# PublicEndpoint

Information about a specific model endpoint

## Fields

| Field | Type | Required | Description | Example |
| - | - | - | - | - |
| `ContextLength` | `int64` | :heavy\_check\_mark: | N/A | |
| `LatencyLast30m` | [\*components.PercentileStats](../../models/components/percentilestats.mdx) | :heavy\_check\_mark: | Latency percentiles in milliseconds over the last 30 minutes. Latency measures time to first token. Only visible when authenticated with an API key or cookie; returns null for unauthenticated requests. | \{<br />"p50": 25.5,<br />"p75": 35.2,<br />"p90": 48.7,<br />"p99": 85.3<br />} |
| `MaxCompletionTokens` | `*int64` | :heavy\_check\_mark: | Maximum completion tokens for this endpoint. Input and output tokens share the context window, so the effective maximum output for a request is further limited by the context remaining after input tokens. | |
| `MaxPromptTokens` | `*int64` | :heavy\_check\_mark: | N/A | |
| `ModelID` | `string` | :heavy\_check\_mark: | The unique identifier for the model (permaslug) | openai/gpt-4 |
| `ModelName` | `string` | :heavy\_check\_mark: | N/A | |
| `Name` | `string` | :heavy\_check\_mark: | N/A | |
| `NativeTools` | map\[string][components.NativeTools](../../models/components/nativetools.mdx) | :heavy\_check\_mark: | The server tools this endpoint accepts as the provider's own built-in tool (`engine: "native"`) instead of an OpenRouter engine, keyed by canonical `openrouter:*` name. Each value names the provider tool type the request is translated to. Where that tool runs (provider-side, or returned to the client as with Anthropic bash) is documented per tool. Empty when the provider has none. | \{<br />"openrouter:web\_search": \{<br />"type": "web\_search\_20260209"<br />}<br />} |
| `PerfLast30mByWorkload` | [\*components.PerfLast30mByWorkload](../../models/components/perflast30mbyworkload.mdx) | :heavy\_minus\_sign: | Endpoint performance over the last 30 minutes, keyed by the kind of request served (e.g. `text_generation`, `image_generation`). Additive to the legacy singular latency and throughput fields; image and video generation report end-to-end latency. Only visible when authenticated with an API key or cookie. | |
| `Pricing` | [components.Pricing](../../models/components/pricing.mdx) | :heavy\_check\_mark: | N/A | |
| `ProviderName` | [components.ProviderName](../../models/components/providername.mdx) | :heavy\_check\_mark: | N/A | OpenAI |
| `Quantization` | [\*components.Quantization](../../models/components/quantization.mdx) | :heavy\_check\_mark: | N/A | fp16 |
| `Status` | [\*components.EndpointStatus](../../models/components/endpointstatus.mdx) | :heavy\_minus\_sign: | N/A | 0 |
| `SupportedParameters` | \[][components.Parameter](../../models/components/parameter.mdx) | :heavy\_check\_mark: | N/A | |
| `SupportsImageReference` | `*bool` | :heavy\_minus\_sign: | Whether this TTS endpoint accepts an `image_url` reference describing the desired voice. Requests carrying an image reference are only routed to endpoints where this is true. | |
| `SupportsImplicitCaching` | `bool` | :heavy\_check\_mark: | N/A | |
| `SupportsMultipleAudioReferences` | `*bool` | :heavy\_minus\_sign: | Whether this TTS endpoint accepts more than one `input_audio` reference clip per request. Requests carrying several clips are only routed to endpoints where this is true. | |
| `SupportsToolChoice` | [components.ToolChoiceSupport](../../models/components/toolchoicesupport.mdx) | :heavy\_check\_mark: | Per-variant `tool_choice` support. `tool_choice` in `supported_parameters` only says the parameter is accepted; these flags say which of its values passed testing. | \{<br />"auto": true,<br />"function": true,<br />"none": true,<br />"required": true<br />} |
| `SupportsVoiceCloning` | `*bool` | :heavy\_minus\_sign: | Whether this TTS endpoint accepts inline reference audio (`input_references`) for stateless voice cloning. Requests carrying reference audio are only routed to endpoints where this is true. | |
| `Tag` | `string` | :heavy\_check\_mark: | N/A | |
| `ThroughputLast30m` | [\*components.PercentileStats](../../models/components/percentilestats.mdx) | :heavy\_check\_mark: | N/A | \{<br />"p50": 25.5,<br />"p75": 35.2,<br />"p90": 48.7,<br />"p99": 85.3<br />} |
| `UptimeLast1d` | `*float64` | :heavy\_check\_mark: | Uptime percentage over the last 1 day, calculated as successful requests / (successful + error requests) \* 100. Rate-limited requests are excluded. Returns null if insufficient data. | |
| `UptimeLast30m` | `*float64` | :heavy\_check\_mark: | N/A | |
| `UptimeLast5m` | `*float64` | :heavy\_check\_mark: | Uptime percentage over the last 5 minutes, calculated as successful requests / (successful + error requests) \* 100. Rate-limited requests are excluded. Returns null if insufficient data. | |
