Model discovery

MethodPathPurpose
GET/v1/modelsList models visible to the current credentials
GET/v1/models/{model}Retrieve one model’s available metadata

Use https://api.fenno.ai as the host and Authorization: Bearer <FENNO_API_KEY>. The OpenAI SDK uses a base URL ending in /v1.

List models

import os
from openai import OpenAI
 
client = OpenAI(
    base_url="https://api.fenno.ai/v1",
    api_key=os.environ["FENNO_API_KEY"],
    timeout=60.0,
    max_retries=0,
)
 
for model in client.models.list():
    print(model.id)

The HTTP response follows the OpenAI list shape with object: "list" and data[] model objects. Use each id exactly as returned; do not add another provider’s namespace or copy a display label.

Retrieve a model

model = client.models.retrieve(os.environ["FENNO_MODEL"])
print(model.id)

A model object may include fields such as object, created and owned_by. These are metadata, not a guarantee that every protocol or feature is available.

Discovery is not a capability test

  • A listed ID does not by itself establish context length, price, tool support, image input or Responses compatibility.
  • Access and model availability can change; handle unavailable models at request time.
  • Verify the intended endpoint with a small request and consult the account’s model information.
  • Preserve a known configuration rather than randomly selecting the first listed model in production.

See model selection and capabilities and the integration checklist.
