----------------------------------------------------------------------
`POST /api/v1/check-access` {#post--api-v1-check-access}
: A service to check if account and/or related project has the access
to specified queue.
Request JSON Object:
- **login** (*string*) – account id
- **queue** (*string*) – queue id
- **pid** (*string*) – project id, not required if querying projectless queue
- [200 OK](http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.2.1)
– no error
**Example request**:
curl -i -H "Content-Type:application/json" -X POST \
--data '{"pid":"DD-13-5","login":"johnsm","queue":"qfat"}' \
https://scs.it4i.cz/api/v1/check-access
**Example response**:
HTTP/1.1 200 OK
Content-Type: application/json
"OK Access granted for regular queue."
`GET /api/v1/dedicated-time/`(*cluster\_type*) {#get--api-v1-dedicated-time-cluster_type}
: Returns list of times dedicated for HPC maintainance. It is not
possible to use HPC services during maintainance.
Query Parameters:
- **all** – returns all dedicated times for all clusters
- **salomon** – returns all times just for salomon cluster
- **anselm** – returns all times just for anselm cluster
- **active** – returns dedicated times for all clusters which are
- **planned** – returns dedicated times for all clusters which are
now active or scheduled in the future
Status Codes:
OK](http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.2.1)
– no error

`POST /api/v1/it4ifree/`(*login*) {#post--api-v1-it4ifree-login}
: A service to check resources of the projects on which the account
participate. If the calculation run on 1 cpu core during 1 hour, it
consumes 1 core-hour from the project resources. However, some
calculations (or their placement) can be cheaper. Actual consumed
core-hours are reduced by a cheaping factor and then deduct from the
project resources. See
<https://docs.it4i.cz/salomon/resources-allocation-policy/#normalized-core-hours-nch>
for more details about so-called normalized core-hours. The json
response contains two parts:
- `me` – data from projects, where the account has access
- `me_as_pi` – data from projects, where the account is PI (primary investigator)
- **login** (*string*) – account id
- **it4ifreetoken** (*string*) – token
- **login** (*string*) – account id
- **pid** (*string*) – project id
- **pi\_login** (*string*) – account id which is PI
- **days\_left** (*string*) – days to the end of project,
`---` if project is inactive or not yet
started
- **free** (*int*) – free core-hours which can be still consumed
- **total** (*int*) – total core-hours assigned to the project
- **used** (*int*) – actual consumed core-hours
- **used\_with\_factor** (*int*) – consumed normalized core-hours
- **used\_by\_me** (*int*) – core-hours consumed by the account
- **used\_by\_me\_with\_factor** (*int*) – normalized core-hours
- **corehours** (*int*) – core-hours consumed by the account
- **core\_hours\_with\_factor** (*int*) – normalized core-hours
consumed by the account
