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 asset transfers and transactions on the Arbitrum network, including transaction hashes, block numbers, asset categories (ERC-20, ERC-721, internal, external, etc.), token metadata (symbol, decimals, name), from/to addresses, values, and a pageKey for continued pagination.
Example use cases
Audit DeFi wallet activity
“Show me all transactions on Arbitrum from wallet 0xDeFi...wallet in descending order, max 50, with full token metadata included — I want to review recent DeFi activity.”
Monitor incoming transfers to a contract
“Fetch all incoming transactions to smart contract address 0xContract...456 on Arbitrum between block 100000000 and 110000000, categorized by asset type, and exclude zero-value transfers.”
Paginate through historical token transfers
“I already have the first page of Arbitrum tx history for address 0xWallet...789 — continue fetching the next page using pageKey 'abc123xyz' in ascending order, up to 25 results.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/arbitrum/tx/history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need historical transaction or asset transfer data specifically on the Arbitrum L2 network, with support for block-range filtering, pagination, category filtering (ERC-20, ERC-721, internal, external), and metadata enrichment. Prefer this over generic block explorers when you need structured, machine-readable data for agent workflows or on-chain auditing.
Side effects
- Invalid or missing address returns empty result or 400 error
- Invalid block range (fromBlock > toBlock) returns error
- Unrecognized category values may be ignored or return 400
- pageKey from a different query context causes unexpected results
- Rate limiting or payment failure returns 402
- Arbitrum node unavailability returns 503 or timeout
