How this service works

Pay USDC per request for Telnyx Inference and Audio (text-to-speech, speech-to-text) through x402.

Output

Returns an OpenAI-compatible chat completion JSON object containing the assistant's reply message, finish reason (e.g. 'stop'), token usage breakdown (prompt, completion, total tokens), a unique completion ID, and the object type 'chat.completion'.

Example use cases

Long document summarization with Kimi

“I have a 40,000-word legal contract I need summarized into key clauses and risks — can you send it to the Kimi-K2.6-long model on Telnyx and get back a structured summary? Use temperature 0.3 and up to 2000 tokens.”

Multi-turn coding assistant session

“Start a conversation with the Kimi long-context model via Telnyx where the system says 'You are an expert Python engineer' and I ask: 'Refactor this 800-line Python module for readability and add type hints.' Use temperature 0.5 and limit the reply to 2048 tokens.”

Research Q&A over large corpus

“Send the entire text of this 30,000-word academic paper to the Kimi-K2.6-long model through Telnyx and ask it: 'What are the three most significant findings and their methodological limitations?' Temperature 0.2, max 1500 tokens.”

When to prefer

Choose this endpoint when you need a long-context LLM (up to 200,000 characters per message, 64-message history) and want pay-per-request billing in USDC with no subscription or API key setup. It is especially well-suited for agents that need to process large documents, long codebases, or extended conversation histories using Moonshot AI's Kimi-K2.6-long model. Prefer this over standard OpenAI-compatible endpoints when you specifically want crypto-native microtransaction billing via x402 and the unique long-context strengths of Kimi.

Side effects

Payment failure: insufficient USDC balance or x402 payment rejected — request blocked before reaching model
Context too long: messages exceeding 200,000 characters per message or more than 64 messages returns a validation error
max_tokens out of range: values below 1 or above 2048 return a schema validation error
Temperature out of range: values outside 0–2 rejected
Model mismatch: specifying any model other than moonshotai/Kimi-K2.6-long returns an error since model is fixed on this route
Rate limiting or gateway timeout for very large payloads
Network or upstream Telnyx inference service unavailability
