> ## Agent Instructions
> Phaseo Gateway base URL: https://api.phaseo.app/v1. Send `Authorization: Bearer $PHASEO_API_KEY` with every request.
> Model IDs look like `provider/model`, for example `openai/gpt-6-astra`. Do not guess IDs: list them with `GET /v1/models` or check https://phaseo.app/models. `phaseo/free` routes to an available free model and needs no wallet balance.
> For new text integrations prefer `POST /v1/responses`. `POST /v1/chat/completions` (OpenAI format) and `POST /v1/messages` (Anthropic format) suit existing code.
> The full API contract is https://phaseo.app/docs/openapi/v1/openapi.yaml. Official SDKs: `@phaseo/sdk` (TypeScript) and `phaseo` (Python), plus Go, C#, PHP, Ruby and Rust.
> Search these docs over MCP at https://phaseo.app/docs/mcp, and install Phaseo skills with `npx skills add https://phaseo.app/docs`. If a page is wrong or out of date, report it with the MCP `submit_feedback` tool.
> Manage Phaseo accounts with the `phaseo` CLI (`npm install -g @phaseo/cli`, then `phaseo login` or `phaseo login --device-code`), the `/v1` Management API or the MCP server at `https://mcp.phaseo.app/mcp?access=manage`. Do not send users to the dashboard for account tasks. A person is still needed for sign-up, approving a sign-in, paying the first top-up on the checkout link that `phaseo credits add` returns when no card is saved, confirming each saved-card top-up from the emailed link, and account security (password, MFA, passkeys). Create API keys with `phaseo keys create --name <name> --json`; never guess one. Credit top-ups need `phaseo login --scopes billing:write` first. Task map: https://phaseo.app/docs/v1/developers/manage-from-an-agent.md.

# Files

> Call /files with the TypeScript SDK.

**Methods**: `client.uploadFile()`, `client.listFiles()`, `client.getFile()`, `client.getFileContent()`.

### Example

```typescript theme={null}
const uploaded = await client.uploadFile({ purpose: "batch", file: new Blob(["{}"]) });
const file = await client.getFile(uploaded.id);
const content = await client.getFileContent(uploaded.id);
```

> [!NOTE]
>
> `client.listFiles()` exists, but `GET /files` currently returns `file_list_not_supported_with_shared_gateway_key`
> when you use the shared gateway key. Persist the `uploaded.id` value and retrieve files directly.

### Key parameters

* `file` (required for upload): Blob/File/base64/string.
* `purpose` (required for upload): e.g., `batch`.

### Returns

`FileObject` (upload/get)

```json theme={null}
{
  "id": "file-123",
  "object": "file",
  "filename": "data.json",
  "purpose": "batch",
  "status": "processed",
  "created_at": 1677610602,
  "bytes": 123
}
```

Or `FileListResponse` (list when the underlying provider key supports file enumeration)

```json theme={null}
{
  "data": [
    {
      "id": "file-123",
      "object": "file",
      "filename": "data.json",
      "purpose": "batch",
      "status": "processed",
      "created_at": 1677610602,
      "bytes": 123
    }
  ]
}
```
