HTTP 100 Continue vs 402 Payment Required
HTTP 100 (Continue) is a 1xx Informational response, while 402 (Payment Required) is a 4xx Client Error response. 100 indicates that the server has received the request headers and the client should proceed to send the request body. This lets the client know it can continue with the request or abort if the headers were rejected. In contrast, 402 means that reserved for future use. Originally intended for digital payment systems, some APIs use it to indicate a billing or subscription issue.
