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
Returns a JSON object with: ok (boolean success flag), from (sender address), to (recipient address), hash (transaction hash), block (block number), status ('success' or error string), fee_eth (fee in ETH), fee_usd (fee in USD as number), gas_used (integer), value_eth (ETH value transferred), and confirmations (integer count).
Example use cases
Verify a USDC payment on Base
“I just sent a USDC payment on Base — the transaction hash is 0xabc123...def456. Can you confirm it went through and tell me the status and how many confirmations it has?”
Audit gas costs for a Base transfer
“Can you fetch the details for Base transaction 0x9f8e7d...6c5b4a and tell me exactly how much gas was used and what the fee was in both ETH and USD?”
Confirm recipient of an on-chain transfer
“I need to verify who received the funds in Base transaction 0x1a2b3c...4d5e6f — can you look it up and give me the from and to addresses along with the value transferred?”
Technical details
Endpoint
GEThttps://api.zlovev.com/api/chain/txWhen to prefer
Choose this endpoint when you need a pay-per-call, no-signup way to verify or inspect a specific Base mainnet transaction by hash — particularly useful for AI agents that need to confirm payment receipts, audit gas costs, or validate on-chain transfers without maintaining API keys or accounts. Prefer this over block explorer scraping when you need structured JSON output suitable for downstream processing.
Side effects
- Invalid or malformed transaction hash returns an error response
- Transaction hash not found on Base mainnet returns ok:false or 404
- Network congestion may delay confirmation count updates
- Hash for a transaction on a different chain (e.g. Ethereum mainnet) will not be found
- Missing required 'hash' query parameter causes a validation error
