x402
Argo Hub — Deep LLM Inference (x402-paid) is a paid API for AI agents from diomedes.tail1c6d58.ts.net, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-18).
Runs a deep LLM inference call on a private GPU fleet (Qwen3-27B-class) with verifier-gated correctness guarantees, paid per-call in USDC via x402.

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
Returns a JSON object containing a 'text' field with the model's generated response and a 'model_tier' field set to 'deep', indicating which inference tier handled the request. If the verifier deems the answer incorrect, the response is regenerated at no additional cost.
Example use cases
Per-call AI reasoning for agent pipeline
“I need to run a complex multi-step reasoning query through a pay-per-call LLM without signing up for a subscription — use the Argo Hub deep model and pay the $0.05 USDC fee automatically. The question is: 'Given the following financial data, what is the most likely cause of the Q3 revenue dip?'”
Correctness-guaranteed factual Q&A
“Ask the Argo deep inference endpoint whether the Pythagorean theorem applies in non-Euclidean geometry, and make sure we get a verified correct answer — I want the free regeneration guarantee if it gets it wrong.”
Vision-language analysis on private GPU
“Send this product image description to the Argo Hub deep model and ask it to generate a detailed marketing copy paragraph — I want to use the verifier-gated tier so we only pay if the output is actually good.”
Technical details
Endpoint
POSThttps://diomedes.tail1c6d58.ts.net/premium/deepWhen to prefer
Choose this endpoint when you need high-quality, deep reasoning LLM output with a correctness guarantee, are comfortable with per-call USDC micropayments via x402 on Base, and want to avoid subscription-based APIs. Particularly valuable for agent pipelines that require reliable, verifiable answers and want automatic free regeneration on wrong outputs. Prefer over standard hosted APIs when cost-per-call economics matter and you want a self-hosted, private GPU backend rather than shared cloud inference.
Side effects
- Payment not settled — x402 USDC transaction fails or wallet has insufficient funds, resulting in a 402 response and no inference
- Invalid input schema — missing required fields ('description', 'mimeType', 'input.method') returns a 400-class error
- Model timeout — long-running deep inference exceeds GPU time limits and returns a 504 or equivalent error
- Verifier loop — rare edge case where regenerated answers repeatedly fail correctness checks, potentially stalling the response
- Network unreachable — private Tailscale domain (ts.net) may be inaccessible outside the operator's network
