## Machine-readable pricing

A structured JSON pricing endpoint is available at:

```
GET /api/public/pricing
```

This returns the canonical tier data in a format suitable for agent consumption, ACP feed integration, and programmatic checkout.

## Purchase flow for agents

Agents cannot complete a Stripe checkout autonomously — card entry and 3D Secure require human approval. The sanctioned agent purchase path is:

1. Agent calls `POST /api/agent/purchase-intents` with `{plan, billing_cycle}`
2. Backend returns an **approval URL**
3. Human opens the URL and completes the normal checkout
4. Agent polls `GET /api/agent/purchase-intents/:id` for `completed` status

See [/agent#buy](/agent#buy) for full flow documentation.
