Example use cases
Wallet activity audit on Berachain
“Show me the full transaction history for Berachain wallet 0xAbC...123, up to 50 results, ordered from oldest to newest, and include token metadata so I can see what assets moved.”
Monitor incoming transfers to a contract
“Get all incoming transactions to Berachain contract address 0xDef...456 starting from block 1000000 to block 2000000, excluding zero-value transfers, and include metadata.”
Paginate through large wallet history
“I already fetched the first page of transactions for Berachain address 0x789...abc — now continue from pageKey 'abc123xyz' and get the next 25 results in descending order.”

Endpoint
POSThttps://synapse-api-brown.vercel.app/api/berachain/tx/historyWhen to prefer
Use this endpoint when you need on-chain transaction history specifically for the Berachain network with flexible filtering by address, block range, asset category, and pagination. Prefer this over generic blockchain explorers when you need structured, programmatic access to Berachain tx data with metadata, and when pay-per-call pricing via x402 fits your usage pattern better than a subscription.
