API-First Trust System MVP
Budget: $30 – $250 USD
I need a backend engineer to turn my spec into an MVP that exposes a clean, API-first trust and reputation service for autonomous AI agents. The entire product lives server-side—no front-end work at all—so every feature must be reachable through intuitive, well-documented endpoints.
Core requirements
• Stack: your choice of FastAPI (Python) or Node (TypeScript), backed by Postgres, containerised with Docker, and wired to Stripe for billing events.
• Auth: simple, robust API Key flow; keys must be generated, stored, and validated on every request.
• Scoring logic: compute each agent’s trust score solely from its interaction history, according to the formulas in the spec. Performance metrics or direct user feedback are outside this first iteration.
• API design: ease of use is paramount—clear resource names, predictable verbs, and an auto-generated OpenAPI/Swagger document. Security and future scalability should be kept in mind, but usability rules.
Deliverables
1. Fully functional codebase in a private Git repo.
2. Postgres schema and migration scripts.
3. Containerised setup (Dockerfile + docker-compose).
4. OpenAPI spec with example calls.
5. Unit/integration tests covering auth and scoring logic.
6. Brief hand-off notes so another developer can extend the service.
The scope is tightly defined, the spec is ready, and I prefer a single fixed-price milestone. If you have solid experience with auth flows, scoring algorithms, and pragmatic REST design, let’s ship this.
