Models and supply tiers
ModelMart accepts one request format and routes it to an eligible listing. Select a model with the model field:
{ "model": "claude-sonnet-5", "messages": [{"role": "user", "content": "Hello"}] }
Three listing tiers
- First-party: ModelMart owns the credential. The prompt goes only to the original provider.
- Verified: a seller uses their credential with a provider domain on the whitelist. The seller does not see the prompt; the original provider still receives the request.
- Community: a seller operates a private endpoint. The seller may see prompts and responses. This tier always requires a warning and
allow_communityopt-in.

Unknown models
If a model does not exist or its listing is unavailable, the gateway returns 404 model_not_found. Check the spelling and the key's Community permission.
