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 list of token transfer events on the Citrea network for the specified owner address, optionally filtered by contract addresses and block range. Each record typically includes sender, recipient, token contract, amount, block number, and transaction hash.
Example use cases
Audit wallet token activity
“Can you pull up all the token transfers for my Citrea wallet 0xDEADBEEF... from block 500000 to 600000, sorted from oldest to newest, up to 100 results?”
Track specific token contract movements
“I need to see every transfer of the token at contract address 0xTOKEN123 on Citrea for my address 0xMYWALLET... — show me the latest 25, sorted descending.”
Paginate through large transfer history
“I was browsing token transfers for 0xUSER456 on Citrea and hit a page limit — can you continue from where I left off using pageKey 'abc-page-key-xyz' and grab the next 50 transfers?”
