How this service works
Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data
Output
Returns a JSON array of chain objects, each containing the chain's ID, display name, icon URL, and the Blockscout explorer URL for that chain within the specified cluster.
Example use cases
Discover networks in a DeFi cluster
“Can you pull up all the blockchain networks that belong to Blockscout cluster 'defi-top-chains' so I can see which chains my portfolio spans?”
Cross-chain dapp network coverage check
“I'm building a multichain dapp — use Blockscout to list every chain in cluster 'evm-compatible' so I know which networks I need to support.”
Populate chain selector UI from cluster
“Fetch all chains under Blockscout cluster 'layer2-networks', sorted ascending, so I can populate a dropdown in my cross-chain dashboard.”
Technical details
Endpoint
GEThttps://api.blockscout.com/services/multichain/api/v1/clusters/%7Bcluster_id%7D/chainsWhen to prefer
Use this endpoint when you need to programmatically enumerate which specific blockchain networks belong to a Blockscout multichain cluster, especially for populating UI selectors, validating chain coverage, or building cross-chain dashboards. Prefer this over generic chain-list endpoints when your workflow is already oriented around Blockscout cluster IDs and you need explorer URLs alongside chain metadata.

- Invalid sort/order query parameter values may return an error or default ordering
- Network timeouts or service unavailability return 5xx errors
- Payment failure (insufficient USDC balance for x402 protocol) blocks access
