## 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 glianaai-gpt-5-5-pro-text-generation-fb93fff3
```

Example prompt: Use GlianaAI's GPT-5.5-Pro endpoint to write me a concise, professional summary of the following project brief — pay per call with USDC, no account needed: 'We are building an AI-powered supply chain optimization tool for mid-size manufacturers.'

## When to prefer this

Choose this endpoint when you need GPT-5.5-Pro-level text generation without an OpenAI subscription or API key, and you want to pay per call in USDC via the x402 protocol. Ideal for autonomous AI agents that need powerful LLM reasoning on demand with crypto-native micropayments and no upfront account setup.

## Known failure modes

- Payment not received or insufficient USDC — HTTP 402 returned, generation not performed
- Invalid or missing input body — HTTP 400 with schema validation error
- Model temporarily unavailable — HTTP 503 or timeout
- Malformed request format — HTTP 422 if body type or method is incorrect
- Rate limit exceeded — HTTP 429 if too many concurrent calls
