Implementation Guide

Developer documentation

Grok 4.3 Integration Guide

Submit prompts using standard async or real-time streaming Server-Sent Events (SSE).

1. Standard (Async) Endpoint

POST /api/v1/grok-4-3

Returns a request_id immediately. Poll /api/v1/predictions/{id}/result for completion status.

curl -X POST https://muapi.ai/api/grok-4-3 \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Solve this complex logic puzzle step by step.",
    "reasoning_effort": "high"
  }'

2. Streaming (SSE) Endpoint

POST /api/v1/grok-4-3/stream

Returns a chunked Content-Type: text/event-stream stream of server-sent events, ending with data: [DONE].

Common Questions

Frequently asked

Does Grok 4.3 support image inputs?

Yes, Grok 4.3 is a multimodal model. You can supply an optional image_url in the request payload to analyze screenshots, graphs, or photographs.

How is the pricing calculated for Grok 4.3 on Muapi?

Billing is token-based: input tokens cost $2.50 per million, and output tokens cost $5.00 per million. The minimum cost per request is $0.0001. Charges are automatically deducted from your account wallet balance.

Can Grok 4.3 browse the live web?

Yes. If web_search is set to true in the payload, Grok 4.3 utilizes built-in search tools to fetch the latest real-time information from the web.

What is the difference between standard and streaming routes?

The standard route runs asynchronously and returns a request ID, making it ideal for background processing and scripts. The streaming route sends Server-Sent Events (SSE) in real-time, making it best for conversational chat interfaces.
