API Modes

Mode	Features	Best For
Read-Only	GET only, deterministic, infinite pagination	Frontend dev, demos, testing
Stateful CRUD	Full CRUD, configurable TTL (1h/24h/7d/never)	E2E testing, mobile dev

---

Deterministic Pagination

Same request always returns the same data. Page 999 works—generated on-demand, not stored.

Request: GET /users?page=5&per_page=10

Algorithm:
1. page_seed = hash(project_seed + endpoint + page_number)
2. For each item i in page:
   item_seed = hash(page_seed + i)
   generate(item_seed) → deterministic user

Result:
• Same request always returns same data
• Relationships maintained via FK seeds
• No storage cost (generated on-the-fly)

Filtering:

GET /users?age_gt=30
→ Generate candidates, filter, return page_size matches
→ Consistent via deterministic generation
