The API key belongs to the integration partner; the person scanning the QR code does not need an AiToEarn account and does not need to authorize or bind a REDnote account in advance. Provide your own mobile sharing page and encode its URL as the offline QR code. The landing page should call the integration backend, which calls this endpoint and returns `verifyConfig` to the frontend for `xhs.share`. Never expose the API key to the frontend. This endpoint only generates `verifyConfig`. It does not accept images, video, title, or body, does not create an AiToEarn publish record, and does not return the final post result. Pass the sharing content when the integration frontend calls `xhs.share`. Request the signature when the user is ready to share, use the `nonce`, `timestamp`, and `signature` from the same response together, and do not cache it for a long time, mix fields from different requests, or reuse it across multiple sharing attempts. A successful `xhs.share` callback only indicates that the SDK invocation or app launch succeeded; it does not confirm that the user finally published the post. Each API key can call this endpoint up to 60 times per 60 seconds. ## OpenAPI ````yaml /openapi/en/aitoearn.openapi.json post /api/v2/channels/rednote/open/offline-qr/share-config openapi: 3.0.1 info: title: AiToEarn Open Platform API description: >- AiToEarn Open Platform API.
