## 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 domain-name-value-estimator-57a723d5
```

Example prompt: Can you give me a quick value estimate for the domain name 'sparkly.io' — I want to know its value tier and quality score before I decide whether to buy it?

## When to prefer this

Use this endpoint when you need a fast, free-form domain quality estimate without paying for a commercial appraisal service like Estibot or GoDaddy Appraisals. Ideal for triaging large domain portfolios, screening acquisition candidates, or getting a transparent breakdown of what makes a domain valuable. Not suitable when you need a legally defensible market valuation or comparables-based pricing.

## Known failure modes

- Missing 'domain' query parameter returns a 400 or validation error
- Invalid or malformed domain string may return an error or a very low score
- Uncommon TLDs may not have premium pricing data, reducing score accuracy
- Payment failure or missing x402 header returns 402 Payment Required
- Network or server unavailability on Railway returns 5xx

## How this service works

Estimate the market value tier of a domain name using transparent heuristics — length, TLD premium, dictionary-word presence, pronounceability, keyword value, and numeric/hyphen penalties — returns a value tier and 0-100 quality score so agents can triage domain portfolios and prioritize acquisitions without a paid appraisal service.

## Output

Returns a structured object including the domain name, TLD, extracted name, letter grade, numeric value score (0-100), value tier label (e.g. 'premium', 'standard'), an array of scoring factors with explanations, an array of findings, and a characteristics object summarizing key domain attributes.
