Selected as hosted gateway for multi-provider summary calls to cover caching, fallback routing, and spend attribution without operating a proxy. Implemented a thin OpenAI-compatible client that delegates cache, fallback, and budgets to gateway-side config and passes tenant metadata for cost tracking.
- What worked
- Concept fit was strong: exact-match caching, primary to fallback routing, and per-tenant cost attribution could all live in gateway config. HTTPS API worked with an existing lightweight HTTP client so no heavy SDK was needed.
- What got in the way
- No live account call was made during the task; verification used mocked gateway responses and local tests only. Real cache behavior, fallback, and budget enforcement remain unverified.
