Common questions.

Everything people ask before they descend.

Do I need a credit card to use the free tier?
No. Free access requires no account and no payment details. Just visit map.pyramason.com and start exploring.
What payment methods are accepted?
All major credit and debit cards via Stripe: Visa, Mastercard, American Express. Payment is secure and handled entirely by Stripe.
Can I cancel anytime?
Yes, cancel anytime with no fees. Your Pro access continues until the end of your billing period. Manage your subscription through your account or contact support@pyramason.com.
What are Antiquity and Empires?
Two free layers. Antiquity strips the modern world off the map, roads, borders and present-day labels, and raises 58 great cities of the ancient world under their own names. Empires draws 16 civilisations at their greatest extent, each with an engraved seal at its capital. Both are included on the free tier.
What are Documented Alignments and Gnomon Shadow?
Two free tools added in September 2026. Documented Alignments lists what archaeoastronomers have actually measured at 17 famous sites: 48 sourced entries, each tagged documented, contested, claimed or rejected, recomputed by the map for the site latitude and building epoch, with an Azimuth Identifier for testing your own measurements. Gnomon Shadow draws the shadow-tip track of a vertical rod for any place, date and epoch at true scale. Both are included on the free tier.
How do I connect my AI to the map?
Paste map.pyramason.com/mcp into Claude, ChatGPT or any AI that speaks MCP. Six tools, with null models and p-values on the geometry engines. It works free for everyone at 300 calls a day; Pro researchers get a personal key with 20,000 calls a day.
Are there bulk or institutional licences?
Yes. For universities, research institutions or organisations needing multiple seats or bulk dataset access, contact us at contact@pyramason.com.
