For Agents
Manage Cituro customers, services, employees, and company settings for an appointment-booking business. Supports creating bookings prerequisites, updating customer records, and listing services with their assigned staff and locations.
Use for: I need to create a new customer in our gym booking system, Update a customer's contact details before sending a reminder, List all services we offer and which employees can deliver them, Find all employees assigned to a yoga class service
Not supported: Does not handle payment processing, calendar event creation, or marketing email — use for managing the customer, service, and employee records behind a Cituro booking experience only.
Jentic publishes the only available OpenAPI specification for Cituro API, keeping it validated and agent-ready. Cituro is an appointment booking and resource scheduling platform used primarily by gyms, studios, and service businesses to manage customers, services, employees, and bookable locations. The API exposes customer profiles with notes, configurable services, employee assignments, and company-level settings, so a booking front-end or back-office tool can read and modify the full scheduling graph. It uses an X-API-KEY header (or HTTP Basic with the key as the username) and returns standard JSON resources for each entity.
Install Jentic One Beta
Connect the Cituro API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Cituro 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://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic 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.
Capabilities
What an agent can do with Cituro API.
Create and update customer profiles with attached notes for an appointment-booking business
Configure bookable services and link them to the employees who can deliver them
Maintain employee records and the locations where each employee works
Read and patch company-level settings such as opening hours and contact details
Look up the authenticated account's identity via the /me endpoint for token introspection
List the locations a specific service can be booked at and replace the location set in one call
Use Cases
Patterns agents use Cituro API for, with concrete tasks.
★ Customer database sync for a studio chain
Keep an external CRM or marketing tool aligned with the Cituro customer list by pulling customers via GET /customers and pushing edits with PATCH /customers/{id}. The API supports per-customer notes through /customers/{id}/notes, so qualitative context from staff stays attached to the canonical record. Useful for studios that want their newsletter audience and Cituro contact list to match without manual exports.
List all customers modified in the last 30 days, then PATCH each one whose email changed in the source CRM
Service catalogue and staffing maintenance
Manage the menu of bookable services and the employees assigned to each one. Agents can create a new service via POST /services, update its details with PATCH /services/{id}, and read the assigned staff via GET /services/{id}/employees. Locations available for a service are managed through /services/{id}/locations, including a full replacement with PUT.
Create a new 60-minute Pilates service priced at 30 EUR, assign two named employees, and set its location to studio-A
Company profile audit
Read company-wide configuration with GET /company and apply controlled edits via PATCH /company. This is the right entry point for an agent that needs to verify or correct top-level information such as the legal name, contact email, or address before it appears on a booking widget.
GET the company profile, check that the support email matches a known good value, and PATCH it if it does not
Agent integration via Jentic
Through Jentic, an AI assistant can take an instruction like "add a new customer named Marie Dubois with this email" and resolve it to the correct Cituro endpoint, schema, and authentication header without the developer wiring the call by hand. Jentic stores the X-API-KEY in its credential vault and only injects it at execution time.
Search Jentic for 'create a customer in Cituro', load the schema for POST /customers, and execute it with the parsed name and email

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Cituro X-API-KEY values are stored encrypted in the Jentic vault. The agent receives a scoped reference, never the raw key, so prompts and logs cannot leak it.
Intent-based discovery
Agents search Jentic with intents like 'create a Cituro customer' or 'list services with their employees'. Jentic returns the matching operation, its input schema, and the auth requirement so the agent can call it directly.
Time to first call
Direct integration against the Cituro PDF reference: 1-2 days to read the doc, model the endpoints, and wire auth. Through Jentic: under 30 minutes — search, load schema, execute.

FAQs
Specific to using Cituro API through Jentic.
Why is there no official OpenAPI spec for Cituro API?
Cituro does not publish an OpenAPI specification — the public reference is a PDF on cituro.com. Jentic generates and maintains this spec from the documentation so AI agents and developers can call Cituro through structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the Cituro API use?
Cituro accepts an API key sent in the X-API-KEY HTTP header, or HTTP Basic Authentication where the API key is the username and the password is left empty. Through Jentic, the key is stored encrypted in the credential vault and never enters the agent's prompt context.
Can I create and update customers with the Cituro API?
Yes. POST /customers creates a new record, GET /customers/{id} reads one, and PATCH /customers/{id} applies a partial update. You can also attach freeform notes via POST /customers/{id}/notes and edit them with PATCH /customers/{id}/notes/{noteId}.
How do I assign employees to a service through Jentic?
Search Jentic for 'list employees for a Cituro service', which returns GET /services/{id}/employees, then use POST or PATCH on the service or employee resources to adjust assignments. The Jentic SDK loads the input schema so the agent fills in the right fields without reading the raw spec.
What are the rate limits for the Cituro API?
The OpenAPI spec does not declare formal rate limits. Treat 429 responses as rate-limited and back off; for production use, contact Cituro support to confirm the per-account quota that applies to your key.
Does the Cituro API expose booking creation directly?
The endpoints in this spec cover the prerequisites for bookings — customers, services, employees, locations, and company configuration — rather than a write endpoint for an individual appointment. Use these endpoints to keep the booking graph in sync with external systems.
