GET /query v1

Execute InfluxQL query (v1-compatible)

Executes an InfluxQL query to retrieve data from the specified database.

This endpoint is compatible with InfluxDB 1.x client libraries and third-party integrations such as Grafana. Use query parameters to specify the database and the InfluxQL query.

Parameters

Query parameters
chunked boolean
If true, the response is divided into chunks of size chunk_size.
chunk_size integer
The number of records that will go into a chunk. This parameter is only used if chunked=true.
Default: 10000
db string <InfluxQL>
The database to query. If not provided, the InfluxQL query string must specify the database.
pretty boolean
If true, the JSON response is formatted in a human-readable format.
q required string
The InfluxQL query string.
epoch string
Formats timestamps as unix (epoch) timestamps with the specified precision instead of RFC3339 timestamps with nanosecond precision.
u string
Username for v1 compatibility authentication. When using Basic authentication or query string authentication, InfluxDB 3 ignores this parameter but allows any arbitrary string for compatibility with InfluxDB 1.x clients.
p string
Password for v1 compatibility authentication. For query string authentication, pass a database token with write permissions as this parameter. InfluxDB 3 checks that the p value is an authorized token.
rp string
Retention policy name. Honored but discouraged. InfluxDB 3 doesn’t use retention policies.
Header parameters
Accept string

The content type that the client can understand.

If text/csv is specified, the Content-type response header is application/csv and the response is formatted as CSV.

Returns an error if the format is invalid or non-UTF8.

Allowed values: application/json , application/csv , text/csv
Default: application/json
Authorization string

Authorization header for token-based authentication. Supported schemes:

  • Bearer AUTH_TOKEN - OAuth bearer token scheme
  • Token AUTH_TOKEN - InfluxDB v2 token scheme
  • Basic <base64-encoded USERNAME:AUTH_TOKEN> - Basic authentication (username is ignored)
