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
A JSON object keyed by address containing reputation metadata and scoring signals for each queried blockchain address, indicating trust level or risk flags associated with each address.
Example use cases
Pre-transfer wallet safety check
“Before I send any ETH to 0xAbC123...def456, can you look up its reputation score on Blockscout to make sure it's not flagged as a scam or malicious address?”
DeFi protocol address verification
“I want to interact with this DeFi contract at 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D — can you check its reputation via Blockscout metadata to see if it's trustworthy?”
Batch suspicious address screening
“I have a few addresses from an airdrop claim — 0xdeadbeef...1234 and 0xcafe...5678 — can you check their Blockscout reputation scores to see if any of them are flagged?”
Technical details
Endpoint
GEThttps://api.blockscout.com/services/metadata/api/v1/reputationWhen to prefer
Choose this endpoint when you need a quick reputation or risk signal for one or more blockchain addresses before performing transactions, whitelisting wallets, or due-diligence checks. It is particularly useful for cross-chain address screening since Blockscout indexes multiple networks. Prefer this over general blockchain explorers when you specifically need structured reputation metadata rather than raw transaction history.
Side effects
- Invalid or malformed address string returns an error or empty result
- Address not found in Blockscout's metadata database returns empty scores
- Rate limiting or payment failure (x402) blocks the request
- Unsupported chain addresses may return no reputation data
- Network timeout if Blockscout metadata service is unavailable
