How this service works
x402-paid LLM APIs on a private GPU fleet (Qwen3.8-27B, VL 30B). USDC on Base, settle in seconds via a self-hosted facilitator. Unique: verifier-gated correctness on /premium/deep — wrong answers regenerated free. First call free, no wallet: POST /premium/first.
Output
A JSON object containing a 'text' field with the model's generated response, 'elapsed_s' with the inference time in seconds, and 'model_tier' indicating the tier used (e.g. 'premium'). Payment is settled on-chain via USDC on Base before the response is returned.
Example use cases
Agent reasoning with pay-per-call LLM
“I need you to think through this multi-step logic puzzle for me using the Argo Hub premium model — 'A farmer has 3 sons and 17 horses; how do they divide them so each gets a whole number?' Pay the per-call fee and give me the answer.”
Multimodal vision query on uploaded image
“Run this image description request through the Argo Hub VL 30B vision model: here's a product photo URL — tell me what's in it, what condition it looks like it's in, and whether it appears authentic. Use the premium tier and charge the USDC fee.”
Automated content drafting for agent pipeline
“Draft a two-paragraph executive summary of the following market research notes using the Argo Hub Qwen3-27B model — I want high quality output and I'm fine paying the one-cent fee per call: [paste notes here].”
Technical details
Endpoint
POSThttps://diomedes.tail1c6d58.ts.net/premium/llmWhen to prefer
Choose this endpoint when your agent needs high-quality LLM inference (Qwen3 8B–27B or VL 30B) and can pay per call in USDC via the x402 protocol without needing a subscription or API key. It is especially well-suited for autonomous agents operating on Base that need to settle AI compute costs programmatically and in real time. Prefer it over OpenAI or Anthropic APIs when you want crypto-native payment rails, private GPU hosting, or the verifier-gated correctness guarantee available on the /premium/deep variant.
Side effects
- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Invalid or missing required input fields (description, mimeType, input.method) — returns 400 Bad Request
- Model generates an incorrect answer on /premium/deep — endpoint regenerates for free per verifier-gated correctness guarantee
- GPU fleet unavailable or overloaded — possible timeout or 503 Service Unavailable
- Malformed body or unsupported bodyType — returns 400 with schema validation error
- Facilitator settlement failure on Base — payment not confirmed, request rejected
