# API-Referenz

One base URL, one bearer token, two surfaces.

## Chat completions

Standard fields are accepted: `model`, `messages`, `temperature`, `top_p`, `max_tokens`, `stream`, `stop`, `presence_penalty`, `frequency_penalty`, `user`, `tools`, `tool_choice`, `response_format`, `seed`.

## LLM EU extensions

A namespaced `llmeu` object in the request body. Official SDKs ignore unknown fields, so adding it never breaks a client.

```
"llmeu": {
  "residency": "eu-hosted" | "eu-owned" | "de" | "any",
  "task": "general" | "coding" | "reasoning" | "translation" | "vision" | "cheap" | "legal-draft" | "rag",
  "retention": "zero",
  "data_class": "public" | "internal" | "confidential" | "restricted",
  "policy_id": "uuid",
  "max_usd_per_1m": 0.5,
  "allow_partners": false
}
```

Nur zero ist als Aufbewahrungsmodus implementiert. Richtlinien k%C3%B6nnen 24h, 7d oder 30d speichern; dies aktiviert keine Speicherung. %C3%9Cberschreitet die Anfrage die Richtlinie, folgt zuerst 403 retention_exceeds_policy; eine erlaubte effektive Aufbewahrung ungleich zero wird mit 501 retention_not_implemented abgelehnt.

## Response

Standard OpenAI shape, plus:

```
{
  "choices": [...],
  "usage": {...},
  "llmeu": {
    "trace_id": "%E2%80%A6",
    "model_used": "%E2%80%A6",
    "model_version": "%E2%80%A6",
    "provider": "%E2%80%A6",
    "endpoint_id": "%E2%80%A6",
    "inference_region": "de-fra",
    "sovereignty_class": "eu_owned_eu_operated",
    "route_reason": "auto routing for task \"coding\" + residency eu-hosted + %E2%80%A6",
    "policy_id": "%E2%80%A6",
    "retention": "zero",
    "cost_estimate_usd": 0.000123
  }
}
```

## Fehler

Die vollst%C3%A4ndige Code-Tabelle mit Status, Typ und Vorgehen steht unter[Fehler](/de/docs/errors/) %E2%80%94 gerendert aus derselben Quelle, die die API verwendet.

## Endpunkte

Jede eingeh%C3%A4ngte Route, mit den n%C3%B6tigen Zugangsdaten, steht unter [Endpunkte](/de/docs/endpoints/).
