Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-cloud-ai-inference-gemini-text-generation-endpoint-c07f4658 -d '<json body>'
```

Example prompt: Using the x402 Cloud Gemini inference endpoint, generate a response to this prompt: 'Summarize the key risks of algorithmic trading in 3 bullet points' — limit the output to 512 tokens.

## When to prefer this

Prefer this endpoint when your agent or backend needs Gemini text generation without a traditional API subscription, wants to pay per call in USDC via x402 protocol, is operating autonomously without pre-provisioned API keys, or needs the lowest-cost x402-compatible AI inference available. Ideal for autonomous agents, RAG pipelines, creative automation, and trading bots that need on-demand LLM access with crypto payment rails.

## Known failure modes

- 402 Payment Required if USDC payment header is missing or insufficient
- Invalid prompt length if prompt exceeds 32000 characters or is empty
- Model error if contents array is malformed or incompatible with Gemini schema
- Rate limiting or quota exhaustion on the underlying Gemini model
- Timeout for very large maxOutputTokens values near the 8192 limit
- Malformed generationConfig causing generation to fail silently
