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
A list of token transfer objects including sender, recipient, token contract address, amount, block number, transaction hash, and asset type. Supports cursor-based pagination via pageKey for iterating through large result sets.
Example use cases
Wallet token activity audit
“Show me every token transfer in and out of wallet 0xAbCd...1234 on Ethereum from block 17000000 to 18000000, sorted oldest to newest.”
DeFi portfolio inflow tracking
“Fetch up to 50 incoming ERC-20 transfers to my address 0xDeFi...5678, filtering to just USDC and USDT contract addresses, sorted descending by block.”
Smart contract transfer monitoring
“Get all token transfer events involving the contract 0xA0b8...eB48 (USDC) for my wallet 0xUser...9999 starting from block 19000000, paginate through all results.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/ethereum/token/transfersWhen to prefer
Use this endpoint when you need historical token transfer data for a specific Ethereum wallet or contract, especially when you require block-range filtering, sorting, or paginated traversal of large transfer histories. Prefer this over general blockchain explorers when you need structured, machine-readable output suitable for downstream analysis or automation.
Side effects
- Invalid Ethereum address format returns a 400 or error response
- Invalid block number format causes query failure
- Exceeding maxCount limits or missing required owner field returns validation error
- Contract address array with non-checksummed addresses may return empty results
- Payment failure via x402 results in 402 response before data is returned
