Welcome to the Definitive Trading API
The Definitive Trading API gives developers and builders access to all of the institutional-grade execution and automated trade analytics found in our advanced trading platform.
Built for institutions, protocols, dApps, and AI agents, the API lets you execute trades across 100+ liquidity venues, access advanced order types, and retrieve post-trade data — without the headache of building execution logic, routing algorithms, or parsing block explorer data yourself.
⚙️ Features
Deep Liquidity Aggregation
When you place an order on Definitive we ensure institutional-grade, multi-venue execution by automatically routing orders across 100+ DEXs, PMMs, Liquidity Pools, Contracts, and Aggregators.
Our API provides instant quotes and breakdowns of execution venues for the fills involved.
Advanced Order Types
Definitive supports onchain Market, Limit, TWAP, and Stop order types. Build advanced execution strategies through a unified, low-friction API.
Intent Masking
Definitive is the only platform that offers onchain Market, Limit, TWAP, and Stop orders while keeping intent off-chain.
Unlike traditional protocols that expose strategy details onchain )risking frontrunning and MEV) Definitive separates order creation from execution. This architecture allows you to express complex trading logic without leaking sensitive intent to the network, preserving alpha and improving execution quality.
Gasless Execution
With Definitive, users never worry about gas fees. By leveraging account-abstraction we are able to remove the friction of gas-sponsorship so you can focus fully on trading.
Post-Trade Reporting Analytics
Every trade routed through Definitive returns:
Fill Time
Fill Size
Detailed Price Breakdown
Execution Venues
Fee Details
Skip hours of parsing block explorers with Definitive’s automated post-trade data.
