A direct first-party route whose model is absent from the bundled official-docs snapshot fell through to the provider's own /models listing, which carries no prices on api.openai.com or api.x.ai, and recorded the turn as cost_status=unknown / $0 despite real billed usage (gpt-5-nano on OpenAI, grok-4.3 on xAI in the live provider canary). Widen the trusted models.dev fallback from Xiaomi to every pay-per-token first-party API (openai, xai, anthropic, google, deepseek, xiaomi), keyed by billing-route provider -> the vendor's API domain. The price applies only on HTTPS:443 to that domain (or with no base URL, i.e. the provider default), so relays, downgraded origins, custom endpoints and subscription routes (xai-oauth, openai-codex) keep their own policy. Drops the blanket try/except: get_model_info(allow_network=False) reads only the memory/disk cache and does not raise.
