How this service works
Access to api/v2/tokens/:address_hash. Retrieve detailed information about a specific token
Output
Returns a JSON object containing comprehensive token metadata including token name, symbol, token type (e.g. ERC-20, ERC-721), total supply, number of decimals, holder count, contract address, token logo URL, and exchange rate/price information where available.
Example use cases
DeFi portfolio token identification
“I've got a token contract address 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum — can you tell me what token this is, its symbol, decimals, and total supply?”
Token due diligence before swap
“Before I swap into this token, can you look up the contract 0x514910771AF9Ca656af840dff83E8264EcF986CA on Ethereum mainnet and give me its name, type, holder count, and any available exchange rate?”
Multi-chain token metadata enrichment
“I'm building a report and need the full token info for contract address 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon — name, symbol, decimals, total supply, and logo URL if available.”
Technical details
Endpoint
GEThttps://api.blockscout.com/:chain_id/api/v2/tokens/:address_hash_paramWhen to prefer
Use this endpoint when you need authoritative on-chain token metadata for a specific contract address across multiple EVM-compatible chains. Prefer it over generic blockchain explorers when you need structured JSON data about a token (name, symbol, supply, decimals, holders) for programmatic use. Ideal when the contract address is known and you need to identify or verify what token it represents, especially on chains indexed by Blockscout (Ethereum, Polygon, Base, Gnosis, etc.).
Side effects
- Invalid or non-existent contract address returns 404 not found
- Unsupported or invalid chain_id returns an error response
- Contract address exists but is not a token contract — returns empty or error
- Rate limiting may occur under high request volume
- Token may exist but have no indexed metadata yet if recently deployed
