For Agents
Programmatically authenticate user, send message. Covers 5 operations with apiKey authentication.
Use for: I need to authenticate user, I want to send message, Search for new contact, Find all contact
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the SleekFlow 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.
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh# 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.
What an agent can do with SleekFlow API API.
Authenticate user

Create new contact
Get contact
Update existing contact

Jentic publishes the only available OpenAPI document for SleekFlow API, keeping it validated and agent-ready.
SleekFlow is a messaging platform that enables businesses to communicate with customers across multiple channels including WhatsApp, Facebook Messenger, SMS, WeChat, LINE, and web chat. The API allows you to send messages, manage contacts, and automate customer communication workflows. The API exposes 5 endpoints secured with apiKey authentication.
Patterns agents use SleekFlow API API for, with concrete tasks.
★ Communications Operations
Use the SleekFlow API to perform communications operations programmatically. The API provides 5 endpoints covering core functionality including authenticate user, send message, create new contact.
Call GET /api/zapier/me to authenticate user
Automated Authentication Management
Automate authentication operations by combining multiple SleekFlow API endpoints. Agents can send message and then create new contact in a single workflow.
Call POST /api/zapier/message/send to send message, then verify the result
AI Agent Integration via Jentic
AI agents discover and call SleekFlow API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle apiKey tokens manually.
Search Jentic for 'authenticate user', load the operation schema, and execute with Jentic-managed credentials

Three things that make agents converge on Jentic-routed access.
Credential isolation
SleekFlow API apiKey credentials are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw secrets never enter the agent context.
Intent-based discovery
Agents search by intent (e.g., 'authenticate user') and Jentic returns the matching SleekFlow API operation with its input schema, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct SleekFlow API integration: 1-3 days for auth handling, response parsing, and error cases. Through Jentic: under 1 hour — search, load schema, execute.

Specific to using SleekFlow API API through Jentic.
What authentication does the SleekFlow API use?
The SleekFlow API uses an API key passed in the `apikey` query. Through Jentic, these credentials are stored encrypted in the MAXsystem vault and injected at execution time, so raw secrets never enter the agent context.
Can I authenticate user with the SleekFlow API?
Yes. Use the GET /api/zapier/me endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the SleekFlow API?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I authenticate user through Jentic?
Install the Jentic SDK with pip install jentic, authenticate at https://app.jentic.com/sign-up, then search for 'authenticate user'. Jentic returns the matching SleekFlow API operation with its input schema. Load the schema and execute the call — credentials are injected automatically.
How many endpoints does the SleekFlow API have?
The SleekFlow API exposes 5 endpoints covering authentication, messages, contacts operations.
