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 transaction records on the Sonic blockchain matching the specified filters, potentially including metadata such as token details, block numbers, timestamps, sender/receiver addresses, and a pageKey for continuation.
Example use cases
Wallet audit for Sonic address
“Show me the full transaction history for Sonic address 0xDeF456... sorted from oldest to newest, including all token transfer categories with metadata.”
Block-range activity report
“Fetch all transactions on the Sonic chain between block 1000000 and block 1050000 involving address 0x789Ghi..., excluding zero-value transfers, and give me up to 100 results.”
Paginated tx feed for monitoring
“Get the next page of Sonic transactions for address 0xJkL012... using page key 'abc-page-key-xyz', sorted descending, so I can continue where I left off.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/sonic/tx/history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical transaction data specifically on the Sonic blockchain network, with flexible filtering by address, block range, and category. Prefer this over general EVM history APIs when the target chain is Sonic and you need pay-per-call pricing without a subscription.
Side effects
- Invalid or missing address formats return an error response
- Unsupported block range or out-of-bounds blocks may return empty results or an error
- Invalid category values may cause a 400 bad request
- Exceeding maxCount limits or passing an invalid pageKey may cause pagination errors
- Payment failure via x402 protocol results in a 402 response blocking data access
