API Design
|
|
=========
|
|
|
|
This document outlines the API design principles and specifications for the AI-Writer platform.
|
|
|
|
API Design Principles
|
|
-------------------
|
|
|
|
The AI-Writer API follows these core design principles:
|
|
|
|
1. **RESTful Architecture**
|
|
|
|
* Resource-oriented design
|
|
* Standard HTTP methods (GET, POST, PUT, DELETE)
|
|
* Consistent URL structure
|
|
* Stateless interactions
|
|
|
|
2. **Consistent Response Format**
|
|
|
|
* JSON as the primary data format
|
|
* Standard error response structure
|
|
* Pagination for list endpoints
|
|
* Hypermedia links where appropriate
|
|
|
|
3. **Versioning**
|
|
|
|
* API versioning in URL path (e.g., `/api/v1/`)
|
|
* Backward compatibility within major versions
|
|
* Deprecation notices before removing features
|
|
|
|
4. **Security**
|
|
|
|
* Authentication via API keys or OAuth 2.0
|
|
* Rate limiting to prevent abuse
|
|
* Input validation to prevent injection attacks
|
|
* HTTPS for all communications
|
|
|
|
5. **Documentation**
|
|
|
|
* OpenAPI/Swagger specification
|
|
* Interactive documentation
|
|
* Code examples for common operations
|
|
* Changelog for API updates
|

|
|
|
|
API Authentication
|
|
----------------
|
|
|
|
The AI-Writer API supports the following authentication methods:
|
|
|
|
1. **API Key Authentication**
|
|
|
|
* Include the API key in the Authorization header:
|
|
`Authorization: Bearer {api_key}`
|
|
* API keys can be generated and managed through the API or web interface
|
|
* Different permission levels can be assigned to API keys
|
|
|
|
2. **OAuth 2.0 (for multi-user deployments)**
|
|
|
|
* Standard OAuth 2.0 flow with authorization code
|
|
* Supports scopes for fine-grained permissions
|
|
* Refresh token rotation for enhanced security
|
|
|
|
Rate Limiting
|
|
-----------
|
|
|
|
To ensure fair usage and system stability, the API implements rate limiting:
|
|
|
|
* Rate limits are based on the user's plan
|
|
* Limits are applied per API key
|
|
* Rate limit information is included in response headers:
|
|
* `X-RateLimit-Limit`: Total requests allowed in the current period
|
|
* `X-RateLimit-Remaining`: Requests remaining in the current period
|
|
* `X-RateLimit-Reset`: Time when the rate limit resets (Unix timestamp)
|
|
|
|
When a rate limit is exceeded, the API returns a 429 Too Many Requests response.
|
|
|
|
Pagination
|
|
---------
|
|
|
|
List endpoints support pagination with the following parameters:
|
|
|
|
* `limit`: Number of items per page (default: 20, max: 100)
|
|
* `offset`: Number of items to skip (for offset-based pagination)
|
|
* `cursor`: Cursor for the next page (for cursor-based pagination)
|
|
|
|
Response includes pagination metadata:
|
|
|
|
.. code-block:: json
|
|
|
|
{
|
|
"data": [...],
|
|
"pagination": {
|
|
"total": 45,
|
|
"limit": 20,
|
|
"offset": 0,
|
|
"next_cursor": "cursor_for_next_page",
|
|
"has_more": true
|
|
}
|
|
}
|
|
|
|
Filtering and Sorting
|
|
-------------------
|
|
|
|
List endpoints support filtering and sorting:
|
|
|
|
* Filtering: `?field=value&another_field=another_value`
|
|
* Range filtering: `?created_at_gte=2023-01-01&created_at_lte=2023-01-31`
|
|
* Sorting: `?sort=field` (ascending) or `?sort=-field` (descending)
|
|
* Multiple sort fields: `?sort=-created_at,title`
|
|
|
|
Versioning Strategy
|
|
-----------------
|
|
|
|
The API uses a versioning strategy to ensure backward compatibility:
|
|
|
|
1. **Major Versions**
|
|
|
|
* Included in the URL path: `/api/v1/`, `/api/v2/`, etc.
|
|
* Major versions may introduce breaking changes
|
|
* Previous major versions are supported for at least 12 months after a new version is released
|
|
|
|
2. **Minor Updates**
|
|
|
|
* Backward-compatible changes within a major version
|
|
* New endpoints or parameters may be added
|
|
* Existing functionality remains unchanged
|
|
|
|
3. **Deprecation Process**
|
|
|
|
* Features to be removed are marked as deprecated
|
|
* Deprecation notices are included in response headers
|
|
* Deprecated features are supported for at least 6 months before removal
|
|
|
|
