# eth_getFilterLogs | Tempo

> Tempo API method that returns an array of all logs matching the filter with the given ID. eth_getFilterLogs on Tempo via Chainstack.

Tempo API method that returns an array of all logs matching the filter with the given ID. Unlike `eth_getFilterChanges`, this returns all matching logs, not just new ones since the last poll.

## Parameters

* `filterId` — the filter ID returned from `eth_newFilter`

## Response

* `result` — array of log objects matching the filter:
  * `address` — contract address that emitted the log
  * `topics` — array of indexed log parameters
  * `data` — non-indexed log parameters
  * `blockNumber` — block number containing the log
  * `blockHash` — hash of the block
  * `transactionHash` — hash of the transaction that emitted the log
  * `transactionIndex` — index of the transaction in the block
  * `logIndex` — position of the log in the block
  * `removed` — `true` if the log was removed due to a chain reorganization
