How this service works
Pay-per-call chat completion on the nano tier. One request returns one assistant message, limited to 1000 input and 256 output tokens, at 0.006 USDC per call on Base. Payment settles after the response is produced. A client nonce header makes a retry free of a second charge.
Output
A single assistant message text in response to the provided prompt or conversation, generated by the selected model (auto, llama-3.1-8b, or kimi-k3), bounded by max_tokens (up to 256). Payment of 0.006 USDC is settled via x402 on Base after the response is produced.
Example use cases
Quick factual Q&A bot
“Use the nano chat model (auto tier) to answer this user question in one short paragraph: 'What are the main differences between TCP and UDP?'”
Lightweight content classifier
“Send this customer message to the kimi-k3 nano model and ask it to classify the sentiment as positive, negative, or neutral — limit the reply to 50 tokens: 'The shipping was fast but the product broke on day one.'”
Cheap multi-turn assistant
“Run a two-turn conversation through the nano chat endpoint using llama-3.1-8b: first message is 'You are a helpful cooking assistant', then the user says 'Suggest a 3-ingredient pasta sauce I can make in 10 minutes'. Keep the reply under 150 tokens.”
Technical details
Endpoint
POSThttps://pay.omnidev.tech/x402/chat-nano?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a very cheap, low-latency single-turn or short multi-turn LLM call (nano tier), pay per call with no subscription, and your input fits within 1000 tokens and output within 256 tokens. Ideal for agents that need occasional LLM inference without committing to a monthly API plan, or for high-volume pipelines where per-call cost control is critical.
Side effects
- Prompt or messages exceed 1000 input token limit — request rejected
- max_tokens exceeds 256 — validation error
- Payment failure or insufficient USDC balance — 402 Payment Required
- Invalid model enum value — 400 Bad Request
- Both prompt and messages absent — 400 Bad Request
- Network timeout before response is returned
