VikingBot API

When OpenViking Server starts with --with-bot, it proxies VikingBot's core interaction endpoints below /bot/v1. These endpoints return 503 when Bot is not enabled.

Code entry points:

• openviking/server/routers/bot.py - OpenViking Server proxy and identity forwarding
• bot/vikingbot/channels/openapi.py - VikingBot Gateway routes
• bot/vikingbot/channels/openapi_models.py - request, response, and SSE event models

API Reference

health()

Check whether the Bot Gateway is available.

HTTP API

curl http://localhost:1933/bot/v1/health

Response Example

{
  "status": "healthy",
  "version": "0.1.0",
  "timestamp": "2026-07-24T09:00:00"
}

chat()

Send text and/or images and wait for the complete reply. Omit session_id to create a new session.

Field	Type	Required	Default	Description
message	string	Conditional	""	User text; required when images is empty
images	array	Conditional	[]	Up to four OpenAI-style image_url parts; required when message is empty
session_id	string	No	Generated	Existing session to continue
context	array	No	null	Additional messages containing role and content
need_reply	boolean	No	true	Whether the Bot should reply
disabled_tools	string[]	No	[]	Tool names disabled for this request
channel_id	string	No	null	Multi-channel routing identifier

HTTP API

curl -X POST http://localhost:1933/bot/v1/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-key" \
  -d '{"message":"Summarize my project progress","session_id":"optional-session-id"}'

Images may use an accessible HTTPS URL or an inline Base64 data URL:

curl -X POST http://localhost:1933/bot/v1/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-key" \
  -d '{
    "message": "Describe this image",
    "images": [{
      "type": "image_url",
      "image_url": {
        "url": "https://example.com/photo.png"
      }
    }]
  }'

Inline Base64 images support JPEG, PNG, GIF, and WebP. Each decoded inline image is limited to 10 MiB; inline SVG and mismatched MIME signatures are rejected. For HTTPS URLs, the Gateway validates the URL structure but does not fetch or inspect the remote resource, so remote format support and related errors are provider-specific. Local filesystem paths are rejected. The optional detail field accepts auto, low, or high; omit it for maximum provider compatibility.

CLI

ov chat -m "Summarize my project progress"

Response Example

{
  "session_id": "session-id",
  "response_id": "response-id",
  "message": "Here is the current project summary…",
  "events": null,
  "relevant_memories": null,
  "token_usage": {
    "prompt_tokens": 120,
    "completion_tokens": 42,
    "total_tokens": 162
  },
  "timestamp": "2026-07-24T09:00:00"
}

chat_stream()

Return reasoning, tool calls, content deltas, and the final response as Server-Sent Events. The request fields are the same as chat(); the Gateway enables streaming automatically.

HTTP API

curl -N -X POST http://localhost:1933/bot/v1/chat/stream \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-key" \
  -d '{"message":"Analyze the current knowledge base"}'

CLI

ov chat -m "Analyze the current knowledge base"

SSE Response Example

Each message uses data: <json> format. The X-VikingBot-Session-ID response header contains the session ID.

data: {"event":"reasoning_delta","data":"Inspecting the knowledge base…","timestamp":"2026-07-24T09:00:00"}

data: {"event":"content_delta","data":"The knowledge base contains","timestamp":"2026-07-24T09:00:01"}

data: {"event":"response","data":{"content":"The knowledge base contains…","response_id":"response-id"},"timestamp":"2026-07-24T09:00:02"}

event can be reasoning, reasoning_delta, tool_call, tool_result, content_delta, iteration, or response.

feedback()

Submit explicit feedback for an existing assistant response.

Field	Type	Required	Description
session_id	string	Yes	Session containing the target response
response_id	string	Yes	Target assistant response ID
feedback_type	string	Yes	thumb_up, thumb_down, or rating
feedback_score	number	Conditional	Required when feedback_type=rating
feedback_reason	string	No	Feedback reason label
feedback_text	string	No	Free-form feedback
channel_id	string	No	Multi-channel routing identifier

HTTP API

curl -X POST http://localhost:1933/bot/v1/feedback \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-key" \
  -d '{
    "session_id":"session-id",
    "response_id":"response-id",
    "feedback_type":"thumb_up"
  }'

Response Example

{
  "accepted": true,
  "response_id": "response-id",
  "session_id": "session-id",
  "feedback_type": "thumb_up",
  "feedback_delay_sec": 8.42,
  "timestamp": "2026-07-24T09:00:08"
}

A missing target response returns 404. Rating feedback without feedback_score returns a request validation error.

Client Scope

The standard OpenViking Python, TypeScript, and Go SDKs do not currently wrap the Bot proxy. Chat is available through the ov CLI and HTTP. The VikingBot Gateway also exposes Session and Channel APIs; see the VikingBot documentation.
