The world of Web3 development is evolving rapidly, and 1inch Labs is stepping up to empower builders with a powerful new tool: the beta release of the 1inch Developer Portal. This cloud-based SaaS (Software-as-a-Service) platform offers developers access to cutting-edge APIs that streamline the creation of innovative decentralized applications.
Designed for speed, reliability, and ease of use, the 1inch Developer Portal delivers battle-tested infrastructure used across 1inch’s own flagship products — including the 1inch dApp and 1inch Wallet. With this launch, developers can now leverage the same high-performance tools that have powered one of the industry’s most trusted DeFi platforms since 2019.

Why Build on the 1inch Developer Portal?
The 1inch Developer Portal isn’t just another API suite — it’s a comprehensive solution engineered for real-world performance and developer efficiency. Here’s why it stands out in the competitive Web3 landscape:
✅ Proven & Battle-Tested Solutions
Every API available on the portal has been rigorously tested within live 1inch products. This means developers aren’t working with theoretical tools — they’re using infrastructure refined through years of real transaction volume and user demand.
✅ Trusted by Industry Leaders
Top-tier Web3 projects like MetaMask, Trust Wallet, and Ledger already integrate 1inch APIs into their ecosystems. This widespread adoption speaks volumes about the reliability and security of the underlying technology.
✅ High Availability & Low Latency
With a 99% uptime SLA, the platform ensures consistent access for mission-critical applications. More importantly, its ultra-low latency design delivers some of the fastest response times in the market — crucial for time-sensitive swaps and real-time data retrieval.
✅ Deep Liquidity Aggregation
Thanks to its integration with over 100,000 liquidity sources across multiple blockchains, the 1inch Swap API consistently finds optimal trade routes. This depth ensures better pricing and higher execution success rates for end users.
✅ Intuitive Developer Experience
From clear documentation to detailed analytics dashboards, every aspect of the portal is built with developer experience in mind. Real-time request tracking, upgrade alerts, and modular endpoints make onboarding fast and efficient.
✅ Flexible Access Options
Promising startups can apply for dedicated enterprise endpoints at no cost during early stages — a significant advantage for bootstrapped teams looking to validate their ideas without infrastructure overhead.
Core API Solutions Available
The 1inch Developer Portal offers a full-stack suite of APIs covering key aspects of decentralized finance and blockchain interaction. Each service is optimized for performance, accuracy, and scalability.
1inch Swap API
At the heart of the platform lies the Swap API, powered by Pathfinder — an advanced routing algorithm that identifies the most efficient path for token swaps across multiple chains. By splitting trades across various liquidity pools and DEXs, Pathfinder ensures users receive the best possible rates while minimizing gas costs through highly optimized contract calls.
This API supports self-custodial trading, meaning users retain control of their funds throughout the entire process — a critical feature for security-conscious applications.
1inch Spot Price API
Get real-time market prices for any supported cryptocurrency based on actual available liquidity. Ideal for price display widgets, trading bots, or risk analysis tools, this API provides accurate spot pricing without delays or distortions.
1inch Balance API
Quickly retrieve wallet balances and spending allowances for ERC-20 tokens and native assets. This lightweight API reduces development time when building dashboards or transaction interfaces that require real-time balance checks.
1inch Token API
Search for any token by name, symbol, or contract address. Whether you're integrating new tokens dynamically or verifying contract details, this API returns verified metadata such as decimals, name, symbol, and logo URI — helping prevent spoofing and improving UX.
1inch Transaction Gateway API
Broadcast transactions securely to the blockchain using either public or private modes. The private relay option offers MEV (Miner Extractable Value) protection, shielding transactions from front-running bots — a vital feature for large trades or sensitive operations.
1inch Portfolio API
Analyze wallet activity across Ethereum, BNB Chain, and Polygon. This API extracts actionable insights from on-chain data, enabling performance tracking, portfolio rebalancing tools, and market trend analysis — all through a single, easy-to-integrate endpoint.
1inch Orderbook API
Built on top of the 1inch Limit Order Protocol, this API enables developers to create and manage limit orders directly within their apps. Users can set custom prices and monitor order status in real time — bringing centralized exchange-like functionality to decentralized platforms.
1inch NFT API
Retrieve comprehensive data on all NFTs held in a user’s wallet on Ethereum and Gnosis Chain. This includes metadata, ownership history, and collection details — perfect for building NFT marketplaces, galleries, or analytics platforms.
Subscription Plans: Free & Enterprise Tiers
Currently, two main plans are available:
- Free Plan: Ideal for prototyping and non-commercial use cases. Offers limited requests per second (RPS), allowing developers to test core functionalities before scaling.
- Enterprise Plan: Designed for production-grade applications requiring high throughput. Fully customizable with higher RPS limits, dedicated support, and tailored endpoint configurations.
Future plans — including Professional and Commercial tiers — are expected to roll out soon, offering intermediate options for growing projects.
⚠️ Important Notice: The public version of the 1inch API will be deprecated on August 18. Developers currently using it are strongly encouraged to migrate to the new Developer Portal before then to avoid service disruption.

Frequently Asked Questions (FAQ)
Q: Is the 1inch Developer Portal free to use?
A: Yes, there is a free tier available for non-commercial use and prototyping. It includes basic access to all APIs with rate-limited requests per second.
Q: What blockchains are supported by the APIs?
A: The platform supports major EVM-compatible chains including Ethereum, BNB Chain, Polygon, Optimism, Arbitrum, and more — with ongoing expansion to additional networks.
Q: How does the Swap API find the best prices?
A: It uses the proprietary Pathfinder algorithm, which scans dozens of DEXs and liquidity sources across chains to split trades optimally and minimize slippage and gas fees.
Q: Can I protect my transactions from MEV attacks?
A: Yes. The Transaction Gateway API includes a private relay mode that prevents front-running by broadcasting transactions directly to validators.
Q: Are there SDKs or code examples available?
A: Comprehensive documentation includes sample code in JavaScript, Python, and other languages. SDKs are also under active development.
Q: How do I migrate from the old public API?
A: Visit the Developer Portal to generate new API keys and update your endpoints. Migration guides and changelogs are provided to ensure a smooth transition.
Final Thoughts
The launch of the 1inch Developer Portal marks a significant milestone in lowering barriers to Web3 innovation. By offering robust, scalable, and well-documented APIs — all built on proven infrastructure — 1inch is enabling developers to focus on creativity rather than complexity.
