1inch Business is a SaaS Web3 infrastructure platform: subscription-based access to the 1inch ecosystem, built on the same battle-tested swap and execution technology that powers 1inch — packaged as production-grade APIs for developers and businesses building on-chain applications.
One account, one API key, one platform: DEX liquidity aggregation, intent-based and cross-chain swaps, wallet and market data, and blockchain infrastructure across 15+ networks.
Why 1inch Business
The swap, routing, and settlement technology behind these APIs processes real production volume on 1inch itself. You integrate the same engine — not a re-implementation.
A single API key unlocks every product. Plans scale from a free tier for prototyping to enterprise agreements with custom rate limits, SLAs, and support.
Every API returns clean JSON, plus purpose-built AI tooling: an MCP server for coding assistants and an llms.txt index for RAG pipelines and agents.
Who builds on it
From early-stage startups to enterprises and institutions: wallets embedding swaps and portfolio views, fintechs adding on-chain trading, trading platforms consuming market data, and infrastructure providers running on managed RPC — all operating under real-world load with production reliability.
