Alchemy
Blockchain developer platform with RPC APIs, data APIs, and developer tooling.
Alchemy is a blockchain infrastructure platform for developers that provides APIs and managed services for building applications across more than 100 blockchains. It addresses the need for reliable access to onchain data and transaction execution, covering JSON-RPC calls, token prices and balances, NFT data, transfers, portfolio information, websockets, and webhooks.
The platform includes dedicated single-tenant clusters, rollup deployment, Solana RPC and gRPC, validator services, gasless transaction sponsorship, and bundler and paymaster APIs. Cortex is presented as an intelligent layer supporting the developer platform. An agentic stack connects coding agents through the Alchemy MCP server, CLI, and agent skills, with support for MCP clients such as Claude Code and Cursor. Security measures include TLS for API calls, regular penetration testing, DDoS protection, role-based access controls, and a bug bounty program.
Alchemy is aimed at developers and teams building fintech, payments, DeFi, NFT, and AI-agent applications. Pricing includes a free tier with request limits, app and webhook allowances, and monthly compute units, alongside a pay-as-you-go plan with higher request rates and additional apps and webhooks.
