How this service works
Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.
Output
A JSON object containing the token's full name, ticker symbol, contract address, network (e.g. 'base'), and decimal precision (e.g. 6 for USDC). Example: {name: 'USD Coin', symbol: 'USDC', address: '0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913', network: 'base', decimals: 6}.
Example use cases
Identify unknown Base token contract
“I found this contract address on Base: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — can you tell me what token it is, its symbol, and how many decimal places it has?”
DeFi integration token decimals check
“Before I build a swap integration, can you fetch the decimals and symbol for this ERC-20 token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base so I format amounts correctly?”
Portfolio tracker token enrichment
“I'm tracking a wallet on Base that holds a token at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — what's the full name and symbol of that token?”
Technical details
Endpoint
GEThttps://volkov.evgeny.m2.fvds.ru/pay/token?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, pay-per-request ERC-20 token metadata resolution on the Base network without committing to a full RPC node subscription or heavy blockchain indexer. Ideal for agents that occasionally need to enrich a contract address with human-readable token info (name, symbol, decimals) and want micropayment billing via USDC on Base (x402 protocol) rather than API keys or subscriptions.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Address not on Base network may return wrong or no data
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Network timeout or server unavailability on the host domain
- Non-ERC-20 contract address may return malformed or incomplete metadata
