Example use cases
Verify token metadata before DeFi integration
“Before I add this token to our liquidity pool, can you look up the full metadata for 0x4200000000000000000000000000000000000006 on Base — name, symbol, decimals, total supply, and holder count?”
Check USD rate of a Base token
“What's the current USD price of the token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, and how many holders does it have?”
Audit unknown token contract
“Someone sent me tokens from contract 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb — can you tell me what token this is, its symbol, decimals, and total supply on Base?”

Endpoint
GEThttps://api.x-402.online/v1/chain/token?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need comprehensive ERC-20 token metadata — including holder count and USD rate — from the Base blockchain in a single call, without needing to query multiple on-chain RPCs or aggregators. Ideal for AI agents that need to enrich token data quickly and cheaply ($0.005/call) without managing wallet infrastructure or blockchain node access.
Side effects
- Contract address not found on Base — returns empty or error response
- Token not indexed by Blockscout — USD rate or holder count may be null or absent
- Malformed address format — API may return a validation error
- Token exists but USD rate unavailable — rate field returned as null
- Network or upstream Blockscout outage — request times out or returns 5xx
