## Fields

| Field | Type | Required | Description | Example |
| - | - | - | - | - |
| `allowedApiKeyHashes` | *string*\[] | :heavy\_minus\_sign: | Optional allowlist of OpenRouter API key hashes (`api_keys.hash`) that may use this credential. `null` means no restriction. Must contain at least one hash if provided. Hashes that do not belong to your account return a 400. | \[<br />"f01d52606dc8f0a8303a7b5cc3fa07109c2e346cec7c0a16b40de462992ce943"<br />] |
| `allowedModels` | *string*\[] | :heavy\_minus\_sign: | Optional allowlist of model slugs this credential may be used for. `null` means no restriction. | null |
| `allowedUserIds` | *string*\[] | :heavy\_minus\_sign: | Optional allowlist of user IDs that may use this credential. `null` means no restriction. | null |
| `declaredZdr` | *boolean* | :heavy\_minus\_sign: | Your declaration of whether the upstream provider account behind this credential has zero data retention (ZDR). `null` inherits OpenRouter's data policy for the provider's endpoint; `true` declares the account ZDR so requests that require ZDR may route to this credential even when the shared endpoint retains data; `false` declares it non-ZDR so such requests never route to it. Self-declared and not verified by OpenRouter. Defaults to `null`. | null |
| `disabled` | *boolean* | :heavy\_minus\_sign: | Whether this credential should be created in a disabled state. | false |
| `isByokOnly` | *boolean* | :heavy\_minus\_sign: | Whether OpenRouter's shared endpoints on this provider are removed for every model, including models outside `allowed_models` and after all of your keys for the provider fail. The provider is skipped instead of spending OpenRouter credits. Only valid on non-fallback credentials. Defaults to `false`. | false |
| `isFallback` | *boolean* | :heavy\_minus\_sign: | Whether this credential is treated as a fallback — used only after non-fallback keys for the same provider have been tried. Cannot be combined with `is_byok_only`. | false |
| `isRequired` | *boolean* | :heavy\_minus\_sign: | Whether OpenRouter's shared endpoints on this provider are removed for the models this credential applies to (its `allowed_models`, or every model when `null`). Requests for those models run only on your keys; models outside the allowlist may still fall back to shared capacity on this provider. Defaults to `false`. | false |
| `key` | *string* | :heavy\_check\_mark: | The raw provider API key or credential. This value is encrypted at rest and never returned in API responses. | sk-proj-abc123... |
| `name` | *string* | :heavy\_minus\_sign: | Optional human-readable name for the credential. | Production OpenAI Key |
| `provider` | [models.BYOKProviderSlug](../models/byokproviderslug.mdx) | :heavy\_check\_mark: | The upstream provider this credential authenticates against, as a lowercase slug (e.g. `openai`, `anthropic`, `amazon-bedrock`). | openai |
| `workspaceId` | *string* | :heavy\_minus\_sign: | Optional workspace ID to scope the credential to. When omitted, the credential is created in the account's default workspace; if that default has been deleted, the request returns a 400 and you must pass `workspace_id` explicitly. | 550e8400-e29b-41d4-a716-446655440000 |
