How this service works

xAI models — chat, web/X search, code execution, image generation/editing, and text-to-speech.

Output

A JSON object containing the Grok model's chat completion response (data field), payment settlement details including settled and authorized USDC amounts, a unique request ID, and a status URL for async tracking.

Example use cases

Real-time X sentiment on a stock

“Search X right now for what people are saying about $NVDA earnings — use Grok grok-4.5, limit to 400 tokens and 3 tool calls, and give me a quick sentiment summary.”

Breaking news research for a newsletter

“I need a quick briefing on the latest developments in the EU AI Act — use Grok with web and X search, grok-4.5 model, up to 600 tokens and 5 tool calls.”

Fact-check a viral X claim

“Can you use Grok's X search to check whether this claim going viral is accurate: 'Apple is acquiring OpenAI' — grok-4.5, 300 tokens max, 2 tool calls.”

When to prefer

Choose this endpoint when you need Grok's chat capabilities specifically augmented with live X (Twitter) and web search data, and you want to pay per-call via x402 USDC micropayments without a subscription. Prefer it over generic Grok chat endpoints when answers require real-time grounding from X posts or current web results. It is particularly useful for agents that need up-to-date social sentiment, breaking news, or recent events that a static model cannot answer reliably.

Side effects

Insufficient USDC balance causes payment failure and request rejection
Invalid or unsupported model ID returns an error
max_tokens not provided causes metered billing rejection (required for x402)
max_tool_calls exceeding 10 or below 1 is rejected
X/web search tool unavailable or rate-limited causing incomplete results
Request timeout if Grok takes too long to complete tool call chains
