# Fetch a provider

GET

/v1/providers/{providerId}

```sh
curl --request GET \
  --url https://example.com/v1/providers/example \
  --header 'Authorization: Bearer <token>'
```

Returns the wire-safe `ProviderMetadata` (routing metadata only — secrets never cross the wire).

## Authorizations

- **[bearerAuth](https://docs.kindgi.com/v0.3.1/reference/api.md#bearerauth)**

## Parameters

### Path Parameters

**providerId**

required

string

ProviderId — opaque string identifier chosen by the deployment.

## Responses

### 200

Provider metadata.

application/json

object

**id**

required

string

\>= 1 characters

**region**

required

Region the connection routes to. All models on this provider share the region (the same models served from two clouds or regions are separate providers). `'unspecified'` when not region-scoped.

string

\>= 1 characters /^\[a-z]\[a-z0-9-]{0,62}$/

**models**

required

Models this connection exposes. Non-empty. `models[i].name` must be unique within the list.

Array\<object>

\>= 1 items

object

**name**

required

Vendor-facing model id passed to the SDK (e.g. `claude-sonnet-5-5`).

string

\>= 1 characters

**contextWindow**

required

Context window in tokens.

integer

\>= 1

**features**

required

Features this model supports (tool-use, thinking, structured-output, …).

Array\<string>

Allowed values: structured-output vision audio-input audio-output tool-use parallel-tool-use thinking long-context code-execution web-search file-search streaming batch

**cost**

required

USD per 1K tokens. An adapter may take more rate fields (see the adapter’s README).

object

**promptUsdPer1kTokens**

required

number

**completionUsdPer1kTokens**

required

number

**_key_**

additional properties

any

**p95LatencyMs**

Best-effort p95 latency estimate in milliseconds. Varies by model.

number

**maxOutputTokens**

Fallback cap on output tokens. Adapters that require `max_tokens` on every request (e.g. Anthropic) use this when `ModelCallInput.maxOutputTokens` is unset.

integer

\>= 1

**sampling**

Whether the model takes sampling settings (`temperature`). `false`: its API rejects a non-default value, so the call goes without one and the answer’s `warnings` say so (`sampling-unsupported`). Absent: it takes them.

boolean

**thinking**

How the model thinks before it answers, and the levels it takes, so a call’s level (an agent’s model settings, or a judge’s `lowest`) is sent as one it takes: any other is rounded to the next one it takes, or its highest, with a `thinking-level-adjusted` warning. Absent: it doesn’t think, or nothing is known, and nothing is sent for it.

object

**mode**

required

`adaptive`: on unless turned down. `always`: on, and it can only be lowered.

string

Allowed values: adaptive always

**lowest**

required

The vendor’s own setting for the least thinking: for Anthropic `disabled`, `between_tools` or an effort (`low`); for Gemini a thinking level (`low`, `minimal`); for OpenAI a reasoning effort (`low`, `none`).

string

\>= 1 characters

**levels**

The levels the model takes besides `lowest`, least first. Absent: `low`, `medium` and `high`, which every thinking model takes, plus `minimal` when `lowest` is `minimal`, minus those below `lowest` when it is `low`, `medium` or `high` (any case).

Array\<string>

unique items

Allowed values: minimal low medium high xhigh max

**default**

The level a call that asks none is sent. It must be `lowest` or one the model takes (`levels`), or the registration is refused. Absent: the vendor’s default.

string

Allowed values: lowest minimal low medium high xhigh max

**description**

Short per-model description surfaced in logs.

string

**defaultModel**

The model to use when an agent doesn’t choose: one of `models[].name`. When candidates rank equally, it comes before the provider’s other models; without it, ties break by model name. A preset sets it. A runtime before 0.1.4 ignores it.

string

\>= 1 characters

**attributes**

Soft attributes for preference-ranking (`local`, `lower-cost`, `higher-accuracy`, …). Matched by string equality against `Preference.feature`.

Array\<string>

**description**

Short human description of the connection.

string

**capabilityKind**

Kind of resource this provider fulfils. Absent = `llm-inference`. Adapters for other kinds (embedding, gpu-compute, sandbox-exec, …) set this explicitly.

string

**fallback**

A fallback serves a capability only when no other provider satisfies it (e.g. `kindgi dev`’s scripted `dev-echo`); an agent turn routed to one carries a `fallback-provider` warning. Absent = `false`.

boolean

**labels**

Bookkeeping, such as who manages the provider; the router ignores labels. At most 32 keys; a key is 1-63 lowercase letters and digits, with `.`, `-`, `_` or `/` inside; a value is at most 256 characters. The convention key `kindgi.com/managed-by` names the manager (`kindgi-dev`, `kindgi-deploy:<environment>`). Out of bounds: `400 invalid-provider`, reason `invalid-labels`.
