# Get logs

`GET /logs`

Retrieve logs for the given transaction(s). Corresponds to the <a href="/chifra/chaindata/#chifra-logs">chifra logs</a> command line.

## Query parameters

- `transactions` string[], required
- `emitter` string[]
- `topic` string[]
- `articulate` boolean
- `chain` string
- `noHeader` boolean
- `cache` boolean
- `decache` boolean
- `fmt` string

## Response `200`

returns the requested data

- object
  - `data` union[] — Produces <a href="/data-model/other/#function">Function</a>, <a href="/data-model/chaindata/#log">Log</a>, <a href="/data-model/other/#message">Message</a> or <a href="/data-model/other/#parameter">Parameter</a> data. Corresponds to the <a href="/chifra/chaindata/#chifra-logs">chifra logs</a> command line.
