# Overview

> Syncro Sui Data Stream is a low-latency transaction streaming product that provides direct access to Sui network transaction flow in real time.

The service allows external clients to observe transactions across multiple stages of their lifecycle — from initial network ingress through consensus ordering to final execution — and submit transactions directly into the network pipeline.

The API is designed for latency-sensitive infrastructure, trading, analytics, and indexing workloads that require fast access to live transaction data before it becomes available through public RPC infrastructure.

The `/v1/*` route family exposes WebSocket and HTTP endpoints for:

* observing incoming transactions
* monitoring consensus-ordered transactions
* consuming post-execution transaction data and events
* submitting transactions directly to the network

All `/v1/*` payloads are serialized with BCS. Each WebSocket frame contains one complete BCS document with no additional envelope or framing layer.

## Route catalogue

| Method | Path          | Protocol | Payload (BCS-encoded)                               |
| ------ | ------------- | -------- | --------------------------------------------------- |
| GET    | /v1/incoming  | ws       | `sui_types::transaction::Transaction`               |
| GET    | /v1/accepted  | ws       | `consensus_core::block::SignedBlock`                |
| GET    | /v1/pending   | ws       | `PendingTxStreamMessage`                            |
| GET    | /v1/executed  | ws       | `TxStreamMessage`                                   |
| POST   | /v1/submit-tx | HTTP     | request body: `Transaction`; response: `text/plain` |

Server may send WebSocket `Ping` frames every \~30 s; respond with `Pong` (most client libraries do this automatically). Slow subscribers whose receive mailboxes stay full are dropped.
