Endpoint
POSThttps://synapse-api-brown.vercel.app/api/metis/token/transfersWhen to prefer
Choose this endpoint when you need to query token transfer history specifically on the Metis L2 blockchain network. It is ideal for auditing wallet activity, tracking ERC-20 token flows, or performing on-chain analytics on Metis with fine-grained block range and pagination control. Prefer this over generic blockchain explorers when you need programmatic, pay-per-call access with structured JSON output.
Side effects
- Invalid or malformed wallet/contract address returns an error
- Block range too large may result in timeout or truncated results
- Invalid pageKey causes pagination failure
- Missing required owner or contractAddresses field may return empty or error
- Non-existent block numbers return empty results
- Rate limiting or payment failure (x402) blocks the request
