🤖 AI Prompt

I want to use the "Share Link Resolution (V1)" API from Just One API.
Base URL: use https://api.justoneapi.com by default. Mainland China users can use http://47.117.133.51:30015 instead.
API Path: /api/xiaohongshu/share-url-transfer/v1?token=YOUR_API_KEY&shareUrl=VALUE
API Endpoint: BASE_URL + /api/xiaohongshu/share-url-transfer/v1?token=YOUR_API_KEY&shareUrl=VALUE
HTTP Method: GET
Authentication: Append the "token" query parameter to the URL.
OpenAPI Definition: https://docs.justoneapi.com/openapi/xiaohongshu-rednote/share-link-resolution-v1-en.json

Parameters:
- token (query): Access token for this API service. (Required)
- shareUrl (query): A Xiaohongshu (RedNote) short share URL beginning with http://xhslink.com/ or https://xhslink.com/. (Required)

Return format: safely handle JSON or text according to the actual Content-Type.

Response Handling & Error Codes:
1. Business results should be determined by the "code" field in the response body (code 0 means success).
2. Timeout Recommendation: Set the request timeout to 120 seconds. If 120 seconds is too long for your use case, use at least 60 seconds, but a small number of requests may time out before receiving a result.
3. Business Code Reference:
   - 0: Success
   - 100: Invalid or Inactive Token
   - 301: Collection Failed. Please Retry.
   - 302: Rate Limit Exceeded
   - 303: Daily Quota Exceeded
   - 400: Invalid Parameters
   - 500: Internal Server Error
   - 600: Permission Denied
   - 601: Insufficient Balance
   - 602: Token Budget Exceeded
4. Code 601 means the shared account balance is insufficient. Code 602 means the current API token's own cumulative budget limit has been reached. Token budget limits do not transfer funds out of the shared account balance.

Please help me write a script in my preferred programming language to call this API and handle the response.
