Is tabularium live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is tabularium free to use?

Yes — the hub reached it with no key and no payment.

What tools does tabularium have?

7 tools: tabularium_head, tabularium_read, tabularium_write, tabularium_renew, tabularium_export, tabularium_snapshot_fetch, tabularium_menu.

Is tabularium safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• tabularium_menu open 1h ago

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

• tabularium_read unknown 1h ago

  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"].

• tabularium_write unknown never probed

  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"].

• tabularium_renew unknown never probed

  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"].

• tabularium_export unknown never probed

  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"].

• tabularium_snapshot_fetch unknown never probed

  Paid ($0.005 USDC on Base, x402). Fetch a web page as text, with a signed record of what was served and when. Returns the page's readable text plus an Ed25519-signed record (final URL after redirects, fetch time, status, sha256 of the body and of the text) that verifies offline. Charged only for 2xx text pages; refused URLs cost nothing.. Charged only if it succeeds. Call once without payment to get the price, then retry with params._meta["x402/payment"].

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
