Last updated: 2026-10-11. This page explains what QuantX402 (quantx402.app, run by FDWA) collects and the terms for using the API.
What we log for API and page requests
For each request we store the path, method, HTTP status, a coarse client class (for example "AI crawler", "x402 client" or "browser") and, where it matches a known list, the bot or agent name. We do not store IP addresses or full user-agent strings. Site analytics use Vercel Web Analytics, which is cookie-free.
Payments
When an agent pays with x402, we store the amount, network, settlement transaction hash and the paying wallet address, all of which are already public on the blockchain. We never hold your private keys and we can't move funds from your wallet. Payments settle only for successful responses.
Free skill download
If you request the free Kronos skill, we store your email, your consent to updates, the time, which link or site sent you, and a salted hash of your IP to prevent abuse (never the IP itself). We don't sell or share it. To be removed, email quantx402@mail.grokbot.com or message @fdwa_ai on X.
Third parties
Hosting: Vercel. Database: Neon. Payment verification and settlement: Coinbase CDP facilitator. Ticker prices: CoinGecko (attributed on the page). Forecast inputs: public exchange candles (see Data sources).
