Example use cases
Wallet token activity audit
“Show me all token transfers for wallet address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e, sorted from oldest to newest, up to 50 results.”

Endpoint
POSThttps://synapse-api-brown.vercel.app/api/tempo/token/transfersWhen to prefer
Choose this endpoint when you need to retrieve historical token transfer events for a specific wallet address on supported blockchain networks, especially when you need filtering by block range or specific ERC-20/ERC-721 contract addresses. It is well-suited for portfolio auditing, on-chain forensics, and DeFi activity tracking where paginated token movement history is required.
Side effects
- Invalid or malformed wallet address returns an error or empty result set
- Non-existent contract address yields empty transfers array
- Invalid block number format causes a 400-level error
- Expired or invalid pageKey causes pagination to fail or restart
- Exceeding maxCount limits may silently truncate results
- Network or rate limit errors may return 429 or 5xx responses
