ART TREES API Integration Specification — Data Exchange Protocol

Overview

This document outlines the technical specifications for API-based data exchange between DaedArch Corporation and ART TREES. The integration facilitates seamless data transfer for the purposes of monitoring, reporting, and verification (MRV) of carbon credits related to avoided deforestation and forest protection strategies. The integration is designed to align with the standards set forth by ART TREES, particularly in accordance with the Architecture for REDD+ Transactions, government-level crediting for avoided deforestation, and the endorsement by the LEAF Coalition.

Authentication

1.1 Authentication Method

DaedArch shall use OAuth 2.0 for authentication to ensure secure access to ART TREES API. The following steps outline the authentication process:

1. Client Registration: DaedArch must register with ART TREES to obtain a client ID and client secret.
2. Token Request: DaedArch shall send a POST request to the token endpoint to obtain an access token.

Endpoint: ` POST https://api.arttrees.org/oauth/token `

Request Body: `json { "grant_type": "client_credentials", "client_id": "YOUR_CLIENT_ID", "client_secret": "YOUR_CLIENT_SECRET" } `

1. Access Token: The response shall include an access token, which DaedArch must use in the Authorization header for subsequent API requests.

Response Example: `json { "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...", "token_type": "Bearer", "expires_in": 3600 } `

1.2 Token Expiration

The access token shall expire after the duration specified in the expires_in field. DaedArch must implement a mechanism to refresh the token using the client credentials flow when necessary.

Endpoints

2.1 Data Submission Endpoint

DaedArch shall submit environmental data to ART TREES via the following endpoint:

Endpoint: ` POST https://api.arttrees.org/data/submit `

Request Headers: `http Authorization: Bearer YOUR_ACCESS_TOKEN Content-Type: application/json `

2.2 Data Retrieval Endpoint

DaedArch shall retrieve verification-ready reports using the following endpoint:

Endpoint: ` GET https://api.arttrees.org/data/retrieve `

Request Headers: `http Authorization: Bearer YOUR_ACCESS_TOKEN `

Query Parameters:

• report_id (required): The unique identifier for the report to be retrieved.

Response Example: `json { "report_id": "string", "status": "verified", "data": { "sensor_id": "string", "timestamp": "2023-10-01T12:00:00Z", "location": { "latitude": -1.2921, "longitude": 36.8219 }, "data": { "co2_level": 400.5, "temperature": 22.3, "humidity": 60 }, "verification_chain": { "audit_trail": [ { "step": "sensor_reading", "timestamp": "2023-10-01T12:00:00Z", "details": "Reading taken from sensor." } ] } } } `

Data Models

3.1 Environmental Data Model

The environmental data submitted by DaedArch shall conform to the following data model:

| Field Name | Type | Description | Constraints | |----------------|-------------|---------------------------------------------------------------|------------------------------------| | sensor_id | string | Unique identifier for the sensor | Required, max length 50 characters | | timestamp | string | ISO 8601 formatted timestamp of the data capture | Required, format: YYYY-MM-DDTHH:mm:ssZ | | location | object | Geographic coordinates of the sensor | Required | | latitude | float | Latitude coordinate of the sensor | Required, range: -90 to 90 | | longitude | float | Longitude coordinate of the sensor | Required, range: -180 to 180 | | data | object | Environmental measurements | Required | | co2_level | float | CO2 concentration level in ppm | Required, non-negative | | temperature | float | Temperature in degrees Celsius | Required | | humidity | float | Relative humidity in percentage | Required, range: 0 to 100 | | verification_chain | object | Chain of custody and verification details | Required | | previous_report_id | string | ID of the previous report in the verification chain | Optional | | audit_trail | array | Sequence of audit steps taken during the data collection | Required | | step | string | Description of the audit step | Required | | details | string | Additional details about the audit step | Optional |

3.2 Verification Chain Model

The verification chain must include a detailed audit trail that captures the integrity of the data collected. Each step in the audit trail shall conform to the following model:

| Field Name | Type | Description | Constraints | |----------------|-------------|---------------------------------------------------------------|------------------------------------| | step | string | Description of the audit step | Required, max length 100 characters | | timestamp | string | ISO 8601 formatted timestamp of the audit step | Required, format: YYYY-MM-DDTHH:mm:ssZ | | details | string | Additional details about the audit step | Optional |

Error Handling

DaedArch shall implement robust error handling to manage API responses effectively. The following error codes and messages shall be adhered to:

| HTTP Status Code | Error Code | Description | |------------------|------------------|---------------------------------------------------------| | 400 | INVALID_REQUEST | The request format is invalid or missing required fields. | | 401 | UNAUTHORIZED | Authentication failed or access token is invalid. | | 403 | FORBIDDEN | The client does not have permission to access the resource. | | 404 | NOT_FOUND | The requested resource could not be found. | | 500 | SERVER_ERROR | An internal server error occurred. |

5.1 Error Response Structure

All error responses shall conform to the following structure:

`json { "error": { "code": "INVALID_REQUEST", "message": "The request format is invalid or missing required fields." } } `

Rate Limits

To ensure equitable access to the ART TREES API, DaedArch shall adhere to the following rate limits:

• Requests: DaedArch may make a maximum of 100 requests per minute.
• Burst Requests: A burst of up to 10 requests may be made in a single second.

6.1 Rate Limiting Response

When the rate limit is exceeded, the API shall return a 429 Too Many Requests status code along with the following response body:

`json { "error": { "code": "RATE_LIMIT_EXCEEDED", "message": "Rate limit exceeded. Please try again later." } } `

Conformity Assessment Procedures

7.1 Data Validation

ART TREES shall implement a data validation process to ensure that all incoming data from DaedArch adheres to the specified data models. The validation checks shall include:

1. Schema Validation: All incoming data must conform to the defined JSON schema.
2. Field Constraints: Each field must meet its respective constraints as outlined in the data models.
3. Timestamp Validation: All timestamps must be in valid ISO 8601 format.

7.2 Audit Trail Verification

ART TREES shall conduct periodic audits of the verification chains submitted by DaedArch to ensure the integrity and accuracy of the data. The audit process will include:

1. Random Sampling: A random sample of submitted data will be selected for detailed examination.
2. Cross-Verification: Data will be cross-verified with independent sources where applicable.

7.3 Reporting and Feedback

ART TREES shall provide DaedArch with periodic reports on the status of data submissions, including:

• Number of successful submissions
• Number of errors encountered
• Feedback on data quality and areas for improvement

Conclusion
