> GEDX402 Llama 3.3 70B Instruct (x402 Pay-Per-Call) is a paid API for AI agents from ged-x402-llm.jvalamis.workers.dev, paid per call via x402, $0.06/call, status unknown (last checked 2026-09-13).

Runs inference on Meta's Llama 3.3 70B Instruct FP8 Fast model via Cloudflare Workers AI, billed per-call in USDC with no API key required

## 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-llama-3-3-70b-instruct-x402-pay-per-call-1c6478f4
```

Example prompt: Ask Llama 3.3 70B: given the system prompt 'You are a helpful coding assistant', reply to the user message 'Write a Python function that reverses a linked list' and limit the response to 512 tokens — pay with USDC on Base.

## When to prefer this

Choose this endpoint when you need pay-per-call LLM inference without API key registration, want to pay in USDC via x402 on a supported chain (Base, Polygon, Arbitrum, World, Solana), and specifically want the Llama 3.3 70B Instruct FP8 Fast variant for high-quality instruction-following at a cost of $0.06 per call.

## Known failure modes

- Payment not received or insufficient USDC balance — returns HTTP 402 with payment details
- Invalid message role (not system/user/assistant) — returns validation error
- max_tokens exceeds 4096 — returns schema validation error
- Empty messages array — may return empty or error response
- Network timeout if model inference takes too long under load
- Unsupported payment network — only Base, Polygon, Arbitrum, World, Solana accepted

## 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/meta/llama-3.3-70b-instruct-fp8-fast') and a 'response' string with the assistant's generated text reply to the provided conversation.
