Etherscan vs The Graph

Etherscan's API exposes the same account balances, transactions, contract source, and gas-tracker data shown on the block explorer, addressed to Ethereum mainnet and its testnets through a single query-parameter-based endpoint. Calls against the older V1 endpoint now return a deprecation notice pointing at the documented V2 migration, so new integrations should build against V2 directly. Free-tier keys cover light use, with paid plans unlocking higher rate limits.

The Graph indexes onchain data into open GraphQL subgraphs that any client can query through its hosted Gateway, covering Ethereum and dozens of other networks without a per-chain node integration. The Gateway requires a bearer token issued from Subgraph Studio, billed on a usage-based model with a free monthly query allowance before paid billing applies. Every query and response travels as GraphQL over HTTPS.
