# Flash API (coming May 2026)

## <mark style="color:orange;">TL;DR</mark>

Flash API is Definitive’s new, institutional-grade, trade execution API that lets any wallet, app, or AI agent offer advanced onchain trading — without building it themselves.

> 💡 **Wallets. Exchanges. Apps. Agents. — One API. Single execution layer for Stop Loss, Take Profit, Limit, TWAP, Quick Trade & Market orders. EVM + Solana. Non-custodial. Smart routing for 200+ DEXs & MMs. MEV protected.**

Flash competes on **advanced execution** for the next generation of wallets and agents that need more than a quote-and-calldata model.

Unlike our [Existing Client API](/developers/existing-client-api.md), Flash API **does not r**equire you to deposit into Definitive’s trading vault wallet infrastructure.

## <mark style="color:orange;">Who Flash API Is For</mark>

* Crypto wallets looking to add advanced order types (TWAP, Limit, Stop, Take Profit, Quick Trade) as an additional revenue stream without a 6+ month engineering sprint
* AI Trading Agents that need a simple, reliable execution layer for autonomous trades on EVM + Solana
* Embedded wallet apps where trading is one feature, not a core product you want to spend 6+ months building
* Fintech and neobanks that need onchain trading-as-a-feature as an additional revenue stream or differentiator

Features exclusively available via Definitive Flash API not offered by the top trading API providers.
