> ## 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 If a page is wrong or out of date, report it with the MCP `submit_feedback` tool.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.

# Generation lookup

> Call /generations to retrieve a past generation.

**Method**: `getGeneration()`

### Example

```php theme={null}
<?php

require 'vendor/autoload.php';

use Phaseo\Sdk\Phaseo;

$apiKey = getenv('PHASEO_API_KEY');
$client = new Phaseo(apiKey: $apiKey);

$record = $client->getGeneration('G-01ABC...');
```

### Parameters

* `id` (string, required): Request id returned by a previous call.

### Returns

GatewayGenerationRecord

When request details were stored, the returned record also includes `replay_supported` and `replay_request` so you can resubmit the captured payload to the original endpoint.

Timing fields follow the shared gateway semantics:

* `latency_ms`: time to first token or first output byte/frame when tracked
* `generation_ms`: post-latency generation time when tracked
