How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns a paginated list of on-chain transactions on the opBNB network, including sender/receiver addresses, block numbers, transaction hashes, asset transfer details, and optionally metadata. A pageKey is included when more results are available for the next page.
Example use cases
Wallet activity audit for compliance
“Get me the full transaction history for opBNB address 0xDEF...456, from block 1000000 to 2000000, sorted oldest-first, including metadata so I can audit what this wallet has been doing.”
DeFi portfolio tracker refresh
“Fetch the most recent 25 transactions for my opBNB wallet 0xABC...789, sorted newest first, and include token transfer metadata so I can update my portfolio dashboard.”
Smart contract interaction history
“Show me all ERC-20 token transfers sent from 0x111...AAA to contract 0x222...BBB on opBNB, excluding zero-value transactions, paginated with up to 100 results.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/opbnb/tx/history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical transaction data specifically on the opBNB (Optimistic BNB) Layer-2 network. Prefer it over generic explorers when you need programmatic, paginated, filterable access to wallet or contract transaction history with metadata, block-range filters, and sort control — especially in agent workflows that process on-chain activity automatically via pay-per-call access.
Side effects
- Invalid address format returns a 400 error
- Invalid block range (toBlock less than fromBlock) causes an error
- Unknown category values may be rejected or silently ignored
- Exceeding maxCount limits may result in truncated results or errors
- Network downtime or RPC issues may return 500 errors
- Expired or invalid x402 payment token causes a 402 payment required error
