Get Request Inputs

Overview#

When you use Prompt Management through the AI Gateway, template variables (inputs) are stored automatically. This endpoint lets you retrieve those inputs by request ID — useful for building testing pipelines that replay past requests against new prompt versions.

Use Cases#

• Regression testing: Pull a past request's inputs and replay them against a new prompt version to validate behavior.
• Prompt comparison: Compare outputs across prompt versions using the same inputs, without storing inputs separately on your end.
• Debugging: Inspect the exact variables that were injected into a prompt template at runtime.

Response#

Returns null for data if the request has no associated inputs (e.g., the request was not made through prompt management, or the request ID doesn't exist).
