素材上传

# 1. Reserve: POST /api/v1/uploads with file_name, file_type, file_size
# 2. PUT bytes to data.upload_url with every data.required_headers value
# 3. Complete: POST /api/v1/uploads/{reservation_id}/complete
# 4. Pass the returned opaque media id in input.media_ids

稳定错误契约

code	HTTP	meaning
invalid_request	400	Request fields or owned media are invalid
unauthorized	401	API key is invalid, expired, or revoked
insufficient_credits	402	Account balance cannot fund the task
forbidden	403	The key does not have the required scope
not_found	404	The owned generation or media was not found
idempotency_conflict	409	The key was reused with another public request
rate_limited	429	Retry after the Retry-After interval
provider_rejected	502	The task was rejected and exposes no upstream details
service_busy	503	Retry safely with the same Idempotency-Key

API Key 只在创建时显示一次并且只能保存在服务端。每次生成都必须提供稳定的 Idempotency-Key；网络重试复用原键，有意创建新任务时才使用新键。实时模型字段以 GET /models 为准，额度用量通过 GET /usage 查询。
