Query API

Query historical contract logs filtered by address, topic, and block range

Returns indexed contract logs (events) for the requested chain and block range. Standard eth_getLogs semantics, plus multi-chain dispatch, pagination, and optional event-signature decoding via decodeLogs: true.

Pass blockchain and either a block range (fromBlock / toBlock) or a time range (fromTimestamp / toTimestamp). Scope by address (single or array of contracts) and / or topics (nested arrays matching eth_getLogs topic filter semantics). Paginate with pageSize (default 1000, max 10000) and pageToken.

Part of the Query API product (700 compute units per call, $0.00007 at base rate).
