Apiosk - Apiosk

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.

The app

Create a team, ask questions, manage its balance and read saved results.

The API

Create an organisation key, browse sources and run a priced request.

MCP

Connect ChatGPT or Claude, review a plan and approve in the chat card.

Self-service setup

Sign up and choose a team account.
Confirm your email, then open Organisation → API keys as an owner or admin.
Set the key’s permissions and spending limits. The secret is shown once.
Follow the API quickstart, or connect an MCP client.

A direct call

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

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.

What the catalogue means

The directory lists verified sources, including entries that are currently discovery-only or restricted. A source’s available_in_v2, readiness and executable_capabilities show what can be planned now. The App, MCP server and API share executable contracts and the same price and saved-run ledger.
