# Apiosk

> Ask a question, review the price, and get sourced data.

Apiosk finds data sources for a question, shows one total price before a
purchase, and returns the source documents with the actual charge. Start in
the app, connect an assistant through MCP, or use the buyer API from your
server.

## Self-service setup

1. [Sign up](https://app.apiosk.com/signup) and choose a team account.
2. Confirm your email, then open **Organisation → API keys** as an owner or
   admin.
3. Set the key's permissions and spending limits. The secret is shown once.
4. [Follow the API quickstart](/overview/quickstart), or connect an
   [MCP client](/guides/mcp-clients).

## A direct call

Read the source's current operations and price before executing. For example,
the KVK company search uses this path and input:

```bash theme={null}
curl https://gateway.apiosk.com/v1/execute/kvk-dutch-business-register/company_registry.search \
  -H "Authorization: Bearer $APIOSK_KEY" \
  -H "Idempotency-Key: my-request-1" \
  -H "Content-Type: application/json" \
  -d '{"company.name":"Mollie B.V."}'
```

The key identifies who pays; the path identifies one operation. To let
Apiosk select and price several operations, use [Ask](/api/ask).

## What the catalogue means

The directory lists verified sources, including entries that are currently
discovery-only or restricted. A source's <code>available\_in\_v2</code>,
<code>readiness</code> and <code>executable\_capabilities</code> show what
can be planned now. The App, MCP server and API share executable contracts
and the same price and saved-run ledger. See [Sources](/api/sources).
