Example use cases
Wallet token activity audit

Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/degen/token/transfersWhen to prefer
Choose this endpoint when you need paginated, filterable token transfer history for a specific wallet address across one or more ERC-20 contracts, especially when you need block-range scoping or need to iterate through large transfer histories. Prefer this over generic blockchain explorers when you need structured JSON output suitable for downstream agent processing and are comfortable with pay-per-call pricing.
Side effects
- Invalid or malformed wallet address returns an error
- Unknown or unsupported contract address silently returns empty results
- Invalid block range (fromBlock > toBlock) may return error or empty set
- Missing required 'owner' field causes request failure
- pageKey from a different query context returns unexpected results
- Rate limiting or payment failure (x402) blocks access
