Same code as the OpenAI SDK — change the base URL and key, pick a model id:
from openai import OpenAI
client = OpenAI(
base_url="https://api.airforce/v1",
api_key="YOUR_KEY",
)
resp = client.chat.completions.create(
model="claude-3-haiku",
messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)Frequently asked questions
- How do I use Claude models through Api.Airforce?
- Point any OpenAI-compatible client at https://api.airforce/v1 and set the model id (for example "claude-3-haiku"). Your existing OpenAI SDK works unchanged — you only swap the base URL and API key. The same key also speaks the Anthropic Messages API.
- Are Claude models free?
- Claude models are premium — you add credits (a monthly plan or a pay-as-you-go top-up) to call them. A free account can still use the open free-tier models from other families at $0.
- How much do Claude models cost on Api.Airforce?
- Billing is pay-as-you-go per token, at rates that sit well below the official APIs. The exact per-model input and output prices are listed in the table above and update automatically as upstream prices change.
- Which Claude models are available?
- Currently 19 Claude models, including Claude 3 Haiku, Claude 3 Opus, Claude 3.5 Haiku. The catalog is refreshed as new models launch, so the list above is always current.
