Endpoint
POSThttps://synapse-api-brown.vercel.app/api/linea/tx/historyWhen to prefer
Use this endpoint when you need detailed asset transfer history specifically on the Linea L2 blockchain network. Prefer this over generic Ethereum history endpoints when the target addresses are on Linea. Supports rich filtering by address pair, block range, asset category, and sort order, making it suitable for auditing, analytics, or DeFi agent workflows on Linea.
Side effects
- Invalid or malformed Ethereum address returns an error
- Block range too large may result in timeout or truncated results
- Invalid pageKey causes pagination failure
- Unsupported category value returns an error
- Network outage on Linea RPC causes empty or failed response
- Exceeding maxCount limits may truncate results silently
