3) GET  /api/v1/images/{id}          → { "status":"done", "images":["https://img2htm.com/files/generated/….jpg"] }

速率限制

每分钟 60 张图片 per API key. When exceeded the API responds 429 Too Many Requests with a Retry-After: 60 header. Enterprise plans can raise this limit.

指数退避

On 429 or 5xx, retry with exponential backoff: wait 1s, 2s, 4s, 8s … up to 5 attempts, adding random jitter. Never retry 4xx errors other than 429.

delay = min(60, (2 ** attempt) + random(0, 1))

错误代码
