Claude Opus 4.7-Level API Access, Without the Price Tag

Searches for "how to get Claude Opus 4.7 API access" keep climbing — and for good reason. Opus 4.7 remains the reference model for multi-hour autonomous coding runs and the only mainstream model with 128K-token single-pass outputs. It is also the most expensive mainstream API by a wide margin.

Getting Opus 4.7 access

1. Anthropic API direct — pay-as-you-go at list price; usage tiers unlock higher rate limits over time.
2. Managed cloud gateways — some aggregators resell Anthropic models, usually at or above list price.
3. The smarter pattern — use Opus 4.7 only for the slice that needs it, and route everything else to cheaper near-frontier models.

Which slice actually needs Opus?

The routing pattern that saves 80%

from openai import OpenAI
client = OpenAI(base_url="https://aiapi-pro.com/v1", api_key="YOUR_NOVAI_KEY")

def route(task):
    if task.kind in ("long-agent", "massive-output"):
        return call_frontier_directly(task)          # Opus 4.7 via Anthropic
    if task.kind == "code":
        return client.chat.completions.create(
            model="kimi-k2.7-code", messages=task.messages)
    return client.chat.completions.create(
        model="deepseek-v4-pro", messages=task.messages)

Because NovAI is OpenAI-compatible, adding the cheap tier is a one-line base_url change — your OpenAI SDK code, evals and logging all keep working.

Bottom line

Keep Opus 4.7 where it provably wins (long agent runs, giant outputs). Move the rest to DeepSeek V4 / Kimi K2.7-Code and your blended cost drops 70–90% with no user-visible quality change.
