title: Remote Read API
sort_rank: 7
---
NOTE: This is not currently considered part of the stable API and is subject to change even between non-major version releases of Prometheus.
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/main/prompb/remote.proto).
Request are made to the following endpoint.
```
/api/v1/read
```
## Samples
This returns a message that includes a list of raw samples matching the
requested query.
## Streamed Chunks
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.
