3	## REST API Principles
4
5	### Resource Naming
6
7	- Nouns, not verbs: `/users` not `/getUsers`
8	- Plural forms: `/users`, `/orders`
9	- Hierarchical: `/users/{id}/orders`
10	- Consistent naming conventions
11
12	### HTTP Methods
13
14	\| Method \| Purpose \| Idempotent \|
15	\| ------ \| -------- \| ---------- \|
16	\| GET \| Retrieve \| Yes \|
17	\| POST \| Create \| No \|
18	\| PUT \| Replace \| Yes \|
19	\| PATCH \| Update \| No \|
20	\| DELETE \| Remove \| Yes \|
21
22	### Status Codes
23
24	- 200 OK - Success
25	- 201 Created - Resource created
26	- 204 No Content - Success, no body
27	- 400 Bad Request - Client error
28	- 401 Unauthorized - Auth required
29	- 403 Forbidden - No permission
30	- 404 Not Found - Resource missing
31	- 409 Conflict - State conflict
32	- 422 Unprocessable - Validation failed
33	- 500 Internal Error - Server error
34
35	### Response Format
36
37	```json
38	{
39	"data": { ... },
40	"meta": {
41	"page": 1,
42	"perPage": 20,
43	"total": 100
44	},
45	"links": {
46	"self": "/users?page=1",
47	"next": "/users?page=2"
48	}
49	}
50	```
51
52	### Error Format
53
54	```json
55	{
56	"error": {
57	"code": "VALIDATION_ERROR",
58	"message": "Validation failed",
59	"details": [
60	{
61	"field": "email",
62	"message": "Invalid email format"
63	}
64	]
65	}
66	}
67	```
68
69	## GraphQL Principles
70
71	### Schema Design
72
73	- Clear type definitions
74	- Nullable by default, explicit non-null
75	- Input types for mutations
76	- Connection pattern for pagination
77
78	### Query Design
79
80	- Avoid over-fetching
81	- Use fragments for reuse
82	- Implement DataLoader for N+1
83
84	## OpenAPI Specification
85
86	Generate complete OpenAPI 3.0 specs with:
87
88	- Path definitions
89	- Request/response schemas
90	- Authentication schemes
91	- Example values
92	- Error responses
93
94	## API Documentation
95
96	- Getting started guide
97	- Authentication flow
98	- Rate limiting details
99	- Versioning strategy
100	- Code examples (curl, JS, Python)
101	- Changelog
102
103	## Security Considerations
104
105	- Authentication (JWT, OAuth, API keys)
106	- Rate limiting
107	- Input validation
108	- Output filtering
109	- CORS configuration
