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), and a completion ID.

Example use cases

Crypto-paid AI assistant for agent pipelines

“I need to run a quick GLM-5.1 chat completion through Telnyx's x402 gateway — send the message 'Summarize the following text in one sentence: [text]' as a user message, limit it to 512 tokens, and pay per-request with USDC.”

Tool-calling workflow with GLM model

“Call the Telnyx GLM-5.1-FP8 model via x402 with my tool definitions and these messages: system 'You are a function-calling assistant', user 'What's the weather in Berlin?' — use temperature 0 and max 1024 tokens so it picks the right tool.”

Low-cost per-query LLM for a chatbot

“Send a multi-turn conversation to the Telnyx x402 GLM model — the assistant should have a 'You are a customer support bot' system prompt, then a user message 'How do I reset my password?', keeping temperature at 1 and max tokens at 200.”

When to prefer

Choose this endpoint when you need pay-as-you-go LLM inference with no subscription, settling per-call in USDC via the x402 micropayment protocol. It is ideal for agents or pipelines that need the GLM-5.1-FP8 model specifically, or for use cases where traditional API key billing is impractical and crypto-native payment rails are preferred. It also suits sporadic or bursty workloads where committing to a monthly plan is undesirable.

Side effects

Insufficient USDC balance or failed x402 payment — request rejected with 402 Payment Required
Message array exceeds 32 items or content exceeds 12,000 characters — validation error
max_tokens exceeds 2048 or is below 1 — schema validation failure
Temperature out of range [0, 2] — rejected by input validation
Model identifier mismatch — only 'zai-org/GLM-5.1-FP8' is accepted on this route
Tool array exceeds 16 items — schema validation failure
Network timeout or inference backend unavailable — 5xx error
