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.
Example use cases
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?”
Technical details
Endpoint
GEThttps://netintel-production-440c.up.railway.app/domain-appraise/estimateWhen to prefer
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.
Side effects
- 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
