API-Dokumentation

Gemini API

Gemini 3.5–3.8 Flash and Gemini 4 Argon use /chat/completions. For Argon, use model ID google/gemini-4-argon. GET /models lists published models. For an unlisted model configured by your account administrator, use the exact model ID they provide with the same endpoint.

curl "https://tokenhub.store/api/v1/chat/completions" \
  -H "Authorization: Bearer th-your-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "google/gemini-3.8-flash",
    "messages": [{"role": "user", "content": "Hello"}],
    "reasoning_effort": "low",
    "max_tokens": 1024,
    "stream": true
  }'

Supports streaming, system instructions, function calling, and base64 image data URLs. reasoning_effort accepts low, medium, or high; max_tokens includes thinking tokens.

For multi-turn tools, keep the complete assistant message, including tool_calls.extra_content or content_blocks, so thought signatures are preserved. Native Gemini endpoints are not exposed by TokenHub.

Gemini Flash and Argon output usage includes thinking tokens. Cached input is counted at the configured cache-read rate when available. See the model catalog for current prices; confirm rates for unlisted models with your account administrator.

Responses API: Streaming und Abrechnung

Bei POST /v1/responses kennzeichnet response.completed eine abgeschlossene Antwort. Das anschließende Schließen der Verbindung macht daraus keinen abgebrochenen Auftrag.

Gemeldete Tokenzahlen, einschließlich null, haben Vorrang vor Schätzungen. Nur fehlende Werte werden geschätzt. Bei einem vorzeitigen Abbruch können bereits verarbeitete Tokens berechnet werden.

Account management API

Generate an access token in Settings → Account information. Send Authorization: Bearer YOUR_ACCESS_TOKEN and TokenHub-User: YOUR_USER_ID. New-Api-User is also accepted; if both user headers are supplied, they must match. Open settings

Access tokens manage your account. Continue using th- API keys for model requests.

export TOKENHUB_ACCESS_TOKEN="YOUR_ACCESS_TOKEN"
export TOKENHUB_USER_ID="YOUR_USER_ID"

curl "https://tokenhub.store/api/balance" \
  -H "Authorization: Bearer $TOKENHUB_ACCESS_TOKEN" \
  -H "TokenHub-User: $TOKENHUB_USER_ID"

curl "https://tokenhub.store/api/keys" \
  -H "Authorization: Bearer $TOKENHUB_ACCESS_TOKEN" \
  -H "TokenHub-User: $TOKENHUB_USER_ID" \
  -H "Content-Type: application/json" \
  -d '{"name":"My application","spendLimit":10}'

curl --get "https://tokenhub.store/api/v1/billing/usage" \
  -H "Authorization: Bearer $TOKENHUB_ACCESS_TOKEN" \
  -H "TokenHub-User: $TOKENHUB_USER_ID" \
  --data-urlencode "apiKeyId=YOUR_API_KEY_ID" \
  --data-urlencode "model=alibaba/qwen-turbo" \
  --data-urlencode "startDate=2026-09-07T00:00:00Z" \
  --data-urlencode "endDate=2026-09-08T00:00:00Z" \
  --data-urlencode "page=1" \
  --data-urlencode "limit=20"

Usage filters: apiKeyId is the ID returned by /api/keys, not the th- secret. model matches the full model ID exactly. Send startDate and endDate together as ISO timestamps with a timezone (inclusive boundaries). page defaults to 1; limit defaults to 20, maximum 100. Summary covers all matching records. Omit apiKeyId to query the account. An unknown key or a key owned by another account returns 404. API keys retain their existing account-wide billing access. /api/usage also accepts start_date/end_date, one-sided ranges, limit (default 100, maximum 1000), and offset (default 0).

Create: name=My application, spendLimit=10; omit spendLimit for the shared wallet. PATCH accepts name, isActive, and action (set_limit, add_budget, clear_limit, reset_spent); set_limit/add_budget also need a non-negative value. set_limit resets spent; add_budget preserves spent for an existing cap. GET /api/keys/:id returns the full model key. Deleting a key removes its UsageLog association; use isActive:false to retain usage filtering by key.

One active access token per account. It remains valid until regenerated or revoked; the database stores only its hash. Token lifecycle endpoints GET/POST/DELETE /api/user/access-token require a browser login. Tokens cannot manage their own lifecycle or authorize admin, password, account-deletion, or model-generation endpoints. Invalid tokens or mismatched user IDs return 401. Existing browser-session authentication continues to work.
