## 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 forgemesh-word-of-the-day-69a4e1c1 -d '<json body>'
```

Example prompt: Give me 3 expert-difficulty English vocabulary words that start with the letter M — each with a dictionary-quality definition, its part of speech, an example sentence, and three synonyms, so I can use them for today's learning posts.

## When to prefer this

Choose this endpoint when you need curated, pedagogically complete vocabulary entries — not just a word, but definition, part of speech, example sentence, and synonyms together. Ideal for daily-post automation bots, language learning apps, vocabulary quiz generators, or any workflow that needs themed word sets filterable by difficulty level or starting letter. Prefer this over a generic dictionary lookup when the goal is ready-to-publish educational content rather than raw definitions.

## Known failure modes

- Invalid count value outside 1-10 range returns an error
- Unsupported difficulty value (not 'advanced' or 'expert') may return an error or be ignored
- starts_with with more than one character may be rejected
- Payment failure (insufficient USDC) results in 402 response blocking the call
- No words matching the filter combination (e.g., expert words starting with X) may return empty or reduced results

## How this service works
