How this service works
Read ERC-20 symbol, name, decimals, and raw total supply for up to ten contract addresses using live eth_call requests.
Output
Returns an array of token metadata objects, each containing the token's logo URL, full name, ticker symbol, contract address, and decimal precision for the requested contracts on the specified chain.
Example use cases
DeFi portfolio token enrichment
“I have a list of Ethereum token contract addresses from my wallet — 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48, 0x6B175474E89094C44Da98b954EedeAC495271d0F, and 0xdAC17F958D2ee523a2206206994597C13D831ec7 — can you fetch the name, symbol, logo, and decimals for all of them at once?”
Token symbol resolution for DEX UI
“We're building a decentralized exchange interface and need the names, symbols, and logos for these five Base network token contracts: 0x111..., 0x222..., 0x333..., 0x444..., 0x555... — grab their metadata in one shot.”
Blockchain security due diligence enrichment
“I'm running due diligence on several token contracts on Ethereum and need to verify their official names, symbols, and decimal precision — the addresses are 0xaaa..., 0xbbb..., and 0xccc.... Pull the metadata for all three.”

Endpoint
GEThttps://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/token_metadata_bulkWhen to prefer
Use this endpoint when you need to resolve multiple token contract addresses to human-readable metadata in a single API call, especially in DeFi, portfolio, or security workflows on Ethereum or other supported chains. It is more cost-efficient than making individual token metadata lookups when processing lists of 2+ contracts.
Side effects
- Invalid or non-existent contract address returns missing or null fields for that entry
- Unsupported blockchain network returns an error or empty results
- Malformed address array causes a 400 bad request
- Network or upstream data source downtime returns 503 or timeout
- Payment failure via x402 returns 402 Payment Required
