Hust Media Public API v3

This note shows how shared API routing, payload validation, and response handling keep utility requests consistent, supporting platform growth through cleaner service flows and stable integration behavior.

Introduction

This note documents the current v3 API contract behind the platform utilities. It focuses on the shared gateway structure, service-based request routing, and the response handling rules used by the client so integration and operational behavior stay consistent over time.

Authentication

All current utilities route through the same v3 gateway and require an API Key in the JSON body. Requests use Content-Type: application/json, while routing is handled by service and payload structure rather than separate endpoints for each utility.

Endpoint

POST /api/v3

This endpoint is the shared submission layer for the current utilities. In the client flow, each request starts with action: "add", username: "", a normalized national_market value ("vi" or "en"), and a utility-specific service id.

Request Body

The current client logic uses one common request contract and then adjusts a few fields per utility. Core fields include action, key, username, national_market, service, link, comments, and quantity. The exact payload branch is selected by service id together with fields such as link, comments, or images_data.

In practice, link, comments, and quantity are reused differently depending on the selected service:

• Text to Speech sends normalized text through link with a fixed quantity.
• Speech to Text sends audio as base64 data in comments.voice_data, with quantity derived from rounded audio duration.
• Image to Text sends uploaded image data through images_data, with a fixed quantity of 1.
• Vietnamese to English sends trimmed source text through comments, with quantity based on trimmed character length.

Response Handling

The client reads response.text() first, then attempts JSON parsing, and falls back to the raw text as a message when parsing fails. A request is treated as successful only when response.ok is true and the returned payload does not include an error field.

Depending on the service, the client reads result data from message, order, voice, text_vip, or text. For text-returning utilities, text_vip is preferred when both text fields are available.
