# Pricing

The API is prepaid. You top up a balance, and each charged call takes its price from it. `usage.cost` on a response is the amount billed for it.

## Prices

All amounts are net of VAT.

| Call                         | Price                        |
| ---------------------------- | ---------------------------- |
| Answer, `depth: "standard"`  | €1.00                        |
| Answer, `depth: "deep"`      | €2.50                        |
| `POST /v1/provisions/search` | €0.05 per call               |
| `POST /v1/provisions/fetch`  | €0.05 per provision returned |

Checking a response with `GET /v1/responses/{id}` is free. Sandbox keys are free (see [Keys and sandbox](/guides/keys-and-sandbox)).

## What is charged

An answer is charged when the engine completes it, whether or not you ever fetch it. These outcomes are charged:

- a completed answer, including "no provision covers this"
- a cancel after answer text has started streaming

These outcomes are free:

- failed runs
- declined or refused turns
- a clarifying question instead of an answer, when it cites no source
- a cancel before any answer text was delivered

`usage.cost` is the billed amount, an object with two fields: `amount`, two decimals as a string, and `currency`, `EUR` or `HUF` (the account's currency). A charged answer has `{"amount": "1.00", "currency": "EUR"}`. For a free outcome and for the sandbox, `usage.cost.amount` is `"0.00"`. It is present once the run has ended. Ids that a fetch does not find are free.

A retry without `Idempotency-Key` is a new request and is charged again. See [Responses](/guides/responses).

## Top-ups

- The minimum top-up is €250, for every purchase.
- Presets are €250, €1,000 and €5,000, or a custom amount of at least €250.
- A top-up is valid for 12 months from the day it is credited.
- Top-ups are for companies only: checkout asks for a company name and a tax number. At launch, Hungarian companies and the EU companies Stripe Tax supports can buy.

Buy and manage top-ups at [https://console.azta.ai/billing](https://console.azta.ai/billing). Live keys and top-ups open at the public launch.
