API reference

Chat API

Chat completions and model discovery on the organisation's approved processing. Needs a personal key with chat:complete; an organisation integration key gets 403 integration_not_permitted.

Base URL
https://api.komplai.dk

List the permitted chat models

GET /v1/models

The models this key may use for POST /v1/chat/completions, with their context and output limits, the reasoning efforts they take and, in komplai's EU cloud, the provider's token rates. processing chooses which processing to list: komplai's local infrastructure, komplai's EU cloud or one of your organisation's own connections. It sends no text and runs no model. Needs a personal key with chat:complete.

Scopes
chat:complete
Try it

Calls are real: komplai processes what you send, each call counts towards your key's limits, and processing in EU cloud counts towards your organisation's monthly AI spending cap. Use test data.

A key that starts with kp_live_. It stays on this page until you leave it and is sent only to api.komplai.dk.

Parameters

Query parameters

  • processing string

    Which processing to list. komplai-local: komplai's local infrastructure in Denmark, with no AI charge (local is accepted too). eu-cloud: komplai's EU cloud, when your organisation has EU processing approved for Chat; usage is metered at the provider's price and counts towards the organisation's monthly AI spending cap. connection:<id>: one of your organisation's own connections that its administrator has made available through the API, shown with its value on the hub's AI processing page; the organisation pays the provider itself, and the usage does not count towards the cap. Leave it out to list your organisation's Chat processing: local infrastructure, or EU cloud when that is what your organisation's Chat uses.

    Pattern
    ^(komplai-local|local|eu-cloud|connection:[0-9A-Fa-f]{8}-[0-9A-Fa-f]{4}-[0-9A-Fa-f]{4}-[0-9A-Fa-f]{4}-[0-9A-Fa-f]{12})$

Responses

200 OK

The models this key may use at that processing. On local infrastructure: the models your organisation has switched on, or every selectable model while it has switched on none. In EU cloud: the models on your organisation's EU route, with their rates. For a connection: the one model or router it names. The list grants no access of its own.

Create a chat completion

POST /v1/chat/completions

An OpenAI-compatible chat completion with text only, returned whole (stream false). It runs where processing says: komplai's local infrastructure in Denmark, komplai's EU cloud when your organisation has it approved for Chat, or one of your organisation's own connections; without processing, where your organisation's Chat runs. The API never moves a call to other processing or another model, also not when the chosen one fails. At most 32 messages and 80,000 UTF-16 code units of text; the model has 120 seconds to answer. In EU cloud, usage is metered at the provider's price and counts towards the organisation's monthly AI spending cap; the call stops when the cap, the organisation's own limit or your personal limit is reached. Needs a personal key with chat:complete.

Refused for now. Wait the seconds in Retry-After before you try again.

Error codes

  • rate_limited Too many requests: the per-minute limit of the person behind a personal key (shared with that person's other keys and use of the hub) or of the integration behind an organisation integration key (shared by its keys), the organisation's (120), the API's (300) or the per-IP network limit. Wait Retry-After seconds.
  • ai_credit_exhausted The organisation's monthly AI spending cap for EU cloud is reached, or its own lower limit, or on a pilot the pilot's total allowance. Local processing keeps working.
  • person_ai_credit_exhausted Your personal AI limit is reached (personal keys only).
  • connection_rate_limited The provider behind the connection refused the call for now.

Headers

  • Request-Id string required

    This request's id: your X-Request-Id when you sent one valid UUID, otherwise a new UUID. An error body repeats it as request_id.

    Format
    uuid
  • Retry-After integer

    Seconds to wait before trying again (at most 60). Sent with rate_limited and with a provider's own limit; ai_credit_exhausted and person_ai_credit_exhausted carry none, because waiting does not lift a spending limit.

    Value
    1 to 60
  • x-ratelimit-limit integer

    Requests per minute allowed from your IP address (the per-IP network limit).

  • x-ratelimit-remaining integer

    Requests left in the current minute from your IP address.

  • x-ratelimit-reset integer

    Seconds until the per-IP window resets.

502 Bad Gateway
