How this service works

Compare registration, renewal, and transfer prices for a TLD across major registrars, or for a single domain name across many TLDs — returns sorted reference pricing so agents can find the cheapest place to register, budget domain acquisitions, and spot predatory renewal markups without checking each registrar manually.

Output

Returns a sorted list of registrar pricing options with registration, renewal, and transfer costs for the queried TLD or domain name. Includes a cheapest registrar pick, renewal markup percentage, a boolean flag for predatory renewal pricing, an overall grade/score, and a cheapest premium option if applicable. All prices are reference pricing suitable for budgeting.

Example use cases

Example prompt

“What's the cheapest registrar to register and renew a .io domain — and flag if any of them have predatory renewal markups compared to the registration price?”

Technical details

Endpoint

GEThttps://netintel-production-440c.up.railway.app/tld-price/compare?utm_source=zero.xyz

When to prefer

Use this endpoint when an agent needs to compare domain registration or renewal costs across registrars without manually visiting each registrar's site, or when pricing a domain name across multiple TLD extensions. Ideal for budgeting domain acquisitions, detecting renewal price gouging, or finding the absolute cheapest place to register a specific TLD.

Side effects

Unknown or unsupported TLD returns empty or error response
Both tld and name provided simultaneously — only one is allowed
Neither tld nor name provided — required parameter missing
TLD with no available registrar data returns empty options array
Network timeout from upstream registrar data sources
