FAQ

Common questions.

What happens when my trial calls run out?
The key stops working after 5 calls. Sign up for a paid plan to continue. Your key is reactivated when the plan goes live in Q3 2026.
Is my data stored or used to train anything?
Nothing is stored. Queries are not logged. Images uploaded for palette extraction are discarded the moment processing completes. Your colour research does not update or retrain the archive. GDPR compliant. UK registered.
What is the /mix endpoint?
Send two or more pigment names and a medium (oil, fresco, tempera, watercolour) and receive documented incompatibility warnings from historical trade manuals. Cennini (c.1390), Tingry (1830), Field (1835), Church (1890). If Cennini documented it in 1390, you will receive his exact words. For artistic and archival reference only — not engineering or safety-critical advice.
What is the Resonance Index?
Cross-archive colour connections indexed by perceptual distance. Every colour query returns resonance matches — where the same colour appears across other archives. Bledington Corn (Oxfordshire) resonates with Maturing Sun (Keats, To Autumn). Prussian Blue connects the Dutch Golden Age archive, the pigment chemistry archive, and three literary archives simultaneously.
How does MCP integration work?
The MCP server is live at colour-memory-api-production.up.railway.app/mcp. Add it to your Claude Desktop config or any MCP-compatible agent. All tools register automatically. No custom integration required.
When do paid plans launch?
Q3 2026. Join the waitlist above and the founding rate is locked permanently. You will be first in when the doors open.
