How this service works
GLM-5.3 API (zai/glm-5.3): LLM inference via OpenAI-compatible chat completions, pay per call in USDC on Base with x402. No API key, no account. Suited for AI agents and scripts that need GLM-5.3 on demand. When listed, this request cost 30% less than the same request on BlockRun. Streaming and function calling supported. Exact price in the 402 quote before payment; automatic refund if the model fails to answer.
Output
Returns an OpenAI-compatible chat.completion JSON object containing the assistant's reply message, the model name (zai/glm-5.3), token usage breakdown (prompt, completion, total tokens), finish reason (e.g. 'stop'), and a unique completion ID and creation timestamp.
Example use cases
Anonymous LLM call with crypto payment
“I need to call the GLM-5.3 language model to answer a customer question — 'What are the main benefits of solar energy?' — without creating any account. Just pay per request with USDC and give me the reply.”
Agent-to-agent text reasoning task
“Have the GLM-5.3 model reason through this logic puzzle and return its answer: 'If all cats are mammals and some mammals are pets, can we conclude that some cats are pets? Explain step by step.'”
Multilingual content generation
“Use the GLM-5.3 model to translate and rephrase this product description into formal Chinese: 'Our wireless earbuds deliver studio-quality sound with 30-hour battery life.' Return the completed text.”

Endpoint
POSThttps://agent402-arb.rosariovitale0096.workers.dev/llm/glm-5.3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need GLM-5.3 specifically (ZhipuAI's model), want an OpenAI-compatible API with no account or API key setup, and prefer per-request USDC micropayment billing on Base. It is ideal for anonymous, one-off inference calls or agents that manage their own crypto wallets via x402.
Side effects
- Payment failure: x402 payment not completed or insufficient USDC balance, returns 402 Payment Required
- Invalid request body: missing required 'messages' field or malformed JSON returns 400 Bad Request
- Model unavailable: GLM-5.3 backend unreachable returns 503 or timeout
- Rate limit exceeded on the Cloudflare Worker returns 429
- Context length exceeded: prompt too long for GLM-5.3 context window
