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'), and token usage breakdown (prompt tokens, completion tokens, total tokens), plus a unique completion ID.
Example use cases
One-off agent reasoning task
“I need a quick reasoning response from the Kimi-K2.6 model — ask it: 'What are three key risks in a DeFi lending protocol?' with up to 800 tokens at temperature 0.5, and pay per call so I don't need a subscription.”
Tool-calling agentic pipeline step
“Run a single chat completion with Kimi-K2.6 through Telnyx x402 — pass in my tool definitions for a weather API and a calendar API, then send the user message 'Schedule a meeting for tomorrow if it's not raining in New York', with max 1024 tokens.”
Crypto-native LLM API for startup prototype
“My app doesn't have an OpenAI key yet — can you send a test prompt 'Hello, what can you do?' to the Kimi-K2.6 model via Telnyx's pay-per-request x402 endpoint with temperature 1.0 and 200 max tokens, billing in USDC?”
Technical details
Endpoint
POSThttps://x402.telnyx.com/v1/chat/completions/_t/mid?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-request LLM inference with no subscription or API key commitment, paying in USDC via the x402 protocol. Ideal for autonomous agents, crypto-native apps, or prototypes that need OpenAI-compatible chat completions without account setup. Prefer this over standard OpenAI or Anthropic APIs when you want stablecoin micropayments and the Kimi-K2.6 model's reasoning capabilities specifically.
Side effects
- Payment failure: insufficient USDC balance or x402 payment header missing/invalid returns 402 Payment Required
- Model overload: high-traffic periods may return 503 or timeout
- Message too long: content exceeding 12,000 characters per message is rejected
- Token limit exceeded: max_tokens above 1024 is rejected by schema validation
- Tool array overflow: more than 16 tools in the tools array causes a validation error
- Message array overflow: more than 32 messages causes a validation error
