GPU Forge LLM Generate
x402
GPU Forge LLM Generate is a paid API for AI agents from forge.parabellum.tech, paid per call via x402, $0.05/call, status down (last checked 2026-10-13).
Generates text from a prompt using a GPU-accelerated LLM (default: llama3.1:8b), billed per call in USDC with no account or API key required.

How this service works
Machine-payable GPU compute. Pay per call in USDC on Base or Polygon, no accounts, no API keys.
Output
Returns a JSON object containing the model name used, the generated text response string, and an eval_count integer representing the number of tokens evaluated. The response field holds the raw LLM completion text.
Example use cases
Autonomous agent LLM reasoning step
“I need you to call a pay-per-use LLM endpoint using llama3.1:8b to reason through this logic puzzle: 'If all bloops are razzles and all razzles are lazzles, are all bloops lazzles?' — limit the response to 300 tokens and pay in USDC.”
Crypto-native app text summarization
“Summarize this paragraph using the llama3.1:8b model on GPU Forge with no API key needed — just pay per call in USDC: 'Decentralized finance allows users to access financial products without intermediaries, leveraging smart contracts on public blockchains.' Keep it under 100 tokens.”
No-signup LLM prototype testing
“I'm prototyping an app and want to test LLM output quality without creating any accounts — can you send a prompt to GPU Forge asking llama3.1:8b to write a haiku about the ocean, with max 50 tokens, paying in USDC on Polygon?”
Technical details
Endpoint
POSThttps://forge.parabellum.tech/v1/jobs/llm.generate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need anonymous, pay-per-call LLM text generation without accounts or API keys, especially in machine-to-machine or agent contexts where USDC payments on Base or Polygon are already available. Ideal for crypto-native apps, autonomous agents needing one-off inference, or prototyping where signup friction is unacceptable.
Side effects
- Payment not received or insufficient USDC — returns HTTP 402 Payment Required
- Prompt field missing — returns validation error
- max_tokens exceeds 2048 cap — capped silently or returns error
- Requested model not available on the node — returns model load error
- Network timeout during GPU inference for long prompts
