How this service works
Google's fastest and cheapest model — ideal for high-volume, low-latency tasks
Output
Returns a natural language completion or response generated by Google's Gemini Flash Lite model. Typically includes the generated text content, and may include token usage metadata. The response reflects the model's output for the given prompt at low latency.
Example use cases
Example prompt
“Use the Gemini Flash Lite model to summarize the following customer support ticket in one sentence, keeping it snappy and low-cost since we'll be doing thousands of these: 'Hi, I ordered a blue hoodie two weeks ago but received a red one and still haven't heard back from support.'”
Technical details
Endpoint
POSThttps://x402-gateway-production.up.railway.app/api/llm/gemini-3.1-flash-liteWhen to prefer
Choose this endpoint when you need fast, cost-effective LLM inference at high volume and low latency, and don't require frontier reasoning capability. Ideal for bulk classification, summarization, extraction, or simple generation tasks where cost per call matters. Prefer this over GPT-4-class or reasoning models when throughput and price are priorities. Use when your agent workflow involves many small LLM calls and you want to pay per-call via USDC micropayment without subscription overhead.
Side effects
- Insufficient USDC balance or x402 payment failure — returns 402 Payment Required
- Malformed prompt or missing required fields — returns 400 Bad Request
- Model quota exceeded or Google API unavailability — returns 503 or 500
- Overly long prompt exceeding context window — returns 400 or truncation error
- Network timeout on gateway — returns 504 Gateway Timeout
