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 on-chain transactions matching the specified address filters, block range, and category criteria. Each record includes transaction hash, block number, from/to addresses, value, asset, category, and optionally full metadata. A pageKey is returned when more results are available for pagination.
Example use cases
Wallet audit for compliance review
“Get me all on-chain transactions sent from 0xDEF...456 to 0xABC...123 between block 17000000 and 18500000, sorted oldest to newest, with full metadata included.”
DeFi portfolio transaction tracker
“Fetch the 50 most recent token transfer transactions for my wallet 0x111...999, excluding any zero-value ones, and include metadata so I can see what tokens were moved.”
Paginated transaction history export
“I need to page through the full transaction history for address 0xAAA...BBB — start from the beginning, give me 100 records at a time in ascending order, and use the pageKey from the last response to get the next batch.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/humanity/tx/history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical on-chain transaction records for a specific address or address pair, especially when you require pagination, block-range filtering, category filtering (e.g. ERC20, internal, external), or metadata-enriched results. Prefer this over generic RPC calls when you want structured, queryable transaction history without parsing raw block data yourself. Well-suited for auditing, portfolio analysis, and compliance workflows.
Side effects
- Invalid or malformed address returns a 400 error
- Block range too large may cause timeout or truncated results
- Invalid pageKey causes pagination error or restart
- Unsupported category value returns empty results or error
- Network unavailable returns 503 or gateway error
- Exceeding maxCount limits may return partial results
