How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns a list of token transfer records for the specified wallet on the Humanity protocol, each containing details such as transaction hash, block number, from/to addresses, token contract, value, and asset metadata. Supports pagination via a pageKey for large result sets.
Example use cases
Audit wallet token activity
“Show me all token transfers for wallet 0xDEADBEEF on the Humanity network from block 500000 to block 1000000, sorted ascending, up to 50 results — I need to audit its activity.”
Track specific token contract transfers
“Get all transfers of the token at contract 0xTOKENCONTRACT for wallet 0xMYWALLET on Humanity, sorted descending, and give me the first 25 results.”
Paginate through full transfer history
“I already fetched the first page of token transfers for wallet 0xABC on Humanity — can you get the next page using pageKey xyz789, same settings, max 100 records?”

Endpoint
POSThttps://synapse-api-brown.vercel.app/api/humanity/token/transfersWhen to prefer
Use this endpoint when you need on-chain token transfer history specifically for the Humanity protocol and want block-range filtering, contract address filtering, and pagination in a single pay-per-call API with no subscription required. Prefer this over general blockchain explorers when integrating into an automated agent workflow that needs structured JSON output.
Side effects
- Invalid wallet address format returns an error
- Unknown or malformed contract address silently returns no results
- Block range too large may time out or return partial results
- Invalid pageKey causes pagination error
- Missing required 'owner' field returns validation error
- Network or provider downtime results in 502/503 error
