# api_ollama specification
- **Name:** api_ollama
- **Version:** 0.6
- **Date:** 2025-09-28
- **Status:** Production Ready
- **System Specification:** [../../spec.md](../../spec.md)
## document overview
This specification defines a Rust library crate (`api_ollama`) that provides HTTP client functionality for Ollama's local LLM runtime API. The specification is structured in three parts: **Part I** defines the mandatory public contract (what the library must provide), **Part II** provides recommended internal design approaches (how it could be implemented), and **Part III** establishes project governance and development principles.
**Architecture Decision**: This API crate is designed as a **stateless HTTP client** with no persistence requirements. All operations are direct HTTP calls to the Ollama API without local data storage, caching, or state management beyond request/response handling.
**Governing Principle**: "Thin Client, Rich API" - Expose all server-side functionality transparently while maintaining zero client-side intelligence or **automatic** behaviors. Enterprise reliability features (retry logic, circuit breakers, rate limiting) are explicitly **allowed and encouraged** when implemented with explicit developer configuration and transparent operation.
**Note:** This specification must be implemented in accordance with the ecosystem-wide requirements defined in the [System Specification](../../spec.md).
## specification type: reusable rust library
This specification follows the **Directory Structure** for multi-file specifications, organizing content across focused documents for improved comprehension and maintenance.
## organization
The specification is organized into three main parts:
### [part I: public contract (mandatory requirements)](1_public_contract.md)
Defines what the library must provide - the mandatory external interface and behavior:
1. Goal
2. Problem Solved
3. Vision & Scope
4. Ubiquitous Language
5. Success Metrics
6. System Actors
7. Functional Requirements
8. Non-Functional Requirements
9. Limitations
10. External System Dependencies & Interfaces
### [part II: internal design (design recommendations)](2_internal_design.md)
Provides recommended approaches for implementation - how it could be built:
11. System Architecture
12. Rust Library Design: Granular Feature Gating
13. Infrastructure Support
14. Data Stores
15. Architectural & Flow Diagrams
16. Internal Data Models
17. Reference Implementation
### [part III: project & process governance](3_governance.md)
Establishes development principles and project management practices:
18. Open Questions
19. Core Principles of Development
20. Deliverables
## quick navigation
- **For API Users**: Start with [Part I: Public Contract](1_public_contract.md)
