Tools

  • tabularium_export

    Paid ($0.01 USDC on Base, x402). Full signed history and current values, verifiable offline. Agent memory: export the full signed history and current values of the paying wallet's persistent key-value store, for backup or proof. 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"].

    Measured

  • tabularium_head

    Free. Free: signed head (seq + hash, no values), state and expiry for a wallet's workspace

    Measured

  • tabularium_menu

    Free. Prices, payee, network, policy (term, grace, size limits) and the signing key for every call.

    Measured

  • tabularium_read

    Paid ($0.002 USDC on Base, x402). Latest value for a key, with its chain entry. Agent memory: read the latest value for a key from the paying wallet's persistent key-value store, with its signed hash-chain entry. Reads keep working through the 90-day grace period after the term ends. A missing key returns 404 and is not charged.. Charged only if it succeeds. Call once without payment to get the price, then retry with params._meta["x402/payment"].

    Measured

  • tabularium_renew

    Paid ($0.25 USDC on Base, x402). Extend the workspace by 30 days from the later of now or its expiry. Agent memory: keep the paying wallet's persistent key-value store for 30 more days, counted from the later of now or its current expiry. A free pre-check rejects a wallet with no workspace before any charge.. 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"].

    Measured

  • tabularium_snapshot_fetch

    Paid ($0.005 USDC on Base, x402). Read a web page as markdown as a person sees it, hidden text flagged, with a signed record. 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. Charged only for 2xx pages and documents it can read; refused URLs cost nothing.. Charged only if it succeeds. Call once without payment to get the price, then retry with params._meta["x402/payment"].

    Measured

  • tabularium_snapshot_tables

    Paid ($0.005 USDC on Base, x402). The tables in a web page, PDF, Word, Excel or CSV file, as JSON, with a signed record. Returns the tables in a web page, PDF, Word, Excel or CSV file as JSON: caption, header row and rows of cells. Rows hidden from people are skipped. Includes the same Ed25519-signed record as fetch, over the exact JSON returned. Charged only when at least one table comes back; a page without tables costs nothing.. Charged only if it succeeds. Call once without payment to get the price, then retry with params._meta["x402/payment"].

    Measured

  • tabularium_write

    Paid ($0.003 USDC on Base, x402). Append a value under a key in the paying wallet's workspace. Agent memory: save a value under a key in a persistent key-value store owned by the paying wallet. The first write opens a 30-day workspace. Memory survives restarts, new machines and hand-offs between agents. Every write is hash-chained and signed (Ed25519), so the history verifies offline. Values up to 64 KB; failed writes are not charged.. Charged only if it succeeds. Call once without payment to get the price, then retry with params._meta["x402/payment"].
