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 transactions on the Mantle blockchain matching the specified filters. Each transaction record includes details such as transaction hash, block number, from/to addresses, value, and optionally extended metadata like asset details, category, and timestamps. A pageKey may be returned for fetching subsequent pages.

Example use cases

Audit wallet activity on Mantle

“Show me all transactions sent from my Mantle wallet 0xDEADBEEF... between block 1000000 and 1050000, sorted newest first, and include transaction metadata.”

Track incoming transfers to a smart contract

“Get up to 50 incoming transactions to the Mantle contract address 0xCONTRACT123... with full metadata, excluding any zero-value transfers.”

Paginate through full transaction history

“Fetch the next page of Mantle transaction history for address 0xMYWALLET456... using page key 'abc123token', return results in ascending order.”

When to prefer

Choose this endpoint when you need on-chain transaction history specifically for the Mantle L2 network. It supports filtering by address, block range, transaction category, and value, with pagination support for large result sets. Prefer this over generic Ethereum RPC calls when you need structured, enriched transaction data on Mantle without running your own node.

Side effects

Invalid address format returns a 400 or error response
Unknown or malformed pageKey causes pagination failure
fromBlock greater than toBlock returns empty results or error
Requesting unsupported category types may return empty or error
Rate limiting or payment failure (x402) blocks the request
Very large block ranges may time out or return truncated results
