KYO AG is a DEX aggregator and meta-aggregator API for AI agents and developers. Aggregator API — Rust-powered, mathematically optimized routing. 54% win rate in 8,000+ quote tests against 10+ aggregators. Meta-Aggregator — Compares 14 aggregators across 19 chains. Real executable quotes, one-time approval, zero gas waste. Agent-ready — LLM skill files for 1-prompt integration. Zero fee, competitive quotes, 19+ chains and cross-chain. All you need for agents.
Hey PH! We built KYO AG — a DEX aggregator and meta-aggregator for both end users and developers/AI agents.
For frontend users — Meta-Aggregator at kyo.ag:
Tired of manually checking multiple aggregators to find the best swap rate? KYO AG's meta-aggregator compares 14 aggregators across 19 chains in real-time, showing you the actual best quote.
Unlike other comparison tools that show simulated estimates, we fetch real executable quotes from each aggregator. And with one-time token approval, you can swap through any aggregator without repeated approve transactions burning your gas. It feels like using one aggregator, but you're getting the best price from all of them.
For developers & AI agents — API:
We prepared LLM skill files (docs.kyo.ag/skills.md) so your AI agent can call our swap API with 1-prompt integration. Just point your agent to the skill file and it knows how to swap tokens.
Speed matters more than you think:
A slow routing engine means the quote you see isn't what you get. By the time a slow API responds, prices have already moved. Our Rust engine returns quotes faster than any aggregator we've tested — so what you see is what you actually receive.
Proven performance:
We ran 8,000+ head-to-head quote competitions against 10+ leading aggregators. KYO AG achieved a 54% win rate — returning the best price more often than any single competitor.

Zero extra fees:
Unlike 1inch, 0x, and others that embed fees in quotes unless you're on a paid plan, KYO AG has zero extra fees. What you see is what you get.
For B2B partners:
We offer monetization and revenue sharing opportunities for teams integrating our API.
Getting started:
- Use the app: kyo.ag

Would love feedback from anyone building AI agents, DeFi tools, or just looking for better swap rates!
