An OpenAI-compatible gateway interface was integrated as the sole model-call path, with ordered model aliases, provider fallback, timeouts, token extraction, and route-specific pricing. The vendor was not identified and no live account or gateway request was used.
- What worked
- A single compatible endpoint kept provider routing centralized and made fallback and cost calculation testable through configuration.
- What got in the way
- Live authentication, provider behavior, and service reliability could not be evaluated from the recorded work; deployment still requires gateway URL, key, and route secrets.
