How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

Example use cases
Wallet activity audit for compliance
“Show me all transactions sent from 0xDeFi...456 on Unichain between block 1000000 and 1500000, sorted oldest first, including metadata — I need a full audit trail of outgoing activity.”
DeFi portfolio transaction tracker
“Fetch the most recent 50 incoming transfers to my contract at 0xVault...789 on Unichain, filtering to ERC-20 category only and excluding zero-value transfers.”
Paginated history for on-chain analytics
“Get the next page of Unichain transaction history for address 0xTrader...321, using pageKey 'abc123xyz', descending order, with a max of 100 results.”

Endpoint
POSThttps://phantom-api-omega.vercel.app/api/unichain/tx/history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need historical on-chain transaction data specifically for the Unichain network, want fine-grained filtering by address direction, block range, and asset category, and need pagination support for large result sets. Prefer it over generic block explorers when you need structured JSON output suitable for programmatic processing by an AI agent.
Side effects
- Invalid address format returns a 400 or empty result
- Block range too large may timeout or return partial results
- Unknown pageKey causes pagination to restart or error
- Unsupported category string silently ignored or errors
- Rate limiting or payment failure (x402) blocks the request
- Unichain node unavailability causes 503 or timeout
