# API Changelog

> Changes to the OpenRouter API, generated from the OpenAPI specification on every release.

Entries on this page are generated automatically from [OpenAPI specification](/docs/api_reference/overview.md) diffs when releases ship. Breaking changes are reviewed by a human before publication. See [API Versioning](/docs/api_reference/versioning.md) for what counts as a breaking change and how deprecations are announced. Endpoint paths are shown relative to the API base URL (`https://openrouter.ai/api/v1`).

## Breaking changes

* `CreateEndUserRequest`: schema object removedAction required
  * Renamed to `CreateExternalUserRequest`; the shape is unchanged, so HTTP callers need no change. The Python SDK (`openrouter` 1.3.70 and later) and TypeScript SDK (`@openrouter/sdk` 1.5.0 and later) replace the `CreateEndUserRequest` model with `CreateExternalUserRequest`.
* `EndUser`: schema object removedAction required
  * Renamed to `ExternalUser`; the shape is unchanged, so HTTP callers need no change. The Python SDK (`openrouter` 1.3.70 and later) and TypeScript SDK (`@openrouter/sdk` 1.5.0 and later) replace the `EndUser` model with `ExternalUser`.
* `EndUserResponse`: schema object removedAction required
  * Renamed to `ExternalUserResponse`; the shape is unchanged, so HTTP callers need no change. The Python SDK (`openrouter` 1.3.70 and later) and TypeScript SDK (`@openrouter/sdk` 1.5.0 and later) replace the `EndUserResponse` model with `ExternalUserResponse`.
* `ListEndUsersResponse`: schema object removedAction required
  * Renamed to `ListExternalUsersResponse`; the shape is unchanged, so HTTP callers need no change. The Python SDK (`openrouter` 1.3.70 and later) and TypeScript SDK (`@openrouter/sdk` 1.5.0 and later) replace the `ListEndUsersResponse` model with `ListExternalUsersResponse`.
* `UpdateEndUserRequest`: schema object removedAction required
  * Renamed to `UpdateExternalUserRequest`; the shape is unchanged, so HTTP callers need no change. The Python SDK (`openrouter` 1.3.70 and later) and TypeScript SDK (`@openrouter/sdk` 1.5.0 and later) replace the `UpdateEndUserRequest` model with `UpdateExternalUserRequest`.
* `/end-users`: endpoint object removedAction required
  * Requests to `/end-users` continue to work and are forwarded to [`/external-users`](/docs/api/api-reference/external-users/list-registered-external-users), so HTTP callers need no change. In the Python SDK (`openrouter` 1.3.70 and later), switch `client.end_users` to `client.external_users`; the old namespace was removed. In the TypeScript SDK (`@openrouter/sdk` 1.5.0 and later), use `externalUsers` for new code; `endUsers` remains available as a compatibility alias. Method names (`list`, `create`, `get`, `update`, `delete`) are unchanged.
* `/end-users/{user}`: endpoint object removedAction required
  * Requests to `/end-users/{user}` continue to work and are forwarded to [`/external-users/{user}`](/docs/api/api-reference/external-users/get-a-registered-external-user), so HTTP callers need no change. Python SDK users switch to `external_users`; TypeScript SDK users can migrate to `externalUsers` while `endUsers` remains available as a compatibility alias, as described on the `/end-users` entry above.
* [`GET /interns/{internId}/icon`](/docs/api/api-reference/interns/get-an-interns-icon): content `image/jpeg` object removedNo action needed
  * The response is now declared as `image/*`. The bytes served and their `Content-Type` headers are unchanged.
* [`GET /interns/{internId}/icon`](/docs/api/api-reference/interns/get-an-interns-icon): content `image/png` object removedNo action needed
  * The response is now declared as `image/*`. The bytes served and their `Content-Type` headers are unchanged.
* \$.tags: End Users object removedNo action needed
  * Documentation tag renamed to External Users. No API change.
* [`POST /messages`](/docs/api/api-reference/anthropic-messages/create-a-message): x-speakeasy-sse-sentinel `[DONE]` object removedAction required
  * Streams now end at the `message_stop` event and no longer send a trailing `data: [DONE]` frame, matching the Anthropic Messages protocol. Clients that detected the end of a `/messages` stream by waiting for `[DONE]` must terminate on `message_stop` on success, and on the `error` event or stream closure on failure. Anthropic's official SDKs already expect this.
* `BulkAssignMembersRequest`: `member_user_ids` now accepts at most 500 itemsAction required
  * Requests with more than 500 member user IDs now return `400`; previously they were accepted. Split larger lists into batches of 500 or fewer, matching the existing limit on the key assignment endpoints.
  * Used by [`POST /guardrails/{id}/assignments/members`](/docs/api/api-reference/guardrails/bulk-assign-members-to-a-guardrail)
* `BulkUnassignMembersRequest`: `member_user_ids` now accepts at most 500 itemsAction required
  * Requests with more than 500 member user IDs now return `400`; previously they were accepted. Split larger lists into batches of 500 or fewer, matching the existing limit on the key assignment endpoints.
  * Used by [`POST /guardrails/{id}/assignments/members/remove`](/docs/api/api-reference/guardrails/bulk-unassign-members-from-a-guardrail)
* `InternDaemonAccess`: required `viewer` property addedAction required
  * Used by [`GET /interns/{internId}/daemon`](/docs/api/api-reference/interns/get-an-interns-daemon-access), [`GET /interns/{internId}/daemon-access`](/docs/api/api-reference/interns/get-an-interns-daemon-access-deprecated-alias)

## Breaking changes

* `FileMetadata`: schema object removedNo action needed
* `FileDeleteResponse`: discriminator `discriminator` object addedAction required
  * HTTP clients: no change. Requests without a vendor SDK still get the OpenRouter shape (`_shape: "openrouter"`) with the same fields as before. Typed SDK clients: this response type is now a union discriminated by `_shape`. In the TypeScript SDK, the field is named `shape`, so check `shape === "openrouter"` before reading OpenRouter fields such as `id` and `type`.

## Breaking changes

* `FusionCallAnalysisInProgressEvent`: required `analyst_model` property addedNo action needed
  * **No action required for existing consumers.** `analyst_model` replaces `judge_model` in this streaming event; `judge_model` is retained as a deprecated alias that always carries the same value.
  * Used by [`POST /responses`](/docs/api/api-reference/responses/create-a-response)
* \$.tags: responses object removedNo action needed
  * **No action required.** The `responses` OpenAPI tag was renamed to `Responses` for consistent Title Case across the API Reference. This is a documentation-grouping change only: `POST /api/v1/responses` and its schemas are unchanged, SDK namespaces are unchanged (`client.responses.send()` in TypeScript and Python, `Sdk.Responses.Send()` in Go), and endpoint documentation URLs are unchanged.

## Breaking changes

* [`POST /responses`](/docs/api/api-reference/responses/create-a-response): tags `beta.responses` property removedNo action needed
  * **Migration: no action for HTTP clients.** The Responses API is now GA. `beta.responses` was an OpenAPI grouping tag and SDK namespace, never a URL. `POST /api/v1/responses` and its request and response schemas are unchanged, so raw HTTP callers and OpenAI-compatible clients (including the OpenAI Agents SDK) need no changes. The endpoint now appears under **Responses** instead of **Beta responses** in the API Reference.
  * **Migration for SDK users: optional until sunset.** The canonical namespace is now `responses`, with `client.responses.send()` (TypeScript, Python) and `client.Responses.Send()` (Go). The `beta.responses` namespace, and TypeScript's `betaResponsesSend` standalone function, keep working as deprecated aliases; their removal will be announced here with a sunset date before it ships.
* \$.tags: beta.responses object removedNo action needed
  * Same change as above at the specification level: the `beta.responses` tag definition is gone from `$.tags`.
