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 Avalanche transactions matching the specified filters, including transaction hashes, block numbers, from/to addresses, asset categories, and optional metadata. A pageKey is returned when more results are available for subsequent pagination calls.

Example use cases

Wallet activity audit for compliance

“Get me all transactions sent from Avalanche wallet 0xDef456... between block 30000000 and 31000000, sorted oldest to newest, including token transfers and internal transactions — I need to audit all on-chain activity for a compliance review.”

DeFi portfolio tracker refresh

“Fetch the most recent 50 Avalanche transactions for my wallet 0xAbc789..., including metadata, so I can update my DeFi portfolio tracker with the latest on-chain activity.”

ERC-20 transfer monitoring for a dApp

“Get all ERC-20 and ERC-721 token transfer transactions on Avalanche to address 0x111aaa... from block 29000000 onwards, excluding zero-value transfers, and page through all results.”

When to prefer

Choose this endpoint when you need structured, paginated Avalanche transaction history with fine-grained filtering by address, block range, and asset category. Prefer over raw RPC calls when you need metadata enrichment or multi-category filtering in a single request.

Side effects

Invalid address format returns a 400 error
Block range too large may result in timeout or truncated results
Unknown category values may be silently ignored or cause a 400
Missing both fromAddress and toAddress may return an error or empty result
pageKey expiry can cause pagination gaps if not used promptly
Payment failure via x402 returns 402 before any data is returned
