Event Logs of One Block on an EVM Chain

evmrpc/logs

The event logs emitted in ONE block, chosen by block hash, optionally only those of one contract address and matching the first topics (topic 0 is the event signature hash). Up to 200 logs are returned, with the total count. One block at a time on purpose: public nodes disagree wildly on how wide a block range they will serve. Read from public nodes that offer no SLA and can be slow, throttled or a block behind; a failing node is replaced by another operator's automatically. Served by Eden Engine; not an official product of any chain or node operator.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "evmrpc/logs" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "evmrpc/logs" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "evmrpc/logs", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "evmrpc/logs", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
