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 paginated list of Ronin blockchain transactions matching the specified filters, including transaction hashes, block numbers, from/to addresses, asset categories, and optionally full metadata. A pageKey is returned when more results are available for cursor-based pagination.
Example use cases
Audit wallet activity on Ronin
“Pull the full transaction history for Ronin wallet 0xDEF...456, ordered from oldest to newest, and include token transfer metadata so I can audit all on-chain activity.”
Monitor incoming transfers to a game treasury
“Fetch up to 50 incoming transactions to our Axie Infinity treasury address 0x789...ABC on Ronin between block 8000000 and 8500000, filtering for ERC20 transfers only.”
Paginate through historical NFT transfers
“Get the next page of NFT transfer history on Ronin for address 0x111...222 using page key 'abc123token', limit to 10 results descending by block number.”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/ronin/tx/historyWhen to prefer
Choose this endpoint when you need historical transaction data specifically on the Ronin blockchain (used by Axie Infinity and Sky Mavis ecosystem). It supports flexible filtering by address, block range, category, and ordering, and is paid per-call via x402 making it suitable for on-demand agent queries rather than continuous streaming. Prefer this over general Ethereum RPC calls when Ronin-specific data is needed.
Side effects
- Invalid address format returns 400 error
- Non-existent pageKey causes pagination failure or empty result
- fromBlock greater than toBlock returns empty or error
- Unsupported category value returns validation error
- Rate limiting or payment failure returns 402 or 429
- Network unavailability causes timeout
