## 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 rafid-business-validation-plan-book-based-business-idea-validator-16bea855 -d '<json body>'
```

Example prompt: Can you validate my business idea? The idea is an online marketplace for handmade Omani crafts, the problem is that local artisans have no digital reach, my solution is a commission-based e-commerce platform, my target customers are tourists and diaspora shoppers, and my prospects are ['Ahmed Al-Balushi Pottery', 'Muscat Weavers Co-op']. Give me the validation in English.

## When to prefer this

Choose this endpoint when you need structured, book-grounded business validation for a startup or small business idea — especially for ventures in the Omani or Gulf Arab market. It is particularly suited for agents assisting entrepreneurs who need a framework-based (not just AI-generated) assessment anchored to a published business planning resource. Prefer this over generic LLM prompting when you need a citable, structured output tied to a real publication, or when the user needs Arabic-language business guidance.

## Known failure modes

- Missing required fields (idea, problem, customer, solution, or prospects) returns a validation error
- Prospects array is empty or exceeds 100 items — schema violation
- Text fields exceeding 2000 characters are rejected
- Invalid language enum value (must be 'ar' or 'en') causes request failure
- Payment not provided or insufficient USDC causes 402 Payment Required response
- Vague or very short input fields may produce low-quality or generic validation output

## How this service works

Rafid Agent API provides structured intelligence and paid APIs for AI agents across property, company and risk, supplier, finance, document, website, automotive, logistics, recruitment, trading, voice, video and business-planning workflows.

## Output

A JSON object containing a validation result tied to a specific book chapter (sourceChapter: 'book'), the language of the response, and a frameworkSource object with the title, edition, and publisher of the referenced business-planning book (e.g. 'How to Start Your Small Business in Oman', 2026 edition, Creative Techno). The chapter content provides structured, book-grounded business guidance relevant to the submitted idea.
