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 JSON object with a choices array containing the assistant's generated message, finish reason, token usage breakdown (prompt, completion, total tokens), and a unique completion ID.

Example use cases

Autonomous agent task reasoning

“I want you to think through this multi-step customer support problem using the GLM-5.3-Flash model on Telnyx: system prompt 'You are a customer support specialist', user message 'My order #4821 hasn't arrived after 3 weeks — what are my options?', temperature 0.5, max 1024 tokens.”

Tool-calling workflow orchestration

“Call the Telnyx GLM-5.3-Flash endpoint with my tool definitions for calendar_lookup and email_send, system 'You are a scheduling assistant', user 'Schedule a meeting with John on Friday at 3pm and send him a confirmation', and use temperature 0.3 with 512 max tokens.”

Content drafting with crypto micropayment

“Use the Telnyx x402 GLM-5.3-Flash model to draft a short product description — system: 'You are a copywriter', user: 'Write a 3-sentence description for a noise-cancelling bluetooth headset aimed at remote workers' — temperature 0.9, max tokens 512, and pay with USDC per call.”

When to prefer

Choose this endpoint when you need a fast, OpenAI-compatible chat completion using the GLM-5.3-Flash model and want to pay per-request in USDC without a subscription or API key setup. Ideal for autonomous agents that need on-demand LLM inference with crypto-native micropayments via x402, particularly when avoiding centralized billing or when running sporadic, pay-as-you-go inference workloads.

Side effects

Payment failure if USDC balance is insufficient or x402 payment header is missing/malformed
Model or route unavailable (5xx errors from Telnyx inference backend)
Message content exceeds 32,000 character limit per message
Too many messages in the conversation (exceeds 32-message limit)
max_tokens out of range (must be 512–2048)
Temperature out of range (must be 0–2)
Too many tool definitions (exceeds 16-tool limit)
