking) models, some client software, such as LiteLLM, might fail to process reasoning content. In this case, try the https://nano-gpt.com/api/v1legacy endpoint instead of https://nano-gpt.com/api/v1. For more information, refer to the documentation.
Accountless x402 requests return a live 402 quote instead of asking for an API key, card, dashboard, or pre-funded balance.
One unauthenticated request
Supported endpoints return 402 Payment Required with payment.accepted[].

Use quote-and-complete rails or exact X-PAYMENT replay when a wallet signs the payment payload.
