Prices are per million tokens. TTFT is the observed time to first token. Selectable routes include the applicable provider-selection markup; fixed routes show the standard model price. Availability and pricing refresh continuously; each model page shows the live provider comparison.

Using LongCat via the API

Call a model served by LongCat using its displayed model ID, including the provider suffix when selection is supported.

cURL

curl https://api.nano-gpt.com/api/v1/chat/completions \
  -H "Authorization: Bearer $NANOGPT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "longcat-2.0:longcat",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

For models with provider selection, append :longcat to the model ID, set "provider": "longcat" in the request body, or send an X-Provider: longcat header. Explicit provider selection adds a route-specific markup over that provider's base price; the prices in the table above already include it. Models without provider selection use the displayed model ID without a provider suffix or selection surcharge.

See the API documentation for provider preferences, price-aware routing, and error behavior.
