Claude API pricing
Claude API at a Lower Cost
Access Claude Sonnet 4.6, Opus 4.8, and Opus 4.7 through one OpenAI-compatible gateway — listed at roughly 40% below common Anthropic reference rates on supported models.
Use Sonnet and Opus through the same Chat Completions endpoint as GPT. Change your API key, base URL, and model id — no separate Anthropic SDK required for most apps.

Three values change: API key, base URL, model id. Everything else stays the same.
Before (official Anthropic)
from anthropic import Anthropic
client = Anthropic(api_key="YOUR_ANTHROPIC_API_KEY")
message = client.messages.create(
model="claude-sonnet-4-6",
max_tokens=1024,
messages=[{"role": "user", "content": "Review this function for bugs."}],
)After (LumeAPI)
from openai import OpenAI
client = OpenAI(

base_url="https://api.lumeapi.site/v1",
)
response = client.chat.completions.create(

Trust & billing
Are these real Claude models?
LumeAPI routes to catalog model IDs such as claude-sonnet-4-6 and claude-opus-4-8. The id in your request is what appears in usage logs and billing.
Will you swap Sonnet for a cheaper model?
No. Your payload specifies the model id. We do not silently substitute models. If a model is unavailable, you receive an error response.
How am I billed?
USD wallet debited per successful call. Input and output tokens are metered separately at published Sonnet and Opus rates.
Is LumeAPI affiliated with Anthropic?
No. LumeAPI is an independent third-party gateway. You are responsible for compliance and how outputs are used in your product.
Built for these workloads
Coding & refactoring
Sonnet 4.6 balances quality and cost for daily IDE copilots. Opus 4.8 handles harder architecture reviews when you need maximum reasoning depth.
Long-document analysis
Claude excels at structured extraction over large inputs. Lower per-token rates reduce the cost of sending full PDFs and conversation history each turn.
Multi-step agents
Agents that call Claude repeatedly benefit from 40% lower list rates on every hop — measure cost per completed task, not per request.
Enterprise copilots
Route internal workflows through one LumeAPI key and wallet. Swap between Sonnet and Opus by changing the model id without new vendor onboarding.
FAQ
Can I use the Anthropic SDK with LumeAPI?
Most teams migrate faster with the OpenAI SDK or compatible frameworks — set base_url to https://api.lumeapi.site/v1 and use our catalog Claude model ids. Test tool calling and streaming in staging first.
Sonnet vs Opus — which should I start with?
Sonnet 4.6 is the default for coding, chat, and agents where cost matters. Opus 4.8 is for hardest reasoning tasks where output quality justifies higher per-token spend.
Does streaming work on Claude models?
Yes on supported entries — POST /v1/chat/completions with stream: true. Validate resume behavior and error handling before production cutover.
What about Anthropic Batch or prompt caching?
Provider-native Batch jobs and Anthropic-specific caching may still require the official platform. LumeAPI focuses on real-time Chat Completions at lower catalog list rates.
Can I run Anthropic and LumeAPI in parallel?
Yes. Use environment variables for base URL and model id. Shadow traffic on LumeAPI, compare quality and latency, then shift volume gradually.
Where do I find exact model ids?
Every Claude model has a detail page under /models with pricing, curl examples, and integration docs. Use the id exactly as listed.
