How this service works

Chat completions via Telnyx Inference (google/gemma-4-26B-A4B-it). OpenAI-compatible. $0.003139 USDC per call.

Output

Returns an OpenAI-compatible chat.completion JSON object with the assistant's generated message, finish reason (e.g. 'stop'), and token usage breakdown (prompt tokens, completion tokens, total tokens). The model field is fixed to google/gemma-4-26B-A4B-it.

Example use cases

One-off LLM answer without subscription

“I just need a single smart response from a powerful AI model — use Gemma 4 26B to answer 'What are the main trade-offs between microservices and monoliths?' in about 300 tokens, paying per request so I don't have to sign up for anything.”

Agentic tool-using chatbot step

“My agent needs to call Gemma 4 26B with a system prompt saying 'You are a helpful coding assistant' and a user message 'Write a Python function to parse a CSV file', with tool definitions for file operations, using a temperature of 0.2 and max 800 tokens.”

Cost-controlled content drafting

“Draft a short product description for a noise-cancelling headphone using Gemma 4 26B — keep it under 200 tokens, temperature 0.8, and bill it per call in USDC so I only pay for what I use.”

When to prefer

Choose this endpoint when you need pay-per-request LLM inference with Google Gemma 4 26B without committing to a subscription or managing API keys — ideal for low-volume, sporadic, or agent-driven workloads where USDC micropayments via x402 are acceptable. Prefer it over OpenAI or Anthropic endpoints when you specifically want the Gemma 4 26B model or need Telnyx's infrastructure with per-call billing.
