Integrating 1inch was remarkably smooth—their well-documented API abstracted complex routing logic beautifully. With superior liquidity aggregation across EVM chains and consistent sub-second response times, 1inch enabled us to deliver enterprise-grade swap functionality without the overhead of building our own infrastructure.

Questions? Answers.
What are 1inch APIs and how can I use them?
1inch APIs give you plug-and-play access to DeFi—swap tokens, fetch prices, track balances, and connect to top chains like Ethereum, Solana, BNB Chain, Unichain, Base, Sonic, and more.
Why choose a multi-chain API over single-chain tools?
A multi-chain API provides a unified interface to multiple blockchain networks, reducing complexity and accelerating development. Instead of integrating separate tools and maintaining distinct codebases for Ethereum, or other chains, developers can use one API layer for consistent access across ecosystems. This not only streamlines cross-chain applications but also future-proofs products as user demand shifts between networks.
What does an API SLA typically cover in Web3?
An API Service Level Agreement (SLA) generally defines performance and reliability commitments. In Web3, this usually covers availability (e.g., 99.9% uptime guarantees), latency (maximum response times for queries), throughput (assured request volumes per second), and support and escalation procedures (response times if issues occur).
How do I get an API key on 1inch Business?
