How this service works
Paid d402 capability alias for llm.inference@1. Workers can wrap local Ollama/LM Studio/llama.cpp/vLLM or consumer/free-tier OpenAI-compatible APIs and sell completions through d402 without exposing provider keys.
Output
Returns a taskId and status, plus a result object containing the generated text completion, model name, provider name, prompt and response hashes for auditability, token usage stats, and optionally raw choices array. Also includes settlement and validation receipt metadata from the d402 payment network.
Example use cases
Example prompt
“Using the d402 LLM gateway with the ollama provider, send the prompt 'Explain quantum entanglement in simple terms' to llama3 with a temperature of 0.7 and max 300 tokens.”
Technical details
Endpoint
POSThttps://gateway.d402.xyz/v1/llm/inferenceWhen to prefer
Choose this endpoint when you need LLM text completions without managing API keys or subscriptions, want to pay per-call in USDC via the d402 micropayment network, need access to local or open-source model providers (Ollama, llama.cpp, vLLM), or want auditable inference with prompt/response hashes for verification. Prefer over direct OpenAI/Anthropic APIs when decentralization, worker-owned compute, or crypto-native payment settlement is required.
Side effects
- No workers available for requested provider/model — returns status=error with error message
- Payment not settled or insufficient USDC — request rejected before inference runs
- Timeout exceeded (max 45000ms) — returns status=error
- Model not allowed by seller profile — may return error or fall back to default model
- Provider credentials expired on worker side — worker returns error passed through as status=error
- Invalid messages format — request rejected with validation error
