# 接口限制说明

- [HTTP接口限制](https://docs.infoway.io/getting-started/api-limitation/http.md)
- [WebSocket限制](https://docs.infoway.io/getting-started/api-limitation/websocket.md)
- [免费套餐查询限制](https://docs.infoway.io/getting-started/api-limitation/free-plan.md): 免费套餐面向产品体验与接入验证，付费套餐面向正式行情服务。为使各套餐的服务范围与其用途相符，并保障行情服务的质量与稳定性，免费套餐的可访问标的将予以收敛。
