## 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-acronym-generator-e37e7d7b -d '<json body>'
```

Example prompt: Can you generate a creative acronym expansion for the phrase 'FAST' — like each letter stands for something meaningful about speed and technology?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.001 USDC) on-demand acronym generation without signup, especially in agentic pipelines that already use x402 crypto micropayments. Prefer this over LLM prompting when you want a dedicated, reproducible acronym tool rather than an ad-hoc generation.

## Known failure modes

- Empty or missing phrase returns validation error
- Phrase exceeding 500 characters is rejected
- Ambiguous short inputs may produce generic or low-quality expansions
- Non-Latin characters may not be handled gracefully
- Service may return 402 if payment is not provided upfront
