Parameters:

• grant_type: This shall always be client_credentials.
• client_id: The unique identifier for DaedArch assigned by ICROA.
• client_secret: The secret key provided to DaedArch by ICROA.

1.2 Token Response

Upon successful authentication, the response will include the access token:

`json { "access_token": "eyJz93a...k4laUW", "token_type": "Bearer", "expires_in": 3600 } `

Fields:

• access_token: The token to be used for subsequent API requests.

• sensor_data: An array of sensor data objects.
• verification_report: An object containing the verification report details.

3. Additional Endpoints

Additional endpoints may be defined as necessary to accommodate the evolving needs of the ICROA standards and the DaedArch platform. These shall include but are not limited to endpoints for querying verification statuses, updating project details, and retrieving accreditation statuses.

Data Models

1. Carbon Offset Data Model

The carbon offset data model shall adhere to the following structure:

`json { "project_id": "string", "sensor_data": [ { "sensor_id": "string", "timestamp": "ISO8601", "value": "number" } ], "verification_report": { "report_id": "string", "report_url": "string" } } `

2. Verification Report Model

The verification report model shall be defined as follows:

`json { "report_id": "string", "report_url": "string", "created_at": "ISO8601", "updated_at": "ISO8601", "status": "string" } `

Fields:

• report_id: Unique identifier for the verification report (string).
• report_url: URL to access the verification report (string).
• created_at: Timestamp of report creation (ISO 8601).
• updated_at: Timestamp of last report update (ISO 8601).
• status: Current status of the verification report (string).

Error Handling

1. Error Response Structure

In the event of an error, the API shall return a standardized error response format:

`json { "status": "error", "error_code": "string", "message": "string" } `

Fields:

• status: The status of the response (string).
• error_code: A unique error code representing the type of error (string).
