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 list of transaction records for the specified address(es) on the Soneium network, including transfer type, block number, from/to addresses, value, and optional metadata. Results are paginated with a pageKey for continuation.
Example use cases
Wallet audit for a Soneium account
“Give me the full transaction history for Soneium address 0xDeadBeef... going back to block 1000000, sorted from newest to oldest, and include metadata for each transaction.”
Token transfer monitoring for DeFi app
“Fetch all ERC-20 token transfers received by 0xMyDeFiContract... on Soneium, up to 50 results, and skip any zero-value transactions.”
On-chain activity pagination for analytics
“I need to page through Soneium transaction history for 0xUserWallet... — start from pageKey abc123, get 100 results in ascending order so I can reconstruct the full activity timeline.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/soneium/tx/historyWhen to prefer
Use this endpoint when you need historical transaction data specifically on the Soneium network and want fine-grained filtering by address, block range, category, and sort order. Prefer it over general-purpose blockchain explorers when you need programmatic, paginated access with metadata in a pay-per-call model without API key setup.
Side effects
- Invalid or unrecognized address format returns an error
- Invalid block range (fromBlock > toBlock) causes a bad request
- Unsupported category filter values return no results or error
- Missing required address fields may return an empty or error response
- Network timeout if Soneium node is slow or unavailable
- Payment failure via x402 if USDC balance is insufficient
