## 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 fastapi-online-poem-generator-a4e114fc -d '<json body>'
```

Example prompt: Can you write me a poem about the changing seasons in a melancholy, introspective style?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.001 USDC per call), no-signup poem generation with style control. It is ideal for agents that need to generate creative poetry on demand without API key friction, especially in crypto-native or x402-payment-enabled workflows. Prefer it over large-platform LLM calls when cost-per-call minimization and pay-as-you-go crypto billing are priorities.

## Known failure modes

- Missing required 'topic' or 'style' fields returns a validation error
- Topic or style string exceeding maxLength limits (500 and 100 chars respectively) may be rejected
- Payment failure or insufficient USDC balance results in 402 Payment Required
- Self-hosted model downtime may result in 503 Service Unavailable
- Extremely vague topics may yield generic or low-quality output
