- Standard input and output token rates for the public Discount Offers group, observed 2026-10-08. Check your account group and current rates in the console before calling a model.
- Can I use Claude Code or Codex?
- Claude Code uses the Anthropic Messages endpoint. Codex uses Responses. Select a model with the required endpoint and check the key permissions.
- Does a listed endpoint prove every feature works?
- No. The catalog records configured endpoints. Parameters, limits and client compatibility depend on the model and channel. Test your required workflow before migrating traffic.
