HappyHorse

HappyHorse models are called through one unified, asynchronous job API. Start a task with POST /api/generate, then poll GET /api/generate/{taskId} until it finishes. This family exposes 7 endpoints.

Overview

Every endpoint shares the same envelope — only model and the input fields change. Run any from the Models Market playground.

Authentication

Create an API key at /api-keys, then send it as a Bearer token. Requests from the browser while logged in also work via the session cookie.

Authorization: Bearer <YOUR_API_KEY>

Create Task

POST
POST https://97ai.97claude.com/api/generate

Body: { "model": "<slug>", "input": { … } }

Response: { "taskId": "<id>", "state": "waiting" }

Query Result

GET
GET https://97ai.97claude.com/api/generate/<taskId>

Response: { "taskId", "state": "waiting" | "success" | "fail", "resultUrls": [ … ], "creditsConsumed", "failMsg", "balance" }

Asynchronous
A 200 from Create Task only means the task was accepted — not finished. Poll this endpoint until state becomes success or fail. Failed tasks are not billed.
