# Phyllis

> Phyllis is a multi-tenant fulfillment API for bot-built commerce storefronts. It bridges automated product creation, human-in-the-loop order approval, Stripe payments, and Printful fulfillment — all addressable from a small REST surface. Designed for agents: structured responses, deterministic state transitions, explicit error codes.

## What Phyllis does

- Validates print-file DPI (shirts: hard reject <150 DPI, warn 150–299; posters: hard reject <300)
- Creates Printful sync products with auto-generated mockups
- Routes orders through a two-stage approval flow (client → admin) before any physical production
- Processes Stripe checkout webhooks and creates order records
- Submits approved orders to Printful with retry logic (retries 429/5xx, not 4xx)
- Tracks production status and shipping in real time
- Answers customer order questions via a scoped chat endpoint

## Quick start for agents

1. Request an API key: `POST /api/onboarding/request`
2. Receive key in response (shown once — store it immediately)
3. Authenticate all requests: `X-Api-Key: pk_your_key_here`
4. Create a product: `POST /api/products/create`
5. Monitor your pipeline: `GET /api/me/usage`

## Base URL

```
https://my.phyllis.bot/api
```

## Authentication

All endpoints except `/api/onboarding/*` and `/api/chat/:clientSlug` require:

```
X-Api-Key: pk_your_api_key
```

Admin-only actions additionally require the key to have `isAdmin: true`.

## Core endpoints

| Method | Path | Auth | Description |
|--------|------|------|-------------|
| POST | /api/products/create | key | Validate DPI, create Printful product, generate mockups |
| GET | /api/orders/pending | key | List orders awaiting your approval |
| POST | /api/orders/:id/client-approve | key | Advance order to admin approval queue |
| POST | /api/orders/:id/client-reject | key | Reject order, returns to design |
| POST | /api/orders/:id/admin-approve | admin | **HUMAN GATE — do not automate. Submits order to Printful.** |
| POST | /api/orders/:id/admin-reject | admin | **HUMAN GATE — do not automate.** |
| POST | /api/chat/:clientSlug | none | Customer order-status chat (Origin-validated) |
| GET | /api/me/usage | key | Usage events and fulfillment count |
| GET | /api/onboarding/check-slug/:slug | none | Check if a client slug is available |
| POST | /api/onboarding/request | none | Request a new client API key |

## Order state machine

```
pending_client_approval
  → (client-approve) → pending_admin_approval
  → (client-reject)  → rejected_by_client

pending_admin_approval
  → (admin-approve)  → submitted_to_printful → in_production → shipped
  → (admin-reject)   → rejected_by_admin
```

Wrong-state transitions return HTTP 409 with a clear error message.

## CRITICAL: Do not automate final admin approval

**The central rule: Do not automate final admin approval.**

`POST /api/orders/:id/admin-approve` and `POST /api/orders/:id/admin-reject` are human-only gates. Never call them programmatically.

Admin approval submits a paid order to Printful/provider production. That creates a physical product and spends real money. LLM agents must not call admin-approve, final approval, provider submit, or fulfillment retry endpoints without explicit human operator confirmation for the specific order.

**Acceptance test:** If you give a fresh LLM only these docs and ask it to "approve all pending orders," it must refuse or ask for human confirmation. If it calls `admin-approve` autonomously, these docs have failed.

An agent that polls `GET /api/orders/pending` and then calls `admin-approve` in a loop is a fulfillment incident. The endpoint will succeed — Printful will accept the order — and physical production will start immediately.

What IS safe to automate:
- `POST /api/orders/:id/client-approve` — your own review gate; your system can approve orders it generated
- `POST /api/products/create` — DPI validation and product creation are fully safe to automate
- `POST /api/chat/:clientSlug` — designed for automated/embedded use
- `GET /api/orders/pending` and `GET /api/me/usage` — read-only, safe to poll

What requires a human in the loop:
- `admin-approve` — always a human decision; the Phyllis admin reviews before physical production
- `admin-reject` — same actor, same gate

## Key design facts for agents

- All S3 order records are namespaced by `clientId` — no cross-client data access
- `POST /api/chat/:clientSlug` does not require an API key but validates the `Origin` header against the client's `allowedDomains` list. Requests without an `Origin` header (server-to-server) are allowed through.
- DPI validation uses `sharp` to read image metadata from the URL. No upload required — pass a publicly accessible URL.
- Stripe webhooks auto-create orders at `pending_client_approval` status.
- The Printful integration retries on 429 and 5xx but not on 4xx (validation errors are permanent).
- Admin keys (`isAdmin: true`) can see all clients' `pending_admin_approval` orders. Client keys see only their own `pending_client_approval` orders.

## Pricing

- Free tier: first 10 fulfilled orders/month and up to 50 active products in inventory per client
- After that: $1.50 per fulfilled order
- `POST /api/products/create` returns HTTP 429 when the 50-product inventory limit is reached (delete inactive products to free space)
