Common Errors and Fixes

Error 1: 401 Unauthorized - Invalid API Key

Symptom: API returns {"error": {"message": "Invalid API key provided", "type": "invalid_request_error"}}

# Incorrect - Common mistake using wrong header format
response = requests.post(
    f"{BASE_URL}/chat/completions",
    headers={"X-API-KEY": API_KEY},  # WRONG HEADER
    json=payload
)


CORRECT FIX - Use Authorization Bearer header

response = requests.post(
    f"{BASE_URL}/chat/completions",
    headers={
        "Authorization": f"Bearer {API_KEY}",
        "Content-Type": "application/json"
    },
    json=payload
)

Error 2: 429 Rate Limit Exceeded

Symptom: Chinese text generation fails intermittently with rate limit errors during high-volume batches

import time
import requests
from requests.adapters import HTTPAdapter
from urllib3.util.retry import Retry

def rate_limit_resilient_request(url: str, headers: dict, payload: dict, max_retries: int = 5) -> dict:
    """
    Handle rate limiting with exponential backoff for high-volume Chinese content generation.
    """
    session = requests.Session()
    retry_strategy = Retry(
        total=max_retries,
        backoff_factor=2,
        status_forcelist=[429, 500, 502, 503, 504]
    )
    adapter = HTTPAdapter(max_retries=retry_strategy)
    session.mount("https://", adapter)
    
    for attempt in range(max_retries):
        response = session.post(url, headers=headers, json=payload, timeout=60)
        
        if response.status_code == 200:
            return response.json()
        elif response.status_code == 429:
            wait_time = 2 ** attempt
            print(f"Rate limited. Waiting {wait_time}s before retry {attempt + 1}/{max_retries}")
            time.sleep(wait_time)
        else:
            raise Exception(f"Request failed: {response.status_code} - {response.text}")
    
    raise Exception("Max retries exceeded for rate-limited endpoint")

Error 3: Unicode Encoding Issues in Chinese Response

Symptom: Chinese characters display as garbled unicode sequences or question marks in terminal output

# INCORRECT - Default encoding may mishandle Chinese characters
result = requests.post(url, headers=headers, json=payload)
print(result.text)  # Garbled output possible


CORRECT FIX - Explicitly handle UTF-8 encoding

result = requests.post(url, headers=headers, json=payload)
result.encoding = 'utf-8'
chinese_content = result.json()["choices"][0]["message"]["content"]
print(chinese_content)  # Proper Chinese display


Alternative: Direct string handling for Claude responses

raw_response = result.text
decoded_content = raw_response.encode('utf-8').decode('utf-8')
print(decoded_content)

Error 4: Model Name Mismatch

Symptom: Error message: "model not found" or "invalid model parameter"

# INCORRECT - Using official model identifiers directly
payload = {"model": "claude-sonnet-4-20250514", ...}  # May fail


CORRECT - Verify exact model identifiers for HolySheep relay

SUPPORTED_MODELS = {
    "claude": ["claude-sonnet-4-20250514", "claude-opus-4-20250514"],
    "gemini": ["gemini-2.5-flash", "gemini-2.0-pro"],
    "openai": ["gpt-4.1", "gpt-4-turbo"],
    "deepseek": ["deepseek-v3.2", "deepseek-coder-v2"]
}

def validate_model(model: str) -> str:
    """Validate and normalize model name for HolySheep API."""
    all_models = [m for models in SUPPORTED_MODELS.values() for m in models]
    if model in all_models:
        return model
    raise ValueError(f"Model '{model}' not supported. Use: {all_models}")


Usage

payload = {"model": validate_model("claude-sonnet-4-20250514"), ...}
