Blockscout API is the REST interface of the open-source block explorer, serving address, transaction, token and contract data on EVM chains without a key.
The information on this page was compiled from the provider's own sources, but the record has not been through full editorial review. Verify access conditions and limits against the provider's current documentation. Records in this state are not indexed by search engines.
Our review criteriaCatalog notes to consider when evaluating the integration, in addition to the provider documentation.
Blockscout runs a separate instance per chain rather than a single multi-chain host; the Test Lab default is the Ethereum instance (eth.blockscout.com). Switch the base URL for another chain, for example base.blockscout.com. Projects that self-host expose the same REST schema, so an integration is portable. Public endpoints were verified without a key on 2026-08-08; run your own instance for heavy use.
