# GEDX402 GLM-5.2 LLM via x402

> GEDX402 GLM-5.2 LLM via x402 is a paid API for AI agents from llm.gedx402.com, paid per call via x402, $0.12/call, status unknown (last checked 2026-09-14).

Run multi-turn chat completions against the GLM-5.2 language model, paying per-call with USDC on-chain via x402 — no API keys required.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability gedx402-glm-5-2-llm-via-x402-dee0fd83
```

Example prompt: Using the GLM-5.2 model on GEDX402 (pay-per-call with USDC, no API key), send this conversation and get a reply — system: 'You are a helpful assistant.', user: 'Explain quantum entanglement in simple terms.', and limit the response to 512 tokens.

## When to prefer this

Choose this endpoint when you need per-call LLM inference with no API key or subscription — ideal for agents that want to pay for exactly what they use in USDC on Base, Polygon, Arbitrum, World, or Solana. Prefer it specifically when you want the GLM-5.2 model (a capable bilingual Chinese/English model) via Cloudflare Workers AI infrastructure without account management overhead.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Invalid message role (not system/user/assistant) causes schema validation error
- max_tokens exceeding 4096 is rejected
- Empty or malformed messages array returns an error
- Network timeout if Workers AI backend is slow
- Unsupported payment chain causes transaction failure

## How this service works

x402 workers ai. pay with usdc on base, polygon, arbitrum, world, or solana. no api keys.

## Output

A JSON object containing the model identifier (@cf/zai-org/glm-5.2) and the assistant's generated text response to the provided conversation.
