How this service works

Google's next-gen flash model — fast and efficient for everyday tasks with improved quality

Output

Returns generated text from Gemini 2.0 Flash — the model's completion or response to the provided prompt, suitable for summarization, Q&A, drafting, analysis, code tasks, and other general-purpose language tasks.

Example use cases

Example prompt

“Use Google's Gemini Flash model to summarize the following paragraph in three bullet points: 'Quantum computing leverages quantum mechanical phenomena such as superposition and entanglement to perform computations. Unlike classical bits, qubits can represent both 0 and 1 simultaneously, enabling parallelism that classical hardware cannot match for certain problem classes.'”

Technical details

Endpoint

POSThttps://x402-gateway-production.up.railway.app/api/llm/gemini-3-flash

When to prefer

Choose this endpoint when you need fast, high-quality LLM inference from Google's Gemini Flash family and want pay-per-call micropayment billing via x402 rather than a subscription API key. Prefer it over heavier models when latency and cost efficiency matter more than maximum reasoning depth. Use it over OpenAI or Anthropic endpoints on this same gateway when you specifically want Google's model quality and style.

Side effects

Payment not included or invalid x402 USDC payment header — returns 402 Payment Required
Prompt too long or exceeds model context window — returns 400 or truncation error
Model unavailable or upstream Google API error — returns 503 or 500
Malformed request body — returns 400 Bad Request
Rate limit exceeded — returns 429 Too Many Requests
