Four services, one balance

Each service keeps its own rate card. All of them draw on the same prepaid balance, and every response says what it cost.

Models

X1-Kaer and the catalog behind one OpenAI-compatible endpoint. Bring the SDK you already use.

From $0.06 per 1M input tokensDocs

Search

Kaer's own web index in about 80 ms, a fast lane racing the open web, and a deep lane that reads and re-ranks.

From $0.50 per 1,000 queriesDocs

Maps

Geocoding, routing, places and weather, each a single call, billed per request with no monthly plan.

From $0.0050 per 1,000 requestsDocs

Mail

A hosted sender for transactional mail from a signed kaer.dev address, once your account has a payment history.

$1.00 per 1,000 messages, plus recipientsDocs

Prepaid, settled to the unit

Every call reserves before it runs and settles after, so nothing arrives as a surprise bill. See pricing for every rate.

  1. 01

    Reserve

    Before a call runs, its worst case is held from your balance. No balance, no call.

  2. 02

    Run

    The model, search, map or mail request does its work. Nothing has been charged yet.

  3. 03

    Settle

    The real cost is taken and the rest released. A balance can never go below zero.

New accounts start with $5 of free credit for language models, once per network, device and inbox. Search, maps and mail run on paid credit from your first top-up.

Turn on automatic top-up and a fixed amount you choose is added before the balance runs out. Special privacy terms, such as zero retention, go through enterprise.
