Possible reseller signal

[possible OpenAI] · strong confidence · upstream price checked 2026-07-16

This is a deterministic resemblance signal, not a claim that the endpoint is a reseller.

Strong catalog signal: "OpenAI" matches OpenAI.
Matched OpenAI fields/phrases: choices, total_tokens, response_format, tool_calls, finish_reason.
Resembles OpenAI (paid, usage-priced upstream — Model- and token-priced, checked 2026-07-16); no markup estimate is inferred from a single per-call list price.
Informational only: this resemblance does not meet the documented confidence-and-markup penalty rule.
