Tool detail
Alchemy · JSON-RPC call (eth_*, alchemy_*)
Executes a single Ethereum-style JSON-RPC call (eth_* or alchemy_* method) against Alchemy's node for a chosen network.
Categories: Onchain data
Use when
- call a specific eth_* JSON-RPC method (balance, block, receipt, etc.) on a supported chain
- call an Alchemy-specific alchemy_* enhanced RPC method
Not for
- not a REST convenience wrapper - caller must know the exact RPC method and params
- not NFT-specific lookups - use the NFT API v3 endpoint for that
Inputs
POST JSON-RPC body: { method: string (eth_*/alchemy_*), params: array } (required); path parameter network selects the target chain (required)
