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 matching the specified address(es), block range, and category filters. Each record includes transaction details such as block number, hash, from/to addresses, asset, value, and optionally full metadata. A pageKey is returned for cursor-based pagination through large result sets.
Example use cases
Wallet activity audit for DeFi user
“Show me all transactions sent from 0xDeF...456 between block 18000000 and 19000000, sorted oldest to newest, including metadata — I want to audit what this wallet has been doing.”
Portfolio tracker inflow monitoring
“Fetch the 50 most recent inbound transactions to my wallet 0xGHI...789, including ERC-20 transfers, and exclude any zero-value ones so I can track meaningful deposits.”
On-chain forensics for suspicious address
“Get me the full transaction history between wallet 0xAAA...111 as sender and 0xBBB...222 as receiver, descending order, with metadata, so I can trace what funds moved between them.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/degen/tx/historyWhen to prefer
Use this endpoint when you need historical on-chain transaction data for one or two specific wallet addresses, optionally filtered by block range and transaction category. It is ideal for auditing wallet activity, building portfolio trackers, or performing on-chain forensics. Prefer this over general blockchain explorers when you need programmatic, paginated, pay-per-call access without API key friction and when working across 57+ supported networks.
Side effects
- Invalid or malformed address format returns an error
- Block range too large may result in timeout or truncated results
- Unknown or unsupported category value may return empty results
- Missing required address fields results in a validation error
- pageKey expiry or mismatch causes pagination failure
- Network not supported returns an error response
- Rate limiting or payment failure (x402) blocks the call
