# Overview

DART — Dynamically Allocated Real Time Routing for best swap execution on Solana.

> **Beta** — The DART API is currently in beta.

The DART API provides swap quotes for selected token pairs on Solana via Titan's **DART (Dynamically Allocated Real Time)** engine.

This is a dedicated DART-only endpoint — it exclusively uses the Titan DART provider for routing. DART dynamically re-optimizes trades at the exact moment of execution, not just at quote time — **guaranteeing best execution when it matters most.**

**Base URL:** `https://api.titan.exchange/dart`

**Free to use** · No API key required · JSON responses · Up to 1 bps fee · 1 req/sec rate limit
