How this service works
12 pay-per-call HTTP APIs settled in USDC on Base via x402 v2. No API keys, no accounts, no signup — $0.0005–$0.0020 per call. Includes a locally hosted 27B LLM endpoint.
Output
A JSON object containing the model identifier (e.g. 'qwen3.8:27b') and the generated text content string from the LLM, returned synchronously after inference completes.
Example use cases
Anonymous LLM inference for agent reasoning
“I need you to reason through this multi-step problem using SableForge's 27B model — no accounts, just pay per call. System prompt: 'You are a logical reasoning assistant.' User: 'If all bloops are razzles and all razzles are lazzles, are all bloops lazzles? Explain step by step.'”
Crypto-native chatbot backend
“Use the SableForge 27B LLM to generate a customer support reply. System: 'You are a friendly e-commerce support agent.' User: 'My order hasn't arrived in 10 days, what should I do?'”
Private document summarization via local LLM
“Pass this text to SableForge's locally hosted Qwen 27B model and ask it to summarize in three bullet points. User message: 'The quarterly report shows revenue up 18% YoY driven by enterprise subscriptions, while operating expenses grew only 6%, resulting in improved EBITDA margins of 24%.'”
Technical details
Endpoint
POSThttps://sableforge.servehttp.com/api/llm?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call LLM inference with no API key registration, no monthly subscription, and anonymous access settled in USDC on Base. It is especially well-suited for AI agents that hold crypto wallets and need to invoke LLM reasoning on demand. Prefer it over OpenAI or Anthropic APIs when avoiding account creation is a hard requirement, or when operating in a fully on-chain / x402 payment context. The 27B parameter size (Qwen3) provides strong general reasoning at a fraction of frontier model cost.
Side effects
- Payment not settled — 402 response returned if USDC payment via x402 v2 is not included or fails
- Malformed messages array — missing role or content fields cause a 400 error
- Model overload — locally hosted hardware may introduce latency spikes or 503 under high concurrency
- Empty or null content — if messages array is empty, response may be undefined or error
- Network unavailability — servehttp.com dynamic DNS may have uptime variability
