Receipts

Every response tells you who served it and whether they passed.

"receipt": { "model": "deepseek-v4-1-flash", "provider": "DeepInfra", "identity": "match", "reference": false, "checked": "2026-11-11", "mode": "strict", "allowed": 10, "added_ms": 2 }

Fields

  • provider who served this request, as reported by OpenRouter
  • identity match, watching or no match
  • reference true when the maker itself served it
  • checked date of the last check run
  • allowed how many providers this request was allowed to use
  • added_ms time our proxy added

Streaming

Streamed responses carry the same facts as headers. The serving provider is in each chunk's provider field.
