zeekay ef25942f3a agents: sign up with a wallet, no human, and every page says where to start
A first-seen wallet signs a hanzo.id challenge, gets its own account and
organization on the Free plan, mints a key, makes a free call and asks for
a USDC deposit address: one TypeScript file, run as printed against
production, drawn at /agents#headless and named first in the prompt and
in llms.txt.

Every page's head now names /llms.txt, /agents, the API catalog and the
OpenAPI document; the Developers menu and its footer column lead with
"Agents: get an API key in one call"; the API catalog lists the sign-in,
key, deposit and MCP addresses.

# Hanzo
> The AI operating system for business. Building business software since 2014. Techstars '17.
Hanzo is where a business runs its work with AI: Chat, Dev (the coding agent),
Studio, Tabs, Bot, and one API at https://api.hanzo.ai/v1 for every model, Kai
decisions and agents, behind one key. Run it on Hanzo Cloud or on your own
infrastructure. Start free: 50 requests a day, no card.
Enso is the intelligence layer: one endpoint that reads the objective, applies
your policies and puts the right model behind the work. Zen is the open-weight
family. Both run beside the rest of the catalog on the same endpoint and the
same key.
Kai is the decision model: typed questions about a state (choice, noul, score),
answered with calibrated distributions instead of generated text, at
`POST https://api.hanzo.ai/v1/decisions`. Docs: https://docs.hanzo.ai/docs/decisions
Install: `curl -fsSL hanzo.sh | sh`
API reference for agents: https://docs.hanzo.ai/llms.txt
Skills for agents: https://hanzoskills.com/llms.txt
## For agents
No human required: sign in with a wallet, get a key, call the API, top up in USDC.
- Headless sign-up with a wallet: `GET https://hanzo.id/v1/iam/web3/nonce?chain=evm&address=<address>`, sign the CAIP-122 message with EIP-191, `POST https://hanzo.id/v1/iam/web3/verify` (type "code" with PKCE), exchange the code at `https://hanzo.id/v1/iam/oauth/token`, then `POST https://api.hanzo.ai/v1/account/keys`. A first-seen wallet gets its own account and organization on the Free plan. The whole flow as one TypeScript file: https://hanzo.ai/agents#headless
- Start here: https://hanzo.ai/agents, and https://docs.hanzo.ai/docs/agents for every request spelled out.
- The prompt to paste into an agent is below, and at https://docs.hanzo.ai/docs/agents/prompt.
- Get a key with a person nearby: `hanzo auth login` (on a machine with no browser it prints a link and an 8-character code your person approves on any device), then `export HANZO_API_KEY="$(hanzo auth token)"` or `hanzo account keys create --name agent --type secret`. An agent with its own inbox signs up over HTTP: https://docs.hanzo.ai/docs/agents
- Free: the Free plan is 50 requests a day per person on `zen-free` and `enso-free`, and 50 Kai decisions a day, no card. Plans and prices: `GET https://api.hanzo.ai/v1/billing/plans` (no key needed), https://hanzo.ai/pricing
- Pay: card, Apple Pay or Google Pay at https://hanzo.ai/pay; or, with no human, USDC (Base, Ethereum, Solana) and USDT (Ethereum) over the API: `POST https://api.hanzo.ai/v1/billing/crypto/deposit` returns a per-payer address, valid 24 hours, credited when the chain confirms.
- Bound spend: a key takes a monthly budget in cents and a rate in requests a minute; a session takes a cap at `POST /v1/agent/sessions/{id}/budget`.
- Evaluate Kai: `POST https://api.hanzo.ai/v1/decisions`; the frozen harness is public at https://github.com/hanzoai/benchmarks (decision/); published runs, no key needed: https://api.hanzo.ai/v1/research/runs?org=hanzo&benchmark=app.phishing
- Tools: `npx -y --package=@hanzo/mcp@latest hanzo-mcp serve` is an MCP server over stdio for Claude Code, Codex, Cursor and Zed.
- Skills: `npx skills add https://hanzoskills.com/hanzo.md`, and the index at https://hanzoskills.com/llms.txt
- Every operation: https://api.hanzo.ai/v1/openapi.json, also listed in https://hanzo.ai/.well-known/api-catalog

## Company
- Building business software since 2014; the commerce platform's first commit is dated 2014-09-29, and it has been a Go-native platform since October 2014. Founded as Crowdstart (crowdstart.com), a crowdfunding and commerce platform, and renamed Hanzo in 2016.
- First customer, 2014: SKULLY, the fastest fully funded campaign on Indiegogo, raising $1M in about 45 hours (TechCrunch, 2014-08-14: https://techcrunch.com/2014/08/14/the-skully-smart-helmet-is-the-fastest-funded-indiegogo-campaign-to-hit-1m/).
- AI and machine learning in commercial use since 2014; GPT models in production by 2019.
- The first blockchain-native commerce platform, 2017: the Unikrn ICO raised over 120,000 ETH (Crunchbase News, 2017-10-24: https://news.crunchbase.com/startups/found-ico-makes-sense/).
- Techstars '17: https://hanzo.blog/2017-06-08-techstars-17/ and Startland News, 2017-10-10: https://startlandnews.com/2017/10/techstars-spotlight-hanzos-e-commerce-tools-designed-to-make-you-money/
- Hundreds of venture-funded startups, backed by Y Combinator, 500 Startups, Techstars and other tier-1 firms: billions in client revenue, two companies taken past 100 million users, and two that went public on Nasdaq in 2024, Damon Motorcycles and Triller.
- Damon Motorcycles' CES 2020 launch ran on Hanzo: $8.4M of motorcycles sold in 30 days at a 541:1 return on ad spend, with AI-generated ads (https://hanzo.ai/customers/damon-motorcycles).
- A decade of running commerce, analytics and marketing for that portfolio is what Hanzo's AI is built on.
- Led by CEO Antje Worring (https://www.linkedin.com/in/antje-worring/) and CTO Zach Kelling (https://www.linkedin.com/in/zeekay/, https://github.com/zeekay).
