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 list of transaction records for the specified address or block range on the Katana network, including transaction hashes, block numbers, sender/receiver addresses, values, categories, and optional metadata. A pagination key is included for fetching subsequent pages when there are more results.
Example use cases
Wallet activity audit for DeFi user
“Show me all transactions sent from 0xDeFi...wallet on Katana between block 1000 and block 5000, sorted oldest to newest, and include metadata so I can see what each one was for.”
Smart contract incoming transfer monitor
“Fetch the most recent 50 transactions sent to my smart contract at 0xContract...456 on Katana, in descending order, filtering out zero-value transfers.”
Paginated history for analytics pipeline
“Get up to 100 on-chain transactions involving address 0xUser...789 on Katana starting from block 200, and give me a page key so I can continue fetching the next batch.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/katana/tx/history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical transaction data specifically on the Katana network, require pagination support for large result sets, need to filter by block range or transaction category, or want to audit wallet activity with optional metadata. Prefer this over generic blockchain explorers when you need programmatic, pay-per-call access integrated into an agent workflow.
Side effects
- Invalid or malformed address returns an error or empty result
- Block range out of bounds returns an empty array
- Invalid category filter may return no results or an error
- Missing required address fields may cause a 400 bad request
- Payment failure via x402 results in a 402 response blocking data access
- Exceeding maxCount limits may truncate results silently
