Install Jentic One Beta

Connect the Checkin.no API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Checkin.no API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fcheckin.no%2Fcheckin-no" | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fcheckin.no%2Fcheckin-no" | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Use Cases

Patterns agents use Checkin.no API for, with concrete tasks.

★ Event Day Check-In

Run an on-site check-in app that scans participant codes and marks them as arrived. The app sends a GraphQL mutation to /graphql to update the participant's check-in status, then queries for the next list of pending arrivals. Suitable for races, conferences, and ticketed events using Checkin.no as the source of truth.

Send a GraphQL mutation to /graphql that marks participant with reference 'ABC123' as checked in and return the updated status.

Participant Reporting

Pull participant lists for an event into a CRM, finance system, or analytics dashboard. A scheduled job sends a GraphQL query to /graphql requesting events and their participants, transforms the results, and writes them downstream. Useful for organisers who run multiple events on Checkin.no and need consolidated reporting.

Send a GraphQL query asking for all events created in the last 30 days and the number of registered participants in each.

Booking Lookup Service

Build a self-service booking lookup that lets participants find their confirmation by name or reference. A small service forwards the lookup as a GraphQL query to /graphql and returns the matched booking details. Useful when participants lose their confirmation email and need to recover their entry on the day.

Send a GraphQL query searching bookings by the email 'jane@example.com' and return the matching booking's reference and event.

AI Agent for Event Operations

An autonomous agent reads natural-language requests from event staff ('how many checked in?', 'check in the next 10 runners by bib number') and translates them into GraphQL operations against /graphql via Jentic. The Authorization header is held in your Jentic One instance, so the agent never sees the API key.

Through Jentic, search 'execute a GraphQL query', load the schema for /graphql, and submit a mutation that checks in participant reference 'ABC123'.

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring Checkin.no by hand means handling its Authorization header key and composing valid GraphQL documents against its single endpoint yourself. Through Jentic you install once, import the Checkin.no API from the API Directory, store the key once, and your agent calls it.

Permission scoping

Checkin.no exposes a single /graphql operation, so scope the agent to that operation and the registration and check-in queries it needs. You choose that set, so the agent runs only the queries and mutations you allow.

Credential isolation

Your Checkin.no API key is stored once, encrypted, by your own Jentic One instance and injected into the Authorization header at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'register an event participant' or 'check in an attendee', and Jentic returns the /graphql operation with its input schema so the agent submits the right GraphQL document without browsing the reference docs.

FAQs

Specific to using Checkin.no API through Jentic.

Why is there no official OpenAPI spec for Checkin.no API?

Checkin.no exposes a GraphQL API and does not publish an OpenAPI specification. Jentic generates and maintains this spec, wrapping the GraphQL endpoint so AI agents and developers can call Checkin.no via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the Checkin.no API use?

Checkin.no uses an API key passed in the Authorization header. Through Jentic, the key is stored encrypted in your Jentic One instance and injected at execution time, so it never appears in the agent's context.

Is the Checkin.no API REST or GraphQL?

GraphQL. There is a single POST /graphql endpoint that accepts a query or mutation in the request body. Operation type and field selection are driven by the GraphQL document, not the HTTP path. The interactive GraphiQL explorer is at https://api.checkin.no/graphiql for browsing the schema.

Can I check in participants with the Checkin.no API?

Yes. Send a GraphQL mutation to POST /graphql that updates the participant's check-in status. The response returns the updated participant and event records, which you can then display to event staff or pipe into a kiosk app.

What are the rate limits for the Checkin.no API?

The OpenAPI specification does not declare formal rate limits. Plan for retry-with-backoff on 429 responses and avoid overly broad GraphQL queries - request only the fields you need on each call.

How do I run a Checkin.no GraphQL query through Jentic?

Install the SDK with `pip install jentic`, then call Jentic.search('execute a GraphQL query'), load the schema for /graphql, and execute with your GraphQL document and variables. Jentic injects the Authorization header from your Jentic One instance.

Can I limit what my agent is allowed to do with the Checkin.no API?

Yes. Checkin.no exposes a single POST /graphql operation, and because Jentic One is self-hosted by you, your own rules decide which GraphQL queries and mutations the agent may send through it. You can allow only the registration, participant-lookup, and check-in operations you need and withhold the rest, so the agent runs no operation you have not permitted. The Checkin.no API key stays in your Jentic One instance and is injected into the Authorization header at execution time, so the agent never sees it.

For Agents

Send GraphQL queries and mutations to Checkin.no for managing events, bookings, participants, and check-in flows.

Use for: Run a GraphQL query against Checkin.no to list events, Fetch all bookings for a specific event in Checkin.no, Find a participant by registration number, Check in a participant on event day via Checkin.no

Not supported: Does not handle payment processing, marketing campaigns, or hotel bookings - use for event registration, participant lookup, and on-site check-in only.

Jentic publishes the only available OpenAPI specification for Checkin.no API, keeping it validated and agent-ready. Checkin.no is a Norwegian event registration and ticketing platform widely used for sports events, conferences, and races to handle entries, payments, and on-site check-in. Its API is GraphQL-based and exposed at a single /graphql endpoint that accepts queries and mutations covering events, bookings, participants, and check-in flows. The same endpoint serves both reads and writes, with operation selection driven by the GraphQL document supplied in the request body.
