Include your API key in the `Authorization` header: ``` Authorization: Bearer sk_live_your_api_key_here ``` ## Rate Limits - **Live keys**: 1,000 requests per minute - **Test keys**: 100 requests per minute Both key prefixes access the same organization data. The prefix selects the rate-limit bucket. Successful authenticated responses include rate limit headers: - `X-RateLimit-Limit`: Maximum requests per window - `X-RateLimit-Remaining`: Requests remaining in current window - `X-RateLimit-Reset`: Unix timestamp when the window resets ## Pagination Canary-native list endpoints use ID cursors and the standard `data`/`meta` envelope. MaintainX-compatible request endpoints use their compatibility response wrappers and encoded offset cursors. Follow each operation's response schema. Native list responses include: - `data`: Array of items - `meta.pagination.cursor`: Cursor for the next page (if `has_more` is true) - `meta.pagination.has_more`: Whether more items exist Use the cursor value in your next request: `?cursor=` servers: - url: https://api.oncanary.com/v1 description: Production - url: http://localhost:3000/api/v1 description: Local Development security: - bearerAuth: [] tags: - name: Meters description: Meters track equipment usage and readings - name: Meter Readings description: Record and retrieve meter readings - name: Work Orders description: Maintenance work orders - name: Work Requests description: Requests that can be reviewed and converted into work orders - name: Work Request Portals description: Public request portal configuration - name: Assets description: Equipment and machinery - name: Locations description: Physical places where assets, parts, and meters are assigned - name: Parts description: Spare parts and inventory records - name: Identifiers description: Scannable identifiers for assets, locations, and parts - name: Custom Fields description: Typed custom-field definitions shared by maintenance resources paths: /assets/{id}: get: tags: - Assets summary: Get an asset description: Retrieve a single asset by ID operationId: getAsset parameters: - $ref: '#/components/parameters/id' responses: '200': description: Asset details content: application/json: schema: $ref: '#/components/schemas/AssetResponse' '401': $ref: '#/components/responses/Unauthorized' '403': $ref: '#/components/responses/Forbidden' '404': $ref: '#/components/responses/NotFound' '429': $ref: '#/components/responses/RateLimited' components: parameters: id: name: id in: path required: true description: Resource ID schema: type: string schemas: AssetResponse: allOf: - $ref: '#/components/schemas/SingleResponse' - type: object properties: data: $ref: '#/components/schemas/Asset' SingleResponse: type: object required: - data - meta properties: data: type: object meta: type: object required: - request_id - api_version properties: request_id: type: string api_version: type: string Asset: type: object required: - id - name - description - asset_type - asset_types - status - criticality - serial_number - manufacturer - model - year - location_id - parent_asset_id - sub_asset_count - deleted_at - image_url - created_at - updated_at properties: id: type: string name: type: string description: type: - string - 'null' asset_type: $ref: '#/components/schemas/AssetCurrentType' asset_types: type: array readOnly: true description: Active organization-defined asset type assignments items: $ref: '#/components/schemas/AssetTypeAssignment' status: $ref: '#/components/schemas/AssetStatus' criticality: $ref: '#/components/schemas/AssetCriticality' serial_number: type: - string - 'null' manufacturer: type: - string - 'null' model: type: - string - 'null' year: type: - integer - 'null' location_id: type: - string - 'null' parent_asset_id: type: - string - 'null' readOnly: true sub_asset_count: type: integer minimum: 0 readOnly: true deleted_at: type: - string - 'null' format: date-time readOnly: true image_url: type: - string - 'null' extraFields: $ref: '#/components/schemas/ExtraFields' created_at: type: string format: date-time updated_at: type: string format: date-time ProblemDetails: type: object description: RFC 7807 Problem Details required: - type - title - status - detail - request_id - code example: type: https://api.oncanary.com/errors/validation_error title: Validation Error status: 400 detail: Request validation failed request_id: req_01JAY8FVDM6CH4R3X9Q2T7K5NP code: validation_error properties: type: type: string format: uri title: type: string status: type: integer detail: type: string request_id: type: string code: type: string validation_errors: type: array items: type: object required: - field - message properties: field: type: string message: type: string AssetCurrentType: type: string maxLength: 100 description: >- Compatibility slug derived from current active asset type assignments.
