# GEDX402 Qwen2.5-Coder-32B-Instruct LLM

> GEDX402 Qwen2.5-Coder-32B-Instruct LLM is a paid API for AI agents from llm.gedx402.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Runs inference on Alibaba's Qwen2.5-Coder-32B-Instruct coding model via Cloudflare Workers AI, billed per-call in USDC over 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 gedx402-qwen2-5-coder-32b-instruct-llm-c31aaf1b
```

Example prompt: Ask the Qwen2.5-Coder-32B model to write a Python function that sorts a list of dictionaries by a given key, using a system prompt that says 'You are an expert Python developer' and limiting the reply to 512 tokens.

## When to prefer this

Choose this endpoint when you need a powerful 32-billion-parameter coding-specialized LLM (Qwen2.5-Coder) without signing up for API keys, and you can pay per-call in USDC on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents that need on-demand code generation or debugging with crypto-native payment flows.

## Known failure modes

- Payment not received or insufficient USDC balance — returns HTTP 402 with payment instructions
- Messages array malformed or missing required role/content fields — returns 400 validation error
- max_tokens exceeds 4096 — request rejected with schema validation error
- Network timeout on Cloudflare Workers AI backend — returns 5xx error
- Unsupported blockchain network for payment — payment step fails before inference

## 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/qwen/qwen2.5-coder-32b-instruct' and a 'response' string holding the assistant's generated text, typically code or a code-related explanation.
