`tabularium_export`Paid ($0.01 USDC on Base, x402). Full signed history and current values, verifiable offline.

The export verifies offline against the public key in /menu, with no trust in the server. The optional since parameter returns only newer entries.. Settles before it runs (a free check refuses a call that would fail). Call once without payment to get the price, then retry with params._meta["x402/payment"].	Paid ($0.01 USDC on Base, x402).

Reads a web page as clean markdown, as a person sees it: hidden text and invisible Unicode are kept out of the text and flagged with a prompt-injection verdict. Also reads PDF, Word and Excel files as markdown. Includes an Ed25519-signed record (final URL, time, status, sha256 of body and text) that verifies offline.
