How this service works

Gambit GPU shop. Pay with L402 Lightning on /l402/* or x402 USDC on Base on /x402/*. Handwritten letter POST /x402/letter at $25.00 USDC. Funnel https://spark-2f53.tail8a7863.ts.net/gambit. Cheap probe GET|POST /x402/models at $0.01 USDC.

Output

Returns a JSON object containing the model name used and an assistant message object with role and content fields — the generated text reply from the LLM.

Example use cases

Crypto-native AI chatbot backend

“I'm building a chatbot that pays per inference in USDC — send this user message 'What are the best practices for Solidity smart contract security?' to the qwen3.6:35b-a3b model on Gambit with max 512 tokens.”

Automated code review via LLM

“Use the Gambit chat endpoint with model qwen3.6:35b-a3b to review this snippet: 'for i in range(len(arr)): print(arr[i])' — ask it to suggest a more Pythonic version, limit to 300 tokens.”

On-demand AI summarization for agent pipeline

“Have Gambit's GPU inference run a summarization: send the assistant role message 'Summarize the following article in three bullet points: [article text]' using qwen3.6:35b-a3b, max 400 tokens, and charge my x402 wallet the $0.02 fee.”

When to prefer

Choose this endpoint when you need GPU-accelerated LLM chat completions with per-call USDC micropayment billing via the x402 protocol on Base, especially when working with open-source models like Qwen hosted on a self-operated GPU shop. Prefer it over centralized API providers when you want crypto-native, pay-per-use inference without subscription accounts.

Side effects

Payment failure: x402 USDC payment on Base not authorized or insufficient balance — returns 402 Payment Required
Invalid model name: model string does not match a hosted model — likely 4xx or model-not-found error
Malformed messages array: missing required role or content fields — 400 Bad Request
Token limit exceeded or inference timeout on GPU — possible 5xx or timeout response
Network unreachability of the Tailscale host — connection refused or DNS failure
