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 paginated JSON object containing a list of address items (string identifiers), an array of matching blockchain addresses, and next-page pagination parameters (pageSize and pageToken) for iterating through further results.
Example use cases
Identify labeled exchange addresses on Ethereum
“Pull up all addresses tagged as 'exchange' on Ethereum (chain ID 1) from Blockscout — show me the first 20 with their labels.”
Find dapp contract addresses by slug
“I need to find the contract addresses associated with the slug 'uniswap' across blockchain networks using Blockscout's metadata — can you fetch those?”
Paginate through known addresses on a chain
“Get me the next page of tagged blockchain addresses on chain ID 137 from Blockscout using this page token 'abc123', 10 results per page.”
Technical details
Endpoint
GEThttps://api.blockscout.com/services/metadata/api/v1/addressesWhen to prefer
Choose this endpoint when you need to look up labeled, tagged, or named blockchain addresses (such as exchanges, dapps, or verified contracts) across multiple chains using Blockscout's curated metadata. It is ideal for enriching raw on-chain data with human-readable address tags, filtering addresses by chain or tag type, or paginating through large address sets. Prefer alternatives if you need full transaction history, token balances, or real-time on-chain state.
Side effects
- Invalid or unsupported chainId returns empty results or 400 error
- Missing required 'type' or 'method' fields in input causes schema validation failure
- Unknown slug returns empty items array
- Expired or invalid pageToken results in pagination errors or repeated first page
- Rate limiting or payment failure returns 402 payment required
