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
A list of token transfer records on the Worldchain network, each containing details such as sender and receiver addresses, token contract address, transfer amount, block number, and transaction hash, with optional pagination key for fetching subsequent pages.
Example use cases
Audit wallet token activity
“Show me all token transfers in and out of wallet 0x1234abcd... on Worldchain for the last 1000 blocks, sorted from oldest to newest.”
Track specific ERC-20 movements
“Get me every transfer of the token at contract 0xTokenABC... on Worldchain for the address 0xMyWallet..., up to 100 results.”
Paginate through large transfer history
“I'm pulling transfer history for 0xBigWallet... on Worldchain — I already have the first page, here's my pageKey, give me the next batch of 25 transfers in descending order.”

Endpoint
POSThttps://synapse-api-brown.vercel.app/api/worldchain/token/transfersWhen to prefer
Choose this endpoint when you need on-chain token transfer history specifically on the Worldchain network, with support for filtering by wallet, contract address, and block range. Prefer this over generic blockchain explorers when you need structured JSON output suitable for programmatic consumption by an AI agent, and when pay-per-call pricing ($0.01 USDC) via x402 is acceptable.
Side effects
- Invalid or malformed owner address returns an error
- Unknown or invalid contract address in contractAddresses array
- Invalid block number format for fromBlock or toBlock
- pageKey expired or invalid causes pagination failure
- maxCount exceeding API limits returns an error or truncated result
- Network or upstream indexer unavailability causes a 500-level error
