Endpoint
POSThttps://synapse-api-brown.vercel.app/api/kaia/token/transfersWhen to prefer
Use this endpoint when you need on-chain token transfer history specifically on the Kaia blockchain for a given wallet or set of contracts. It is distinct from general EVM chain transfer APIs and is purpose-built for Kaia network data. Prefer it over generic blockchain explorers when you need programmatic, paginated, filterable transfer data accessible via pay-per-call without a subscription.
Side effects
- Invalid or malformed owner address returns an error or empty result
- Invalid block numbers (fromBlock/toBlock) may return an error or unexpected range
- Exceeding max supported maxCount may be silently capped or return an error
- Invalid contractAddress format causes request failure
- Missing required owner field results in a validation error
- Payment failure via x402 protocol blocks the request
