The server starts monitoring after HTTP 201 and continues even if the client disconnects or never polls; this endpoint never drives task processing; reading a ready result preserves the existing one-time settlement behavior. It returns processing until the server persists ready, or HTTP 504 timeout after the 120-second deadline. ## OpenAPI ````yaml /openapi/hcaptcha.json post /captcha/tasks openapi: 3.0.0 info: title: hCaptcha verification code recognition service version: 1.0.0 description: >- API reference for hCaptcha verification code recognition service on Ace Data Cloud. servers: - url: https://api.acedata.cloud description: Ace Data Cloud API security: - bearerAuth: [] paths: /captcha/tasks: post: summary: Tasks description: >- Read the persisted status of a server-managed asynchronous captcha task.
