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 Kaia blockchain transactions matching the specified filters, including sender/receiver addresses, block numbers, transaction categories, and optional metadata. A pageKey is provided for fetching subsequent pages when more results exist.
Example use cases
Wallet audit for a Kaia account
“Get me all the transactions for Kaia address 0xDEF456... between block 1000000 and 1500000, sorted newest first, and include transaction metadata.”
Token transfer history monitoring
“Fetch the incoming token transfers to my Kaia wallet 0x789GHI... for the last 100 transactions, categorized as ERC20, and skip any zero-value entries.”
Paginated on-chain activity review
“I need to page through the full transaction history of Kaia address 0xJKL012... starting from the beginning — give me the first 25 records ascending, then I'll use the pageKey to get more.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/kaia/tx/historyWhen to prefer
Use this endpoint when you specifically need transaction history on the Kaia blockchain network and want pay-per-call pricing at $0.01 USDC with no subscription required. Prefer this over general-purpose blockchain explorers when you need programmatic, filterable access to Kaia tx history with pagination, block range filtering, and category-based filtering in a single API call.
Side effects
- Invalid address format returns an error response
- Block range too large may time out or return partial results
- Unknown category values may be ignored or cause validation errors
- Missing both fromAddress and toAddress may return an error or empty result
- pageKey expiry may require restarting pagination from the beginning
