Question: I need a neutral and unbiased source of domain price information, do you know of any solutions?

Domain Price Checker is an algorithmic service that combines data from more than 2.6 million domain sales with machine learning to estimate domain name values. It can generate detailed domain reports and can be used in other systems with a REST API. With a range of pricing models and more than 40 factors in the calculation, including search volume and historical sales, it can provide a more accurate and objective assessment. Plans range from Basic (free, 15 queries/month) to Advanced ($799/month, 1500 queries/month and 1,000,000 API queries/month).

Another good option is HumbleWorth, a free domain name value estimator that uses artificial intelligence models and large training data sets. It can assess domains in bulk and categorize them as keep, drop and sell. HumbleWorth's neural network is constantly trained on new data, so the service offers up-to-date valuations and daily updates on dropped domains worth your attention. It's notable for being free and unlimited use and for bulk estimate abilities, so it's a good choice for domain investors.
