How this service works
GLM 5.2 chat via x402. OpenAI-compatible /v1/chat/completions, streaming supported. Listed as glm-5.2. $0.001 USDC per request on Base/Solana mainnet. See GET /x402/v1/models for the full chat catalog.
Output
Returns an OpenAI-compatible chat.completion JSON object containing the assistant's generated message, finish reason, model identifier ('grok-4.5-high'), and a completion ID. Streaming mode returns server-sent event chunks in the standard OpenAI delta format.
Example use cases
Frontier reasoning for agent pipeline
“I need you to use the Grok 4.5 High model to analyze this legal clause and explain the key obligations and risks it creates for both parties — stream the response as it comes in.”
Pay-per-use LLM without subscription
“Can you call the Grok 4.5 High chat API for me and ask it to write a detailed technical explanation of how transformers work, up to 1000 tokens? I want to pay per request rather than sign up for another subscription.”
Creative writing with high-capability model
“Use Grok 4.5 High to write the opening chapter of a sci-fi short story about an AI waking up on a generation ship — make it around 800 tokens and stream the output so I can read it as it appears.”

Endpoint
POSThttps://x402donghang.duckdns.org/x402/v1/chat/completionsWhen to prefer
Choose this endpoint when you need access to the Grok 4.5 High model specifically — a high-capability frontier LLM — without a standing subscription, paying only $0.01 USDC per request via the x402 protocol on Base or Solana. It is ideal for agents that require sporadic but powerful reasoning, creative generation, or complex instruction-following, especially in crypto-native or agent-to-agent workflows where micropayments are the preferred billing model.
Side effects
- Payment not received or insufficient USDC balance — returns HTTP 402 with payment instructions
- Invalid model name (must be exactly 'grok-4.5-high') — returns 400 or model-not-found error
- Malformed messages array (missing role or content fields) — returns 422 validation error
- max_tokens exceeds model context limit — response truncated or error returned
- Network timeout on long generations — partial response or connection reset
- Upstream xAI API downtime — service may be temporarily unavailable
