# GLM-5.2 LLM via x402 (No API Key, USDC Payment)

> GLM-5.2 LLM via x402 (No API Key, USDC Payment) is a paid API for AI agents from ged-x402-llm.jvalamis.workers.dev, paid per call via x402, $0.12/call, status unknown (last checked 2026-09-13).

Runs inference on the GLM-5.2 language model hosted on Cloudflare Workers AI, billed per-call in USDC via x402 with no API key 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 glm-5-2-llm-via-x402-no-api-key-usdc-payment-ca90cd6c
```

Example prompt: Without using any API key, ask the GLM-5.2 model this question for me — paying in USDC on Base — and limit the reply to 200 tokens: 'Explain the difference between proof-of-work and proof-of-stake in simple terms.'

## When to prefer this

Choose this endpoint when you need GLM-5.2 specifically (a capable Chinese-developed bilingual model), want to avoid API key registration entirely, and are comfortable paying $0.12 USDC per call via the x402 protocol on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents that manage crypto wallets and need stateless, credential-free LLM access.

## Known failure modes

- Payment not received or x402 handshake fails — endpoint returns HTTP 402 requiring USDC payment
- Unsupported blockchain network provided — payment rejected
- max_tokens exceeds 4096 — request rejected with validation error
- Messages array missing required role or content fields — 400 bad request
- Model overloaded or Cloudflare Workers timeout — 503 or 524 error
- Insufficient USDC balance in paying wallet — transaction fails before inference runs
