 # Remote Read API
 
-This is not currently considered part of the stable API and is subject to change

-## Format overview
-
-The API response format is JSON. Every successful API request returns a `2xx`
-status code.
-
-Invalid requests that reach the API handlers return a JSON error object
-and one of the following HTTP response codes:
-
-- `400 Bad Request` when parameters are missing or incorrect.
-- `422 Unprocessable Entity` when an expression can't be executed
-  ([RFC4918](https://tools.ietf.org/html/rfc4918#page-78)).
-- `503 Service Unavailable` when queries time out or abort.
-
-Other non-`2xx` codes may be returned for errors occurring before the API
-endpoint is reached.
-
-An array of warnings may be returned if there are errors that do
-not inhibit the request execution. All of the data that was successfully
-collected will be returned in the data field.
-
-The JSON response envelope format is as follows:
-
-```
-{
-  "status": "success" | "error",
-  "data": <data>,
-
-  // Only set if status is "error". The data field may still hold
-  // additional data.
-  "errorType": "<string>",
-  "error": "<string>",
-
-  // Only if there were warnings while executing the request.
-  // There will still be data in the data field.
-  "warnings": ["<string>"]
-}
-```
-
-Generic placeholders are defined as follows:
-
-* `<rfc3339 | unix_timestamp>`: Input timestamps may be provided either in
-[RFC3339](https://www.ietf.org/rfc/rfc3339.txt) format or as a Unix timestamp
-in seconds, with optional decimal places for sub-second precision. Output
-timestamps are always represented as Unix timestamps in seconds.
-* `<series_selector>`: Prometheus [time series
-selectors](basics.md#time-series-selectors) like `http_requests_total` or
-`http_requests_total{method=~"(GET|POST)"}` and need to be URL-encoded.
-* `<duration>`: [Prometheus duration strings](basics.md#time_durations).
-For example, `5m` refers to a duration of 5 minutes.
-* `<bool>`: boolean values (strings `true` and `false`).
-
-Note: Names of query parameters that may be repeated end with `[]`.

-## Remote Read API
 
 This API provides data read functionality from Prometheus. This interface expects [snappy](https://github.com/google/snappy) compression.
 The API definition is located [here](https://github.com/prometheus/prometheus/blob/master/prompb/remote.proto).

 These streamed chunks utilize an XOR algorithm inspired by the [Gorilla](http://www.vldb.org/pvldb/vol8/p1816-teller.pdf)
 compression to encode the chunks. However, it provides resolution to the millisecond instead of to the second.
