Alchemy

Alchemy is a Web3 infrastructure platform for onchain application development, offering RPC APIs, data APIs, and developer tools covering more than 100 blockchains. Its official website claims that over 150,000 teams worldwide use its services, processing trillions of dollars in transactions annually. The platform emphasizes high reliability and performance, claiming to make applications 2.5 times faster and 5 times more reliable, and has routed trillions of queries. Alchemy offers gasless transactions, price/balance/NFT/transaction history queries, Solana-specific RPC and gRPC support, onchain event streams, dedicated single-tenant infrastructure, and other products. At the same time, the platform has launched a development stack for AI agents, including the Alchemy MCP server (160+ blockchain tools), CLI, and skill packs, supporting MCP clients such as Claude Code and Cursor, and can be connected without an API key. Its customers include Fortune 500 companies and numerous developer teams.

About this tool

Alchemy is a Web3 infrastructure platform for onchain application development, providing APIs, developer tools, and blockchain infrastructure, supporting more than 100 blockchains. Developers can build and scale decentralized applications through its RPC API, data API, and various tools.

Purpose Alchemy is mainly used for the development and scaling of onchain financial applications and decentralized applications, providing underlying capabilities such as connecting to blockchain networks, querying data, sending transactions, processing payments, and managing wallets.

Main capabilities

  • RPC API: node access services across 100+ blockchains.
  • Data API: obtain prices, balances, NFTs, and complete transaction history in a single call.
  • Agentic Payments: a unified platform for payment applications, agents, stablecoins, and marketplaces.
  • Gasless transactions: reduce user friction and increase transaction volume by paying gas fees on behalf of users.
  • Solana-specific support: provides RPC, gRPC, validators, and other services.
  • Onchain event streams: push onchain events to applications in real time.
  • Dedicated Infra: fully managed, single-tenant infrastructure for special workloads.
  • Tool stack for AI agents: Alchemy MCP server (hosted, providing 160+ blockchain tools), CLI (each API can be used as a command; install once to query chains, transfer funds, and set up MCP), skill packs (teach AI coding agents to correctly use Alchemy APIs).
  • Agent registration process: agents can self-serve wallet authentication, with no forms and no API keys.
  • Agent compatibility: out-of-the-box support for Claude Code, Cursor, and any MCP client.
  • Agent financial tools: wallets that allow agents to create, fund, and trade independently; endpoints that accept payments from any agent; cards that can be spent anywhere cards are accepted.

How to use Developers can sign up for Alchemy and start using its APIs and tools for free. The platform provides CLI installation and MCP server access, supporting AI coding agents to connect to blockchains through the Alchemy MCP server, CLI, and skill packs. The official website mentions "Get started for free." Specific installation commands, code examples, and pricing details are not currently provided in the supplied materials.

Use cases Suitable for decentralizedfinance (DeFi), payment applications, stablecoin banks, consumer fintech, prediction markets, NFT applications, trading platforms, and other onchain financial products. It is also suitable for scenarios where AI agents interact with blockchains, execute payments, manage wallets, and so on.

Limitations The materials do not provide specific pricing plans, free quota limits, regional availability, technical limitations, or other information. The platform's official website calls itself "secure rails for the next generation of financial applications" and emphasizes that 150,000+ teams already use it, but does not provide detailed limitations beyond specific performance metrics.
