**Canonical:** https://apis.io/apis/a5x/a5x-technical-interfaces/  
**Provider:** A5X — https://apis.io/providers/a5x/  
**Documentation:** https://portal-tecnico.a5x.com.br/login

A5X Technical Interfaces is published by [A5X](https://apis.io/providers/a5x/) on the [APIs.io](https://apis.io/) network. Tagged areas include Trading, Market Data, Post-Trade, FIX Protocol, and Derivatives. The published artifact set on APIs.io includes API documentation.

The trading, market data and post-trade interfaces A5X exposes to exchange participants — order entry and drop copy over FIX, a binary market data feed, and post-trade capture, allocation, positioning and risk messaging. Message catalogs, session recovery rules, order identifier formats and field limits are documented in the A5X Dev Portal (Portal Tecnico), which requires credentials; no public machine-readable contract (OpenAPI, AsyncAPI, GraphQL SDL or downloadable FIX dictionary) is published at an anonymous URL, and the exchange had not begun production operations as of this profile.
