Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/adi/token/transfersWhen to prefer
Use this endpoint when you need paginated, filterable token transfer history for a specific wallet owner on supported blockchain networks, especially when you need to scope results by block range or specific token contracts. Prefer this over general blockchain explorers when you need programmatic, pay-per-call access without API key management overhead.
Side effects
- Invalid or malformed owner address returns an error or empty result
- Block range too large may time out or return partial results
- Invalid contract address format causes a validation error
- Missing owner field may result in a 400 bad request
- pageKey mismatch or expiry causes pagination to fail
- Network congestion or upstream provider outage causes 5xx errors
