How this service works
Pay-per-call data API for AI agents. No API key, no account, no signup — pay USDC on Base (eip155:8453) per request; free /api/meta lists all 22 endpoints. One call each: web page to LLM-ready text and link previews; China A-share quotes and limit-up pool; Chinese text and pinyin; Base/Ethereum on-chain reads (address, token, ERC-20 balances, tx, blocks, transfer history, gas price in USD); NFT records (collection, owner, and ipfs:// tokenURI resolved through public gateways); full-page screenshots; email verification without sending mail; ENS forward/reverse resolution; smart-contract due diligence (ABI, verified source, proxy); token security facts (owner, renounced ownership, paused, bytecode capability selectors); domain dossier (RDAP, DNS, TLS certificate, HTTP facts, hosting network).
Output
A JSON object with ok=true, the token's symbol (e.g. 'USDC'), its contract address, whether EIP-3009 is supported, the number of decimals, a flag confirming it is a contract, and the total supply as a string. Returns ok=false with an error on invalid or non-contract addresses.
Example use cases
EIP-3009 compliance check before gasless transfer
“Before I set up a gasless transfer flow, can you check if the token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base supports EIP-3009 transferWithAuthorization?”
Verify token decimals for amount calculation
“I need to display a human-readable balance — can you fetch the decimals and symbol for the Base mainnet token at 0x4200000000000000000000000000000000000006?”
Confirm a new token listing's on-chain supply
“We're listing a new token — can you pull the total supply and confirm it's actually a contract at address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base mainnet?”
Technical details
Endpoint
GEThttps://api.zlovev.com/api/chain/tokenWhen to prefer
Choose this endpoint when you need on-chain Base mainnet token metadata (symbol, decimals, EIP-3009 support, total supply) without registering for an account or holding an API key — ideal for AI agents that pay per call via USDC on Base using the x402 protocol. Prefer alternatives like Alchemy or Infura if you need batch lookups, historical data, or multi-chain support.
Side effects
- Address not 0x-prefixed or not 20 bytes — validation error
- Address is an EOA (non-contract) — returns is_contract=false with no token fields
- Network issues with Base RPC — timeout or 5xx
- Missing required 'address' query parameter — 400 error
- Payment not settled — 402 Payment Required if x402 flow fails
