The returned model codes are used as the models value in prompt run requests (submitRun) and as the model filter value in the statistics APIs. Some models (`CLAUDE`, `PERPLEXITY`, `GROK`, `DEEPSEEK`) are provided only to organizations granted access under a separate agreement. Organizations without the grant do not see them in this list, and run submissions are rejected with 403 `MODEL_NOT_GRANTED`. Even without the grant, previously collected answers can still be retrieved through the model filter of the statistics APIs. If a model is discontinued, it no longer appears in this list and run submissions are rejected with 400 `MODEL_DISCONTINUED`. No models are currently discontinued. ### Errors | HTTP | Code | Description | | --- | --- | --- | | 401 | `COMMON_UNAUTHORIZED` | API key or access token is missing or invalid | | 402 | `INSUFFICIENT_CREDITS` | The organization's credit balance is lower than the unit price of this request | | 429 | `PLATFORM_RATE_LIMIT_EXCEEDED` | Rate limit exceeded. Wait the number of seconds in the `Retry-After` header, then retry | | 500 | — | Internal server error. Returns `message` and `requestID` without `code` | ## OpenAPI ````yaml openapi.en.json GET /v1/platform/models openapi: 3.1.0 info: description: >- Platform API for external partners. Uses organization API key based authentication. ### Common request limits - The request body size is limited to 2MiB. Exceeding it returns 413 with the `COMMON_REQUEST_BODY_TOO_LARGE` code. - Array parameters and string fields have per-endpoint count and length limits. The limits are stated in each field or parameter description, and violating them returns 400 with the `COMMON_VALIDATION` code. ### Error responses The error response body always has the same three fields regardless of the status code. | Field | Type | Meaning | | --- | --- | --- | | `code` | string | A fixed identifier for the error type. This is the only value clients should branch on. The codes each endpoint returns are listed in the "Errors" table of that API. | | `message` | string | A human-readable, one-line summary of the whole error. There is always exactly one. | | `details` | array of strings | Individual reasons that do not fit in the single `message` line. Even a single reason is returned as an array of length 1, and the field is omitted when there is nothing to include. | - `details` is an array in every error. It is never returned as a string or an object, so no type-based branching is needed. - The wording of `details` is not a fixed contract. Use it only for display and debugging, and do not parse the strings to branch. Branch on `code` instead. - `details` is the only field that carries multiple reasons. There is no `messages` field in the response. - On validation failure (`COMMON_VALIDATION`), `details` contains one `"field: reason"` line per violated field. Example: `{"code":"COMMON_VALIDATION","message":"Data validation failed","details":["keywords: up to 100 items can be entered"]}` - `message` defaults to Korean and is returned in English when you send `Accept-Language: en`. `details` follows the same rule when it carries per-field reasons such as validation failures, but errors that include raw text for diagnostic purposes may contain wording in a language other than the requested one. - Only 500 has a different shape. It returns `message` and a `requestID` to reference when contacting support, without `code`. title: Platform API version: '1.0' servers: - url: https://platform-api.trychainshift.ai/api security: [] tags: - description: >- The top-level account unit that API keys belong to.
