How do you call the claude-opus-5 API?

Migration is essentially free: change base_url and api_key, and leave the rest of your code untouched.

1. Fetch the current pricing response：Query `https://api.openlux.ai/api/pricing` and use the live response as the source for current listed values.
2. Find the model entry：Locate the entry whose model ID is `claude-opus-5`.
3. Calculate the applicable price：Multiply the input, output, or cache-hit base price by the multiplier assigned to the account group.
4. Validate runtime behavior：Measure context handling, time to first token, and API compatibility in your own environment before relying on them.
5. Integrate after verification：Use the verified model ID and the integration details available in the account or platform documentation.

Complete code example

import json
from urllib.request import urlopen

url = "https://api.openlux.ai/api/pricing"
with urlopen(url) as response:
    pricing = json.load(response)

# Print every matching occurrence without assuming the response schema.
def walk(value):
    if isinstance(value, dict):
        if value.get("model") == "claude-opus-5" or value.get("id") == "claude-opus-5":
            print(json.dumps(value, indent=2, ensure_ascii=False))
        for child in value.values():
            walk(child)
    elif isinstance(value, list):
        for child in value:
            walk(child)
