Details

4SAPI is a service that lets you choose APIs from multiple major AI models in one place. It offers the latest models such as , kimi-k3, and supports enterprise integrations and tax invoice issuance. 栖影AI, a new image-generation tool released by the same team, lets you use models such as image-2 and banana pro.

After signing up for 4SAPI, leave your numeric user ID in a comment on the post to receive $2 in free credits. For every 10th comment, three people will be selected by lottery to receive an additional $3 in credits. Credits are sent by direct message as top-up codes. If the recipient's inbox is full and delivery fails, an administrator will issue them directly within 24 hours. If a comment selected for the lottery was posted by the author or has been deleted, the person in the immediately preceding position receives the prize instead. 栖影AI gives new users 20 points and sign-up benefits just for registering, and you do not need to leave your ID.

Currently, 4sapi.com cannot be accessed directly from mainland China networks. You need to enable a circumvention program or use a backup address, https://4sapi.org or https://4sapi.net. The issue is limited to the access address; the API service itself is operating normally, and the data is exactly the same, so you can continue using the service as usual by changing only the address. Users who use overseas addresses are not affected. The team will announce when access is restored.
