## 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 foundry-quote-api-97d6490a -d '<json body>'
```

Example prompt: Give me a public-domain quote about perseverance from a famous historical figure.

## When to prefer this

Choose this endpoint when you need a short, verified public-domain quote attributed to a well-known historical figure, especially when topic relevance matters. Prefer it over general LLM quote generation when citation accuracy and public-domain status are important, or when you want a lightweight, cheap ($0.001 USDC) single-call lookup rather than an LLM inference call.

## Known failure modes

- Topic word yields no matching quote — may return empty or fallback response
- Input string too long (over 8000 chars) — request rejected
- Network timeout from Render.com cold start — retry needed
- Payment not processed correctly — 402 response before content is returned

## How this service works

Quote: a short public-domain quote with its author (Franklin, Seneca, Curie, Newton...). Input: a topic word or 'any'.

## Output

A JSON object containing the quote text, the author's name (e.g. Franklin, Seneca, Curie, Newton), and a public_domain boolean confirming the quote is free to use.
