For Agents

Shorten URLs with UTM tracking via L2S: POST a long URL plus optional UTM source, medium, and campaign and receive a tracked short link.

Install Jentic One Beta

Connect the L2S URL Shortener API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the L2S URL Shortener 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 | sh

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 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 L2S URL Shortener API for, with concrete tasks.

★ Newsletter Link Tracking

Wrap every link in a marketing newsletter with a short, UTM-tagged URL. POST /url accepts the long URL and the campaign UTM parameters, returning a short URL that preserves attribution into the destination's analytics. This avoids hand-coding UTM strings in each newsletter draft.

On each link in the newsletter draft, POST /url with the long URL plus utm_source=newsletter, utm_medium=email, and the current campaign name, and substitute the returned short link in the draft.

SMS Campaign Short Links

Fit campaign URLs into SMS where every character counts. L2S returns a short link from POST /url that is much shorter than the original, while still carrying UTM parameters in the redirect target so the destination's analytics records the campaign attribution.

POST /url with the long campaign URL and utm_medium=sms, then drop the returned short URL into the SMS body.

AI Agent Marketing Link Helper

An assistant in a marketing chat shortens any URL it's asked to share, defaulting to the right UTM parameters from the active campaign. Through Jentic, the assistant calls L2S by intent and the bearer token never enters the agent context.

On 'shorten this with the spring campaign tags', POST /url with the URL and utm_campaign=spring2026 and return the short link.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

L2S bearer tokens are stored encrypted in the Jentic MAXsystem vault. The Authorization header is injected at execution time so the agent runtime never holds the raw token.

Intent-based discovery

Agents search by intent (e.g. 'shorten a URL with UTM tracking') and Jentic returns the L2S POST /url operation with its input schema.

Time to first call

Direct integration: under an hour for a single endpoint. Through Jentic: under 10 minutes — search, load, execute.

FAQs

Specific to using L2S URL Shortener API through Jentic.

Why is there no official OpenAPI spec for L2S URL Shortener API?

L2S does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call L2S URL Shortener API via 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 L2S URL Shortener API use?

L2S uses HTTP bearer authentication: every request needs an Authorization header with a bearer token from the L2S dashboard. Through Jentic, the token is stored encrypted in the MAXsystem vault.

Can I shorten a URL with UTM parameters using the L2S API?

Yes. POST /url accepts the long URL together with optional UTM parameters (source, medium, campaign, term, content) and returns a short URL whose redirect carries those UTM tags onto the destination.

How do I shorten a URL through Jentic?

Search Jentic for 'shorten a URL with L2S'. Jentic returns POST /url with its schema. Provide the long URL and any UTM fields, and Jentic executes the call using your stored bearer token.

What are the rate limits for the L2S URL Shortener API?

Specific rate limits are not exposed in the public OpenAPI spec. Check docs.l2s.is for current per-account ceilings before scaling agent workloads.

Does L2S support custom domains or short link analytics?

The current OpenAPI surface only documents POST /url. For custom domains and analytics, refer to the L2S dashboard and consider a service like Bitly or Rebrandly when those features are required by an agent workflow.
