Who This Is For

This guide is for small teams, small companies, paid power users, and channel partners that already have real API traffic, basic engineering ability, and a need for long-term stable calls. It is not aimed at casual trials, low-budget testing, or high-support manual onboarding.

Pricing Groups

  • Welfare group: official price at 15% of list price
  • Official-transfer group: official price at 60% of list price
  • Stable official group: official price at 80% of list price

Why Use a Claude API Gateway

Many teams want Claude for coding assistants, writing workflows, summarization, document extraction, and internal AI tools, but they also need practical routing, fallback, and cost control. ViralAPI gives these teams a single OpenAI-compatible endpoint so existing Chat Completions clients can route calls to Claude, GPT, and Gemini without rewriting every integration.

Common production requirements include:

  • Stable Claude access for real application traffic
  • OpenAI-compatible request and response shape
  • Fallback across Claude, GPT, and Gemini families
  • Cost-aware model selection by use case
  • Easier internal migration between model providers

API Pattern

Use the same style as an OpenAI Chat Completions client. Replace the base URL with the ViralAPI endpoint from your account console and keep API keys in environment variables.

curl https://viralapi.ai/v1/chat/completions \
  -H "Authorization: Bearer $VIRALAPI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-4",
    "messages": [
      {"role": "system", "content": "You are a concise technical assistant."},
      {"role": "user", "content": "Summarize this API error and suggest a fix."}
    ],
    "temperature": 0.2
  }'

Python Example

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["VIRALAPI_API_KEY"],
    base_url="https://viralapi.ai/v1",
)

response = client.chat.completions.create(
    model="claude-sonnet-4",
    messages=[
        {"role": "system", "content": "You help engineering teams debug API integrations."},
        {"role": "user", "content": "Explain why a 429 happens and how to retry safely."},
    ],
    temperature=0.2,
)

print(response.choices[0].message.content)

Node.js Example

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.VIRALAPI_API_KEY,
  baseURL: "https://viralapi.ai/v1",
});

const response = await client.chat.completions.create({
  model: "claude-sonnet-4",
  messages: [
    { role: "system", content: "You write production-grade API integration notes." },
    { role: "user", content: "Draft retry handling for timeout and rate-limit errors." },
  ],
  temperature: 0.2,
});

console.log(response.choices[0].message.content);

Error Handling

Production callers should handle transient failures explicitly:

  • 401: check whether the API key is present, active, and loaded from the right environment.
  • 403: verify account permissions, model access, and billing group availability.
  • 408 or timeout: retry with exponential backoff and request id logging.
  • 429: reduce concurrency, add queueing, and retry after a delay.
  • 5xx: retry idempotent requests and consider fallback to another model group.

Suggested Routing Strategy

Use a stable model for core workflows, a cost-aware model for batch jobs, and fallback when latency or rate limits affect a single provider. For example:

  • Claude for coding, long-form reasoning, and structured technical writing
  • GPT for broad assistant workflows and tool calling compatibility
  • Gemini for backup capacity, multimodal tasks, or selective cost control

FAQ

1. What is ViralAPI?

ViralAPI is an OpenAI-compatible API gateway for teams that need stable access to Claude, GPT, and Gemini models from one integration path.

2. Do I need to rewrite my OpenAI SDK code?

Usually no. Most teams only change the base URL, model name, and API key, then test response handling.

3. Can I use ViralAPI for production traffic?

Yes, it is intended for users with real call volume, basic technical ability, and long-term stable API needs.

4. Does this guide include a real API key?

No. Store your own key in VIRALAPI_API_KEY or a secrets manager. Never commit keys to GitHub.

5. How should I choose a pricing group?

Use the welfare group for suitable discounted access, the official-transfer group when you need a balance of official-channel pricing and availability, and the stable official group when stability is the main priority.

6. Who should contact ViralAPI?

Small B teams, small companies, paid power users, and channel or bulk buyers with real API demand are the best fit.
