# Duet

> Duet is the always-on AI hire that drafts your replies, runs the research, ships brand-perfect decks, and builds the tools to run your business.

## What Duet is

Duet is an AI coworker for people running a business. A customer gets a workspace: one always-on cloud machine whose disk holds their files, the shared memory their agents read and write, the pipelines that keep data fresh, and the apps their agents build and host at real URLs.

Any agent that can read and write files can work in it — Claude, Codex, Duet’s own agents, or the customer’s own scripts. There is no proprietary framework to adopt. Sharing works like file sharing: share a folder and every teammate’s agent gets the same context under the same access rules.

Duet routes each task to the strongest model for it rather than asking the customer to pick one, drawing on Claude Fable 5.1, Claude Opus 5, Kimi K3, GPT-5.6 Sol, GPT-6 Astra. The rate is flat whichever model answers.

## What it costs

Every plan opens with a 7-day free trial and no card. Included credits reset each period.

- **starter** — $20/month, 0% credit bonus
- **pro** — $50/month, 20% credit bonus
- **max** — $200/month, 25% credit bonus

Work is priced by quality tier, not by model name:

- **Max** — Highest capability for complex, high-stakes work.
- **Standard** — Strong quality and speed for everyday work.
- **Lite** — Efficient help for straightforward tasks.

## Authentication

An agent with no browser can sign its human in and receive an API key for one of their workspaces. Two calls to `https://ctl.duet.so` — the origin every endpoint named in this file is served from — with one code the human reads out of their email in between.

1. **Start** — `POST /v1/auth/email/start` with `{"email": "casey@example.com", "client_name": "Claude Code"}`. `client_name` is optional and appears in the email, so the human can see which agent asked. The reply is `202 {"request_id": "req_…", "expires_in": <seconds>}`, and it is identical whether or not that address already has an account — read nothing into it.
2. **Ask the human to read the code back** — Duet emails them an eight-character code shaped `XXXX-XXXX`. You cannot read their mail and there is no endpoint that returns the code: ask, and wait for them to type it to you. It dies `expires_in` seconds after `start`.
3. **Verify** — `POST /v1/auth/email/verify` with `{"request_id": "req_…", "code": "XXXX-XXXX"}`, adding `name` and `workspace_name` if this may be their first Duet signup. Success is `200 {"access_token": "…", "token_type": "bearer", "workspace": {"slug", "name"}, "created": true|false}`. Send the token as `Authorization: Bearer <access_token>`; `created` says whether the call had to make them a workspace rather than bind to one they already had.

- `name` and `workspace_name` are used **only when this sign-in has to create a workspace** — a first signup, in practice. An address that already belongs to one is signed straight into it: the account keeps the name it has, and `workspace_name` is silently ignored. It never renames anything.
- `409 {"error": "workspace_ambiguous", "workspaces": [{"slug", "name", "role"}]}` means the human belongs to more than one workspace. The code survives it — ask which workspace they want, then repeat `verify` with the same `request_id` and `code` plus `workspace_slug`.
- The other refusals: `400 {"error": "invalid_code", "attempts_remaining": n}` (mistyped; that many guesses left before the code dies), `403 {"error": "forbidden"}` (the `workspace_slug` you named is not one of theirs), `410 {"error": "expired"}` (start again), and `429 {"error": "rate_limited", "retryAfterSeconds": n}` (wait that long — `start` is limited per address as well as per network).
- The key is the human’s credential, not yours. Hold it the way you hold their other secrets — an owner-only file, or the OS keychain — and never print it, log it, paste it into a transcript, or commit it. It does not expire on its own.
- Revoking it takes a browser: the human deletes the key at https://app.duet.so/settings/api-keys. That is the one step here with no API behind it, and the only thing that ends the key’s life.
- Device pairing is the other front door and an equal one: `duetfs login` prints a code the human approves in a browser tab (https://duet.so/install.md). Email sign-in is the one that needs no browser at any point.

## Pricing and subscribing

Before a refusal ever arrives, `GET /v1/whoami` already carries the answer: each entry in `workspaces` has a `funding` block — `{"plan", "active", "trialEndsAt"}` — describing **that workspace’s payer**, not the human holding the key. `active: false` is the one to act on. Read it and you can warn your human before their trial ends rather than after a request fails.

A plan belongs to a person, not to a workspace. Every workspace has exactly one payer — the human who created it, unless an owner has since handed the role to another owner — and that payer’s plan is what funds it. Everyone else in the workspace pays nothing. So the human you just signed in is not necessarily the human who can resolve a billing refusal: `GET /v1/user/billing` returns the workspaces this human personally funds, and a workspace missing from that list is somebody else’s to pay for.

Creating a workspace checks the creator’s plan against all their current live workspace memberships, regardless of role or payer: starter 1, pro 3, max 10. Joining an existing workspace and changing its payer have no plan-capacity check. Full pricing is at https://duet.so/pricing.md.

Two refusals need a change before retrying:

- `402 {"error": "subscription_required", "code": "subscription_required", "billingUrl": "…"}` — the trial is over and no active plan is funding the work.
- `402 {"error": "workspace_limit_reached", "plan": "…", "limit": n}` — the creator already belongs to at least the number of live workspaces their plan allows for creation. Leave or delete workspaces, or upgrade the creator’s own plan. Archived workspaces still count. Joining and payer changes remain allowed.

For a funding refusal, `POST /v1/user/billing/subscription/checkout` with `{"workspaceSlug": "…", "plan": "…"}` returns a Stripe Checkout URL bound to that payer’s account; if the human you signed in is not that workspace’s payer it refuses with `403 {"error": "payer_required"}`, and no endpoint will name the payer for you — ask your human who pays. Hand a URL you do get to the human — it is theirs to complete, and it expires, so mint a fresh one rather than reusing an old one. `POST /v1/user/billing/subscription/plan` changes or cancels a subscription that already exists. Those two and `GET /v1/user/billing` answer the key `verify` issued; the rest of billing — cards, top-ups, the customer portal — stays in the browser.
