Tokenvault — ERC-20 Token Metadata on Base
x402
Tokenvault — ERC-20 Token Metadata on Base is a paid API for AI agents from oraclepost.higgsfield.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-18).
Returns live ERC-20 token metadata (name, symbol, decimals, total supply) from a contract on Base by making direct eth_call reads with no cache or third-party API.

How this service works
ERC-20 token metadata on Base, read live from the contract: name, symbol, decimals and total supply. Pass ?token=0x… (the token contract address). One eth_call set, no third-party API, no cache.
Output
Returns the four standard ERC-20 metadata fields read live via eth_call from the Base chain: token name (string), symbol (string), decimals (uint8), and total supply (uint256). Data is real-time with no caching layer or third-party intermediary.
Example use cases
Identify unknown token contract
“I found this contract address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base — can you tell me what token it is, its symbol, and how many decimals it uses?”
Verify token total supply for due diligence
“What is the live total supply of the token at 0x4200000000000000000000000000000000000006 on Base? I want the number read directly from the contract, not from a third-party index.”
Enrich DeFi dashboard with token details
“For each of these Base token addresses I'm tracking, pull the name, symbol, and decimals directly from the contract so I can label them correctly in my portfolio view — start with 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb.”
Technical details
Endpoint
GEThttps://oraclepost.higgsfield.app/api/premium/tokenWhen to prefer
Choose this endpoint when you need authoritative, uncached ERC-20 metadata (name, symbol, decimals, total supply) for a specific contract address on the Base network. It is ideal when freshness matters, when you cannot trust indexed or cached sources, or when verifying a contract's identity directly from the chain. Prefer it over generic block explorers or token registries when you need programmatic access to raw on-chain metadata without third-party data dependencies.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty/reverted call result
- Contract on a network other than Base will not resolve correctly
- Malformed 0x address format causes a validation or RPC error
- Token contract that does not implement standard ERC-20 metadata functions (name/symbol/decimals) may return partial or no data
- RPC node unavailability on Base causes a timeout or network error
