path Parameters
context_id
required
string
Example: be8bb2e3-c3d6-4098-89f4-572ff976ba9a

path Parameters
context_id
required
string
Example: be8bb2e3-c3d6-4098-89f4-572ff976ba9a

Request Body schema: application/json
required
project_id
string <uuid>
Deprecated

Deprecated - Use "restriction_type" and "restriction_value" instead.

The project ID to use for a project restriction. This is mutually exclusive with restriction_type and restriction_value and implies restriction_type is "project".

restriction_type
string
Enum: "project" "expression"

Type of the restriction.

restriction_value
string

Value used to evaluate the restriction. If the restriction_type is project, this will be the project UUID. If the restriction_type is expression, this will be the expression rule.

Usage

Endpoints related to organization usage exports.

The Usage API is an API provided by CircleCI to customers to access all of their usage data on CircleCI. It contains all the metadata (org, project, pipeline, workflow, and job dimensions) as well as credit consumption data. It is provided at the near lowest level of granularity (at the job run level).

Restrictions

  • Max result set size of 100MB
  • Query timeout of 4 hours.
  • Max date window of 32 days
  • 13 months of historical data is available
  • No PII is surfaced in the Usage API (e.g. email address, Github login name)
  • The POST endpoint can only be queried up to (i.e. is rate limited to) 10 times per hour per org
  • The GET endpoint can only be queried up to (i.e. is rate limited to) 10 times per hour per org
  • To increase performance the API can generate multiple CSV files that need to be merged after download

organization_name The org name
organization_created_date The date (UTC) that the org was created
