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
A paginated list of on-chain transactions matching the specified address(es), block range, and category filters. Each transaction record typically includes block number, transaction hash, from/to addresses, asset type, value, and optional metadata. A pageKey is returned when more results are available for subsequent pagination calls.
Example use cases
Wallet audit for compliance review
“Give me the full transaction history for wallet 0x1234...abcd from block 18000000 to 19000000, sorted oldest-first, including token transfers — I need to audit all inbound and outbound activity.”
DeFi portfolio activity tracker
“Fetch the last 100 transactions for my wallet 0xDEAD...BEEF, categorized by token transfers and internal transactions, with full metadata so I can see what DeFi protocols I've interacted with.”
Detect incoming payments to a contract
“Show me all non-zero-value transactions sent to contract address 0xABCD...5678 in descending order, up to 50 results — I want to see recent payments hitting that contract.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/plasma/tx/historyWhen to prefer
Choose this endpoint when you need historical on-chain transaction data for a specific wallet or contract address, especially when you need filtering by block range, category, or direction. It is particularly suited for auditing wallet activity, monitoring incoming payments, or building transaction histories for DeFi analytics. Prefer this over generic RPC calls (e.g., eth_getTransactionByHash) when you need multi-transaction queries with metadata enrichment and pagination support.
Side effects
- Invalid or malformed address returns a 400 error
- fromBlock or toBlock values outside available indexed range may return empty results
- Exceeding maxCount limits may truncate results without warning
- Missing required address fields results in a validation error
- Network congestion or indexer lag may cause stale or incomplete data
- Payment failure (x402) blocks the request entirely
