免费开始

在 Free hosted secure storage 上创建 tenant。无需银行卡。

How signup works.

kotobase uses passwordless identity: a WebAuthn passkey for people, or a self-custodied Web3/DID key presented as a single-use CACAO through auth.kotoba.cloud. The wallet's recovery phrase signs you in without the wallet. Click 免费开始 to sign in or create your identity, then choose Free hosted secure storage or a paid plan scoped to your tenant DID.

1. Create your identity

Use a passkey, your own Ethereum wallet, or its recovery phrase at auth.kotoba.cloud. No password, no email, no company SSO.

免费开始

2. Choose a plan

Free is $0 and needs no card. Starter is $25/month (charged as ¥3,750) and Professional is $132/month (charged as ¥19,800); both open a tenant-scoped Stripe checkout. Business Critical ($292) is quoted by sales. Enterprise is a dedicated-deployment contract.

Business Critical — contact sales Enterprise — contact sales

3. Continue Free start

After you sign in on Free hosted secure storage, follow the continuous Free loop: biscuit, write, query, then pin. No founder step.

付费的 agent request 可能返回 HTTP 402 并要求 x402 payment。仅此一行。不是 status 声明。
