Error Handling

Python

import time
from openai import OpenAI, RateLimitError, APITimeoutError, APIConnectionError

client = OpenAI(api_key="your-api-key", base_url="https://aisupermarket.work/v1")

def generate_with_retry(prompt, max_retries=3):
    for attempt in range(max_retries):
        try:
            return client.chat.completions.create(
                model="gemini-2.5-flash",
                messages=[{"role": "user", "content": prompt}],
            ).choices[0].message.content
        except RateLimitError:
            wait = 2 ** attempt
            print(f"Rate limited, retrying in {wait} seconds...")
            time.sleep(wait)
        except APITimeoutError:
            print("Request timed out, retrying...")
        except APIConnectionError as e:
            print(f"Connection error: {e}")
            break
    raise Exception("Request failed after the maximum number of retries")

JavaScript

      const response = await client.chat.completions.create({
        model: "gemini-2.5-flash",
        messages: [{ role: "user", content: prompt }],
      });
      return response.choices[0].message.content;
    } catch (err) {
      if (err instanceof OpenAI.RateLimitError) {
        const wait = 2 ** attempt;
        console.log(`Rate limited, retrying in ${wait} seconds...`);
        await new Promise((r) => setTimeout(r, wait * 1000));
      } else if (err instanceof OpenAI.APIConnectionError) {
        console.error(`Connection error: ${err.message}`);
        break;

        console.log("Request timed out, retrying...");
      }

Common Error Codes

Status Code	Cause	Fix
401	Invalid API Key	Check the Key
429	Rate limit exceeded	Retry with exponential backoff
500	Server-side error	Retry later
503	Model does not exist or is unavailable	Check the model name
