How this service works
ERC-20 token metadata (name, symbol, decimals, total supply) for any token contract across major EVM chains. On-chain reference data for agents.
Output
A JSON object containing the token's name (e.g. 'USD Coin'), symbol (e.g. 'USDC'), number of decimals (e.g. 6), and total supply string for the specified ERC-20 contract address on the requested EVM network.
Example use cases
Example prompt
“What's the name, symbol, decimals, and total supply of the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum?”
Technical details
Endpoint
POSThttps://x402.valkyry.fr/token-info?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve an ERC-20 token contract address to its human-readable metadata (name, symbol, decimals, total supply) on Ethereum or major L2s, and you want a pay-per-call model without API key signup. Prefer this over on-chain RPC calls when you lack direct node access, or over aggregator APIs when you want minimal-cost micropayment-gated lookups.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty metadata
- Unsupported network name results in a validation error
- Contract address exists but has no standard ERC-20 interface (returns partial or null fields)
- Network RPC unavailable leads to timeout or 503 error
- Payment not processed (x402 payment failure) results in 402 response before data is returned
