It covers Cloud, CDN, DNS, WAAP, DDoS Protection, Object Storage, Streaming, and FastEdge services. version: '2026-05-11T15:10:30.328297+00:00' servers: - url: https://api.gcore.com security: - APIKey: [] tags: - name: CDN service description: Information about the current state of the CDN service in your account. x-displayName: CDN service - name: CDN resources x-displayName: CDN resources - name: Origins x-displayName: Origins - name: Rules description: >- Rules allow to set up custom settings for certain file types or paths. By default, the rule inherits all options values from the related CDN resource. Each option in rule settings can be in one of the following states: - **Inherit** - Option is not added to the rule. Option inherits its value from the CDN resource settings. In this case, the option value is **null**. - **ON** - Option is added to the rule and enabled. Option values configured in the rule will override values from the CDN resource settings. - **OFF** - Option is added to the rule and disabled. Option will be turned off. x-displayName: Rules - name: Rule templates x-displayName: Rule templates - name: SSL certificates x-displayName: SSL certificates - name: Let's Encrypt certificates x-displayName: Let's Encrypt certificates - name: CA certificates x-displayName: CA certificates - name: CDN activity logs description: |- Get the history of users requests to CDN.

This information does not contain all possible sets of fields and restricted by time. To receive full data, use Logs Uploader. x-displayName: Log viewer - name: Logs uploader description: >- Logs uploader allows you to upload logs with desired format to desired storages. Consists of three main parts: - **Policies** - rules that define which logs are uploaded and how they are uploaded. - **Targets** - destinations where logs are uploaded. - **Configs** - combinations of logs uploader policies, targets and resources to which they are applied. x-displayName: Logs uploader - name: Tools x-displayName: Tools - name: CDN Statistics description: >- Consumption statistics is updated in near real-time as a standard practice. However, the frequency of updates can vary, but they are typically available within a 24-hour period. Exceptions, such as maintenance periods, may delay data beyond 24 hours until servers resume and fill in the missing statistics. x-displayName: Statistics - name: Advanced analytics description: >- Advanced analytics allows to get statistics about unique visitors, traffic, and requests for countries, directories, browsers, devices, and operation systems for up to 90 days starting from today. Advanced analytics API is based on the [GraphQL framework](https://graphql.org/). Advanced analytics API has one single endpoint: https://api.gcore.com/cdn/advanced/v2/query You can pass the query parameters as a JSON object in the payload of a POST request to this endpoint. You can use curl to make requests to the Advanced analytics API. Alternatively, you can use a GraphQL client to construct queries and pass requests to the Advanced analytics API. You can write queries in GraphQL much like in SQL: specify the data set (CDN resource), the metrics to retrieve (such as unique visitors and traffic), and filter or group by dimensions (for example, a country). x-displayName: Advanced analytics - name: Origin shielding x-displayName: Origin shielding - name: IP addresses list x-displayName: IP addresses list - name: Purge history x-displayName: Purge history paths: /cdn/sslData/{cert_id}/force-retry: post: tags: - Let's Encrypt certificates summary: Force retry issuance of Let's Encrypt certificate description: >- Force retry issuance of Let's Encrypt certificate if the previous attempt was failed. operationId: force-retry-issuance-of-lets-encrypt-certificate parameters: - in: path name: cert_id description: Let's Encrypt certificate ID. required: true schema: type: integer responses: '201': description: Successful.
