Gold Standard API Integration Specification — Data Exchange Protocol

Overview

This document outlines the technical specifications for the API-based data exchange between DaedArch Corporation and Gold Standard. The purpose of this integration is to facilitate the seamless transfer of environmental data captured by DaedArch’s sensor-based Measurement, Reporting, and Verification (MRV) platform to Gold Standard’s systems, ensuring compliance with the standards set forth by Gold Standard, particularly regarding carbon credits and sustainable development goals (SDGs).

Scope

This specification applies to all data exchange operations between DaedArch and Gold Standard, including but not limited to the submission of carbon credit data, SDG co-benefits, and stakeholder consultation records. All data exchanged must comply with the Gold Standard’s requirements for projects in developing nations and must demonstrate the associated SDG co-benefits beyond carbon reduction.

Authentication

Authentication Mechanism

DaedArch shall use OAuth 2.0 for authentication when accessing Gold Standard’s API. All requests must include a valid access token in the Authorization header.

Access Token Request

` POST /oauth/token `

Request Body

`json { "grant_type": "client_credentials", "client_id": "", "client_secret": "" } `

Response

Upon successful authentication, the response shall include the following fields:

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

Token Expiry

Access tokens shall expire after 3600 seconds. DaedArch must implement a mechanism to refresh tokens as necessary to maintain uninterrupted service.

Endpoints

Rate Limits

Rate Limiting Policy

To ensure fair use of the API, Gold Standard shall enforce rate limits on API requests as follows:

• Requests per minute: 100 requests
• Requests per hour: 1000 requests

Exceeding Rate Limits

If DaedArch exceeds the defined rate limits, the API shall respond with a 429 Too Many Requests status code and the following error message:

`json { "status": "error", "code": "429", "message": "Rate limit exceeded. Please try again later." } `

Verification Chains

Data Integrity and Verification

To maintain data integrity, DaedArch shall implement a verification chain that includes:

1. Data Collection: Captured via IoT sensors with timestamp and geolocation.
2. Data Processing: Processed through certified algorithms ensuring accuracy.
3. Data Submission: Submitted to Gold Standard API with a unique submission ID.
4. Data Confirmation: Confirmation of successful submission received from Gold Standard.
5. Audit Trail: All transactions logged with timestamps for audit purposes.

Audit Procedures

1. Internal Audits: DaedArch shall perform quarterly internal audits to ensure compliance with data submission protocols and accuracy of reported data.
2. External Audits: Gold Standard may conduct annual external audits to verify compliance with the standards and requirements.
3. Documentation: All audit findings shall be documented and made available upon request to Gold Standard.

Conclusion

This API Integration Specification serves as a comprehensive guide for DaedArch Corporation to ensure compliance with Gold Standard’s requirements for carbon credit data exchange. Adherence to the outlined protocols, data formats, and verification processes is mandatory to maintain the integrity of the carbon market and support sustainable development goals.
