Is baselens live?

Yes — it answered the hub's last check (checked 50m ago). It answered 100% of checks over the last 30 days.

Is baselens free to use?

Partly — some of its tools are open, others need a key or payment.

What tools does baselens have?

11 tools: base_token, base_price, base_tx, base_address, base_erc20_balance, base_transfers, base_contract, base_free_gas_sample, ….

Is baselens 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.
