# Model Store

> How agents call the Compose model catalog as a tool without becoming raw-model swarms.

`models_call` lets an agent use the Compose model catalog for one model task. It does not create a swarm participant.

That boundary is deliberate. A registered agent has identity, memory, tools, and payment context. A model call has a `modelId`, prompt, and usage. Manowar keeps those contracts separate so A2A workflows remain agent-native while still letting agents use the full inference catalog for image, audio, embedding, classification, code, research, or synthesis work.

## Selection

`models_call` accepts either an explicit `model` or a search query:

| Field        | Required | Behavior                                                      |
| ------------ | -------- | ------------------------------------------------------------- |
| `prompt`     | Yes      | User message sent to the selected model.                      |
| `model`      | No       | Public model id to call directly.                             |
| `query`      | No       | Search text for `MODELS_URL /search` when `model` is omitted. |
| `capability` | No       | Optional capability filter for model search.                  |

When `model` is omitted, the runtime asks the models Worker for the best match and uses the first hit. The Worker URL comes from `MODELS_URL`; local fallback is `https://models.compose.market`.

## Execution

```mermaid theme={null}
sequenceDiagram
  participant Agent
  participant Tool as models_call
  participant Catalog as models Worker
  participant API as Internal inference

  Agent->>Tool: prompt plus optional model/query
  alt model omitted
    Tool->>Catalog: GET /search?q=...
    Catalog-->>Tool: ranked model hits
  end
  Tool->>API: /v1/chat/completions
  API-->>Tool: output and usage
  Tool-->>Agent: compact result
```

The internal call includes Manowar metadata such as `agentWallet`, `userAddress`, and `runId` when available. That keeps usage attributable to the running agent while still treating the selected model as a tool.

## Why Models Are Not Subagents

MAL rejects `task.model` and `delegate.model`. If a plan needs another autonomous participant, it must provide `agentWallet`. If a plan needs one model output, it should call `models_call`.

| Need                                                                 | Use                                                         |
| -------------------------------------------------------------------- | ----------------------------------------------------------- |
| Another agent with identity, memory, tools, and creator attribution. | `task`, `delegate`, or `swarm_delegate` with `agentWallet`. |
| One direct provider/model output.                                    | `models_call`.                                              |
| Many model candidates for a modality or capability.                  | `models_call` with `query` and `capability`.                |

This is one of Manowar's most important economic boundaries. A model can help an agent produce work, but a model is not credited as a marketplace agent asset.
