API reference

Models

List the models your key can call and retrieve details for one. The endpoint mirrors OpenAI’s /models, so existing model-listing code works. Use a model’s id as the model parameter in a chat request.

List models #

GET https://api.merius.ai/models — return every model available to your key.

List models

curl https://api.merius.ai/v1/models \
  -H "Authorization: Bearer $MERIUS_API_KEY"

The model object #

Each entry describes one model. The fields match OpenAI’s model object so your existing parsing works:

Example entry

{
  "id": "qwen/qwen3-30b-a3b",
  "object": "model",
  "created": 1768000000,
  "owned_by": "z-ai"
}

Field	Type	Description
`id`	string	The model slug — use this as the model parameter, e.g. qwen/qwen3-30b-a3b.
`object`	string	Always model.
`created`	integer	Unix timestamp of when the model was made available.
`owned_by`	string	The organization that owns the model weights, e.g. z-ai or deepseek.

Retrieve a model #

GET https://api.merius.ai/models/{id} — return one model by its id.

Context lengths, quantization, and per-token prices for every model are on the pricing section of the home page. New open models are added as they ship.
