How this service works

High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.

Output

Returns a paginated list of token transfer events on the Monad blockchain associated with the specified owner address, including transfer amounts, contract addresses, block numbers, and transaction hashes. A pageKey is included in the response when more results are available.

Example use cases

Audit wallet token activity

“Pull all token transfers for Monad address 0xDEADBEEF... between blocks 10000 and 20000 — I need to audit every token that came in or went out, sorted from newest to oldest.”

Track specific token contract transfers

“Get me the transfer history on Monad for contract address 0xMONADTOKEN... for the wallet 0xMYWALLET..., showing up to 50 results in ascending block order.”

Paginate through large transfer history

“Continue fetching token transfers on Monad for wallet 0xLARGEWALLET... — use page key abc123xyz to get the next batch of up to 200 results in descending order.”
