Case — inside the system
Every price has a receipt.
A public record of what things actually cost — sourced, dated, tamper-evident.
23k+
citable pages, every fact sourced
4,400+
entities under the record
19
tools served to AI agents
SHA-256
chained, tamper-evident ledger
FrontDesk is built on institutional distrust of its own content. Writer agents compile products and prices from published sources; a second, adversarial agent exists only to refute them. Whatever survives meets the fidelity gate, which re-fetches every cited page and refuses to ship any number that isn't literally there. The result is a corpus of 4,400+ entities where every fact carries a source URL and the date it was verified.
A daily AI-free price scan writes into an append-only history, and a hash-chained ledger makes that history tamper-evident — you can't rewrite last month. The corpus fans out to 23,000+ citable pages, machine feeds built for AI readers, an MCP server with 19 tools, an open CC-BY mirror with a DOI, and a browser extension that overlays the price of record right on the store page.
