# eth\_getLogs - Ethereum

This method returns all logs matching the given criteria across a block range — the most direct way to query historical events without creating a persistent filter. Ideal for one-off historical queries, indexer backfills, and any workflow where the filter criteria change per query.

## Parameters

| Parameter | Type   | Required | Description                                                   |
| --------- | ------ | -------- | ------------------------------------------------------------- |
| `filter`  | object | Yes      | Filter criteria — same shape as `eth_newFilter` filter object |

## Response Parameters

| Parameter | Type            | Description                                                            |
| --------- | --------------- | ---------------------------------------------------------------------- |
| `jsonrpc` | string          | JSON-RPC protocol version ("2.0")                                      |
| `id`      | string          | Request identifier matching the request                                |
| `result`  | array of object | Matching log entries in ascending order by (`blockNumber`, `logIndex`) |

## Use Cases

* **Indexer Backfill**: Iterate through historical block ranges to backfill contract events into an indexer database
* **Wallet Activity History**: Query all Transfer events for a specific address (as sender or receiver) across a block range
* **Analytics Queries**: Aggregate Swap events, deposits, or governance actions over time windows
* **Airdrop Snapshotting**: Retrieve all Transfer events for a token up to a snapshot block to compute historical holders

## Error Handling

| Error Code | Message                                            | Description                                               |
| ---------- | -------------------------------------------------- | --------------------------------------------------------- |
| -32602     | Invalid params                                     | Filter is malformed or block range is invalid             |
| 403        | Request block range exceeds the limit(1500 blocks) | Block range too wide — narrow the range or use pagination |
| -32603     | Internal error                                     | Node failed to retrieve matching logs                     |
