request-translation-sanitization

API request translation between Anthropic and OpenAI compatible endpoints adapts parameter shapes and maps unsupported fields to supported formats. This sanitization process ensures compatibility when moving requests across third-party APIs while preserving safety rules.

API request sanitization is the process of aligning request parameters before sending them to Codex or OpenAI endpoints. It handles default values and thinking-related fields, omitting unsupported parameters to enforce strict endpoint compatibility.

Default values are omitted during API request translation to prevent accidental surface area expansion. Unless explicitly gated, removing these values ensures the translated request contains only necessary parameters, maintaining endpoint compatibility.

Request sanitization preserves safety rules when translating to Codex endpoints. It reuses existing translator logic to maintain policy constraints while adapting parameter shapes and handling endpoint-specific unsupported parameters.

Handling unsupported parameters in Anthropic API requests involves mapping them to supported names and formats or omitting them entirely. The sanitization process enforces omission for unsupported fields to ensure third-party endpoint compatibility.
