Excerpt（摘录）

AxonHub describes itself as an AI gateway / unified API platform.
Key statements:

• README.zh-CN: “AxonHub 是 AI 网关，让你无需改动一行代码即可切换模型供应商。”
• README.zh-CN: “一个 API 格式对接 10+ 供应商”
• docs/en/api-reference/image-generation.md: supports image generation via the OpenAI-compatible /v1/images/generations endpoint
• docs/zh/guides/cost-tracking.md: supports three pricing modes: flat_fee, usage_per_unit, usage_tiered
• docs/zh/guides/cost-tracking.md: flat_fee means fixed fee per request
• internal/objects/price.go: PricingModeFlatFee = “flat_fee”
• internal/server/biz/cost_calc.go: in flat_fee mode, subtotal ignores quantity and directly uses FlatFee

Interpretation note:
AxonHub clearly supports per-request fixed-fee billing in its cost model.
It also supports OpenAI-compatible image generation routing.
