How this service works

LLM inference API: OpenAI-compatible chat completions for 136 AI models (Claude, GPT, Gemini, Grok, DeepSeek, Qwen, Kimi, GLM), paid per call in USDC on Base with x402. No account, no API key, automatic refund if the model fails.

Output

Returns a standard OpenAI-format chat.completion JSON object containing the assistant's message content, finish reason (e.g. 'stop'), prompt/completion/total token counts, model identifier ('moonshot/kimi-k3'), and a unique completion ID. When streaming is enabled, responses arrive as server-sent events. If the model fails, an automatic refund is issued.

Example use cases

Crypto-native agent calling LLM

“I'm building an autonomous agent that needs to call an LLM without managing API keys or subscriptions — use Kimi K3 to answer the user's question and pay the $0.0023 per-call fee in USDC automatically.”

Rapid prototyping without signup

“I want to test Kimi K3's reasoning on this math problem without creating any account — just send it my message and deduct the USDC cost from my wallet.”

Streaming chat response generation

“Generate a detailed step-by-step cooking recipe using Kimi K3, stream the response as it comes in, and limit the output to 1000 tokens — bill it per-call in USDC.”

When to prefer

Choose this endpoint when you need Kimi K3 (Moonshot) specifically, want to pay per-call in USDC without an API key or account, need an OpenAI-compatible interface for easy drop-in use, or are building crypto-native agents that manage their own payments. Prefer alternatives if you need a different model family, want traditional API-key billing, or require SLA guarantees beyond automatic refunds.
