How this service works
Chat completions via Telnyx Inference (moonshotai/Kimi-K2.5). OpenAI-compatible. $0.016673 USDC per call. (upto metered — large context)
Output
Returns an OpenAI-compatible chat completion object containing the assistant's generated message, finish reason, token usage counts, and any tool call invocations if tools were provided. The model field in the response confirms moonshotai/Kimi-K2.5 was used.
Example use cases
Long-context document analysis agent
“I have a 150,000-character legal document I need analyzed — use Kimi-K2.5 on Telnyx to extract all the indemnification clauses and summarize them. Set max_tokens to 2048 and temperature to 0.2 for a precise response.”
Agentic tool-calling workflow
“Build a multi-step research loop using Kimi-K2.5 on Telnyx Inference — give it these three tool definitions for web search, calculator, and calendar lookup, then ask it: 'What are the top AI funding rounds from last quarter and what was the total amount?' Let it call tools as needed.”
Creative long-form content generation
“Use the Kimi-K2.5 model via Telnyx to write a detailed 2,000-word product requirements document for a mobile expense tracking app, starting from this one-line brief: 'An app that automatically categorizes receipts and tracks budgets.' Set temperature to 0.9 and max_tokens to 4096.”

Endpoint
POSThttps://x402.telnyx.com/v1/chat/completions/_t/kimi-k2.5/upto?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need Moonshot AI's Kimi-K2.5 model specifically — known for strong long-context reasoning — and want a pay-per-call model with no subscription or API key management via Telnyx's x402 micropayment system. Prefer it over cheaper Telnyx sibling models (DeepSeek, Gemma) when the task requires extended context windows or Kimi-K2.5's particular reasoning style. The 'upto' (metered/large context) route is best for prompts that may grow large, as opposed to a fixed small-context route.
Side effects
- Payment failure (x402): insufficient USDC balance or wallet not configured, returns 402 Payment Required
- Content too long: messages array exceeds 200,000 chars per message or 32-message limit, returns 400
- Invalid model value: any model string other than 'moonshotai/Kimi-K2.5' will be rejected
- max_tokens out of range: values above 8192 or below 1 return validation error
- Temperature out of range: values outside 0–2 return 400 Bad Request
- Tools array exceeds 16 items: returns validation error
- Rate limiting or upstream inference timeout from Telnyx backend: 503 or 504
